No more "High End" for me...Back to Reality Audio


After a 3 year roller coaster ride with so called "Audiophile High End" Tube Amps,/Tube Preamps, multi thousand dollar DAC's, Speakers of all shapes and sizes, and several DIY mods. I've settled on what will be my "forever system" and stop chasing a Dragon that I'll never catch. There's more important things in life to worry about. Plus HIgh End crap can be very fickle at times. It has taught me though what sounds good and how to get there and of course how much it will cost new or slightly used.

For the first time, I'm building a system around the Speakers. I'm an electronics Geek so that has ALWAYS come first. I've always done DIY Speakers as well form High School to College to married life (my Wife puts up with A LOT).

My Bose 901 "passion" will be with me forever. I will defend those Sealed Box odd shaped boxes till I do. Any old Geezer will be told off wherever they knock that Brand down. I did it last last week.

Anyways, the list :

  • Klipsch Cornwall IV's driven by a pair of resto modded McIntosh MC50's
  • Sony UBP-X1000ES (gotta get some more before they and the 1100ES become as rare as the overpriced Oppo crap) with my mods to the Analog Output boards
  • Orchard Audio Ultra Amplifers x6 (I'm getting near the end of hand buiding/soldering the 6 pcb's)
  • Stax SRM-007tA with Koss 95/X Electrostatics
  • Surround Speakers will be 4x Series I/II Speakers with two on Tulip Stands and two more hung from the ceiling (what the Wife can see sitting down but can hear is always a good thing)
  • Center Channel with be two Heresy's resting horizontally angled up towards the screen slightly
  • two double stacked 12" H-Frame Subwoofers on the back wall 
  • All the Electronics will be mounted in the wall giving lots of space for the Cornwall to do their "thang"

To those still chasing the Dragon. Enjoy !

I just returned my friends KEF R3’s and in turn he lent me a pair of PMC TB2’s while I wait to payoff the Gentleman with the Cornwall IV’s and pick them up in 3 weeks.

Anyone who says nearfield Studio Monitors can’t be repurposed as Home Speakers is f.o.s. It’s just Speaker drivers and a crossover in a box ! In these little boxes, there’s a Transmission Line. So Bass is limited by design and I actually had to add a mild boost above 10kHz and a large boost below 100Hz.  They sound very very three dimensional but lack the Bass extension of the R3’s.

”I like Big Bass and I cannot lie”

congrats to you.

you lost me at Sony UBP-X1000ES and surround speakers.

personally i am thinking about the same topic, selling off and simplifying.  smaller speakers, integrated tube amp, ditching the subwoofers.  

Here’s an honest look at myself: I appreciate good sound. I don’t have any kind of engineering background. Some acoustic things I understand,however,many I don’t. I can hear the end result,but I can’t tell you how to achieve that. You on the other hand, understand the technical aspects of sound. How one thing effects another. You can apply that knowledge and fabricate devices to work towards better acoustics. Sometimes,people like me have to pull out the old wallet to get there. Others are content with everything around them. That’s kool and the gang! I always looked at audio as a hobby, good music,good sound. Some jump into a rabbit hole,some don’t.
I look at this like hi performance cars. All the horsepower in the world is useless,if you can’t put it to the ground. I’m getting to the point where I’m trying to put that power to the ground,but I’ll probably always be chasing more.

You are very right our journey is specific to ourself...Thanks to remind me that, i need it sometimes being a bit too passionnate and centered on myself...

But a remark:

The audio  journey is defined by precise acoustical and psycho-acoustical criteria of experience, TIMBRE being one of the most important, dynamic, imaging and soundstaging, listener envelopment and some other one; all these factors are perfectly defined SCIENTIFIC  acoustic experience on which we can increase our control with acoustic experiments OR NOT...

Playing by changing components for the sake of changing components is fun yes but could not replace the power of transformation of acoustic experiments...

I dont enjoy myself the difference but i prefer to enjoy at the end music toself, BUT  with no frustation about any aspect of sound in my room/system... Then i dont need any change ....

My best to you....

In my opinion,all things regarding sound reproduction matter. Especially the room. Why did you think I was only speaking about gear? I enjoy trying different ways to couple,decouple, isolate components. Therefore,until I stop enjoying the differences these things make,I will probably not reach my destination. Have you reached yours? Are you done experimenting with different ideas? If someone has reached their endgame,that’s awesome. This is a hobby. Something to be enjoyable,and bring some pleasure in this life. People have different experiences and different goals.
Enjoy the music,

Ray

Adequation and synergy between the CHOSEN audio system and the room is the destination...

Chasing gear without adapting acoustically the room for the system does not preclude the enjoyment of spending money for sure , but upgrading gear is not ACOUSTIC experience...It is acoustic ignorance if upgrading is done for the sake of changing the pain’s place or the "tasted" colors...Sorry....

My definition of the journey is not the same as you...

The better ratio of S.Q. / cost for listening MUSIC....Thats all....

A high end sound which is not created by a high end system but by acoustic at peanuts cost...This is my journey...

Is it no an interesting journey?

I prefer that to meaningless upgrade because ignorance of basic acoustic...

Audio is acoustic FIRST and electronic engineering second...not the reverse...Guess why?

😁😊

If you have reached your destination in this hobby, congratulations. I will more than likely never reach a destination. For me,that’s part of the enjoyment. I don’t find it frustrating,I find it invigorating.

I do agree that high end can be fickle especially on less than perfect recordings. I have a set that sounds very very good on any damn thing. Have another set that sounds amazing with some recordings and dull and messy with not so well recorded material. 

There is high end sound and there are high end products. Two different things.

Very well said !

I myself distinguish very precisely between gear upgrade related to high end products and acoustic control related to high end sound quality...

You can have high end products with a not so well high end sound quality, but you can also have high end sound quality with relatively low cost components which had a relatively basic good design for sure...

Price tag is a red herring ... Acoustic is the key....

 

 

@waytoomuchstuff +1. 8 and 9 are just two of the extensive mods I've done to my Klipschorns, upgrading over SonicCaps certainly worthwhile. Tractrix horns and John Allen A-55G mid driver also very nice!

 

With Klipsch Heritage one needn't spend a fortune on amplification, for the Khorns a nice little 2a3 could do a fine job. 300B's also don't have to be most expensive of amps.

DIY modded Klipsch Heritage and low power SET would make basis for system with top line sound at budget price.

There is high end sound and there are high end products.   Two different things. 

@gkr7007 

Absolutely on board with #1-6 related to your Cornwall performance mods. I like to add a few more:

7) replace all internal cabling with the same (or better) cabling used from the amplifier to speaker terminals.

8) bypass PC traces on crossover board  and replace with point-to-point wiring (same quality as above)

9) remove all crimped-on connectors/spades and direct silver-solder to raw driver lugs (preferably at the point where the tinsel lead connects to the lug) and input terminals.

This will allow the Cornwalls to take on more of the character of a "polite British loudspeaker" while actually increasing the dynamic impact that the "big Klipsch's" are famous for.

Every time I make a purchase "OK, done. I've got what I need for a GOOD LONG TIME, probably will never buy another thing". Nope. Never happens.      Audioholics Anonymous? Let's meet in the church basement.

From what I learned , that we all chase the sound , we listen to the speakers , amplifiers , sources , cables and all of the above , the most important is , that  we forget about the music . Most of us neglect the best recordings because It does not sound right .At work I listen to all recordings  from a cheap sound bar and I feel that I have more appreciation for the music , I feel like I focus more on composition than on the quality of the sound .

Good 4 you. It’s a waste of money. Keep everything under a strict budget and ignore the latest and greatest. 

Congratulations 

I went through this three years ago when I relocated 

I’m released from expensive cable  amps pre amp etc etc etc

I’m free and enjoying MUSIC! 

I just re equipped a listening room for a mere fraction of one of my past

 and just thrilled!

There's a saying in sports .. stay out of other people's pockets! I'm always tickled at how passionate folks get about what other people spend on their enjoyment. The speed limit is 55 mph, that doesn't stop me from driving a performance car. Enjoy your Prius but don't throw shade at the Porsche owner.

I used the VCap ODAMS for the crossover mod.  In fact I use those caps for a lot of my mods.  They are great for both crossovers and circuits.  Always get a nice positive move forward.  If you already have caps that's great, but just an FYI.

@gkr7007 

I’ve seen all the modification videos. 

  1. Line the cabinet with “No Res” (I gotta guy who has a poop ton of it)
  2. Line the Horn backs with Dynamat Extreme (any auto parts store it’s cheaper than Amazon)
  3. SoniCaps (I actually have some that paralleled up will = what’s on the crossovers.
  4.  Copper Foil and Heavy Gauge Wire Air Core Inductors
  5.  Sit back and “listen to the music”….not the equipment that it’s played on or the boxes the sound is being reproduced out of
  6. Save up for a new Car (long story there)

Again, loving everyone’s comments and ZERO negativity.

We stop and we know we can stop when all acoustic characteristics of sound in our room are well perveived, especially timbre and imaging...

Thats all....

 

The main problem people seem to have with the pursuit of good sound is when to stop.  Many do find a happy level that satisfies them and stop buying gear, but many others seem driven to continue obsessing and spending money endlessly.

I am a type 1 - I reached a point where any 'improvements were trivial and settled in to enjoy my systems.  I will say that the type 2 relentless upgraders are handy for us type 1 people - they are a ready source of pre-owned gear at decent prices.

 

I believe that the best system is the one you can be content with. That said, I would suggest, generally speaking that as an electronics technician who has worked on older audio, video, analog, and now primarily digital gear, that my rule is GIGO, garbage in, garbage out. No speakers can correct for lacking information. That said, it’s a GENERAL rule, if it pleases you, enjoy. I only bring this up for others because it is a general rule in electronics.

Very interesting post thanks!

What most people call " high end " is related often to dynamic and details resolution improvement which is the MOST deceptive perception related to high end upgrading..Especially when the room is not treated really or poorly treated and not mechanically controlled at all...

What you called "high fidelity" of tone and sound perspective is coming from a better TIMBRE perception which is the acoustic CONDITION and BASIS for improving all other acoustical cues in the room..

My system is low cost ( 500 bucks) and because of the control over my dedicated room acoustic i experience a so good sound that i will never need to upgrade...Nobody believe me because of the low cost of my gear...Price tag import more for most people than acoustic science...

Most people dont know what is "timbre" and the "time envelope"of the timbre components and his "spectral envelope" and what are the acoustic conditions for the optimized perception of timbre using the pressure zones dynamic modification and the timing of the first frontwaves with the reflected waves...It is necessary to transform the room for the specific need of a particular type of speakers for your specific ears structure and history...

Most people buy electronic basic gear or very costly one without placing much attention to acoustic...

This is the key error pervading all audio....Underestimating acoustic and throwing money on a 100,000 bucks piece of gear...

I dont needed gear ...Basic one do the job...

I needed acoustic thinking and a dedicated room , and way more than panels, be it reflective, absorbing and diffusing one in a balance way..This is passive material acoustic treatment It takes way more...I needed mechanical control of the pressure zones with Helmholtz method using resonators but also diffusers...I used near 100 tubes of size varying from a straw to a 8 feet one...

I disconnected definitively 7 pair of various headphones type and put them in a closet with my subwoofer...Guess why? they cannot compete with the speakers/room controlled  synergy...

Think about acoustic being potentially like a powerful huge transfprmation of ANY gear system to the sky...

Acoustic is way more than upgrading...

My best to you....

In the distant past I never questioned whether High End equals High Fidelity. And then it has happened to me (in 2002) that I heard a guitar recording (made with my guitar) that my musician friend made (without processing or editing, straight recording, only level was adjusted). I have listened to him play the guitar between my speakers and the recording to compare one right after the other.

I think very few have the chance for such hard core comparison for fidelity, with an instrument I intimately know, and my musician friend, whose playing I have enjoyed for uncounted hours in my lifetime. Plus, unadultered recording that allows looking into fidelity.

Through my system at that time I had no trouble identifying the exact guitar on the recording - after two notes I knew on which guitar he picked for the recording. (He has about a dozen guitars, all with different tones.) My system gave about 90% of the detail level of the actual guitar being played. The tonality was right, the perspective was right, the image projected was same size as the real guitar. The recording proved to be high fidelity, giving me 90% of the original sound. Now, this was through a heavily modded Dynaco stereo 70 - Fostex Voigt pipes - heavily hot-rodded purist all-silver PAS3 preamp - heavily modded Micromega Stage 3 CD player system - al DIY cabling including PCs (all DIY, yours truly).

The "High End" comparison was BAT and Wilson speakers, and I forgot which very high end CD player & transport & MIT cabling - it was SOTA at that time, and the league of the most expensive High End one could put together in that year. What I heard was very striking, and also a tremendous blow to the head forcing a MAJOR reality check and reorientation of my goals. Yes, there was a jump in detail level, but it did not sound anymore like listening to my guitar from the listeners position. It sounded as if I stuck my head within one foot of the guitar (yes, I have done such experimentation with real guitars). The tonal balance was totally askew, and I did not recognize my guitar anymore. If I was asked to tell which of his guitars he played the recording, I could not have guessed it because it sounded like none of his guitars. And the closest pick would have been a guitar that had a distinctly different tone.

So, while it was evident to all that the HE system in question provided a much higher resolution / detail level, it was also obvious that it completely failed at delivering both the tonality and the perspective / spatial balance, and in general, the EXPERIENCE of the recorded actual guitar.

This experience taught me that High End does not necessarily equals High Fidelity.

Since then, I’ve been investigating what is the difference between "High End" approach and "High Fidelity" which we could call "Reality" or "Real World Audio" (hence my moniker.... LOL.)

The key components necessary to provide High Fidelity AND high detail level: no feedback, efficient loudspeakers, as short signal path as possible. The more we deviate from this path, the easier it gets to get ultra-detail&freq range &SPL but at the price of the tonal balance.

To me, tonal balance is essential, and in my experience is the singular parameter that makes or breaks High End to behave as a show host or the translator of reality.

There is a nice DIY mod for  those Cornwalls that really add to their performance.  Involves damping those plastic horns.  Bracing the cabinet.  And some work on the crossover and wiring.  It's a few hundred bucks but it's a good nice positive change.  Don Sachs let me in on it from someone else and brought those Klipsch up to another level.  Look it up. 

In classical economics as defined by Marshall you have come up against the punishing law of Marginal Productivity. One could draw a graph with audio "quality" on the side and $ spent on the bottom resulting in a curve that rose steeply at the start, then flattened to the point there was no real increase for ANY  amount extra spent. In other words you hit a plateau of economic and hi fi reality.

Before he music industry and home reproduction to the DIN 4500 standard crumbled in the face of commercialisation of the digital domain for hedgefund profit, a thriving electronics industry catered for a wide range of needs providing on the whole equipment and listening pleasure that was realistically priced in the mid range.

I suggest you delve into the world of vintage electronics (but make sure you have the services of a good tech!) whether it be 1970s Japanese monster amps and receivers such as Sansui or design led beauties from B and O or Philips from the same era. A Linn Sondek table will still deliver the gods as well as anything looking like a prop from a SciFi movie. Lastly remember the audio chain is only as good as its weakest link. Sticking to one manufacturer for components that have been designed to work together will cut out a lot of wasted time. Audition speakers before buying and place and tweek the room to get the best acoustic. Aim for simplicity. Unless you live in a mansion with a dedicated music room surround sound will be a waste of time. Stuck to two channel stereo. Avoid silly theories such as pre-amps without tone controls - bi-wiring speakers - spikes for speakers - over priced inter connects and speaker cable - valves sound "better" than transistors "full stop" - all digital is bad - you can get good sound via streaming and downloads - etc. etc. Finally the MORE you spend the better it IS! The basics are: if you are listening to the equipment, after setting up which should not take a lifetime, and not the music then give up! 

@rajugsw The exit from my roller coaster ride aligned with the decline of my quality of my hearing.  I became a much more tolerant of imperfection when I couldn't hear the difference anymore.  Now I have 8 cars, and less audio equiopment.  

Your posted resonated with me on many levels.

First, I wrote a long and passionate post about a week ago in defense of Bose 901s and Bose 901 owners.  I hope you had a chance to read it.  I also wrote a similar post recently in support of McIntosh.  I'm a bit of a speaker geek and received a patent for the Open Line Source speaker back in 1990.  I/we are currently involved in performance mods and had suprisingly good results with a pair of 901 S1s.  In addition to some serious "tweaks" the speakers, we also applied some "high end thinking" to the crossover.  If you'd like to compare notes at some point, I'll be happy to share our approach and results.

Cornwalls:  I have a strong emotional attachment to these speakers.  I become a Klipsch dealer in 1982. When unloading our first shipment off the truck, I was in the process of taking a Cornwall from the truck to the ground by myself when I felt a severe pain in my back.  My immediate impulse was to just let go and let them hit the asphalt.  Then, I remembered how much money I had in the speaker and gingerly took them safely to the ground.  In the coming days, I was in agony.  At the age of 31, it was my first realization of my mortality.  I had an injury that wasn't going heal on its own.  I have the Cornwalls to "thank" for this life lesson.  We continue to do Klipsch performance mods.  We know "stuff" about Klipsch speakers to make them sound better.  I know there are popular kits out there that do a good job.  But, I like the draw the analogy of spending $4k for a turbo upgrade on your car and driving around with the parking brake on.  We start by making sure the parking brake is disengaged.  If you want to compare notes on Klipsch performance, we can compared notes on this as well.

A few years ago, I removed my (really good sounding) modified "industrial look" separates and replaced them with amp/preamp brand that I had aspired to own to my entire life -- McIntosh.  I'm sure your M50s are a great choice to drive the Cornwalls.

I haven't messed with H-frame subs.  Sounds interesting.

Thanks for the post.  Got my wheels turning.

what do you think lightning strikes cause?? 

In my world lightning strikes are different from power surges, which are caused by the power company. One way a power surge can occur is if there is an interruption of power, the magnetic field in the power transformers upstream from your house collapses. When this happens, the transformers put out a very large voltage (this is the same principle used to drive spark plugs in a car). Because of the load on the transformers the surge might only be 50-60 volts.

A lightning strike by comparison will do well over 1000 volts! So I draw the distinction in that manner.

But it sounds FANTASTIC...You can't believe 8 watts into KEF LS50 Metas would even work, nevermind sound like it does.....Something is wrong with the whole High End HiFi picture.....

@rbertalotto 

Not really: there is a reason Nelson Pass named some of his product 'First Watt'. Most of the time that's all the power most people are using- the extra power is for peaks (most of the time). If you have a good clean first watt, you can do a lot with that, and this has fueled a great deal in high end audio!

Again- high end audio is driven by intention, not price.

(If you worked with that little amp to solve its noise problems, I suspect it could be sorted out.)

Recent "Law Of Accelerated Returns" thread presents opposite argument to this. Perhaps each of us reaches a certain peak, at this point we're either motivated or stimulated enough to seek the higher peaks or turn back since the climb already undertaken has been taxing enough.

 

Law of accelerated returns says cost/benefit ratio all in favor of benefit, law of diminishing returns say costs quite high compared to benefits, law of no returns says costs far outweigh benefits. The last being gist of this thread.

 

I've been in all three camps at various times in my audio journey. Spent most time in diminishing returns camp, well over twenty years here. Only recently have I entered accelerated returns camp, the sound quality of present setup has finally reached the peak where live non-sound reinforced music, best sound system ever heard and sound quality of my dreams live. The difference in height between that peak of diminishing returns and accelerated returns is significant.

I spent way too much time and money during the shutdowns having lots of fun buying and selling and researching. 

Sometimes (no just about all the time)....The fun for me is in the research....AND THEN the HUNT!......Trying to find that one piece "everyone is raving about"....Ordering it, waiting for the FedX/UPS truck sittying on the sidewalk, Unpacking, Hooking it up, hating it (can't understand what everyone was raving about), returning it......Can't tell you how many times that happened in the two Covid Years......The UPS store knows me by name!

 Last week I bought a little, four tube amplifier kit of a fellow on one of the audio classified sites for $100 (s5Electronics K-12G)...Built it in about 2 hours....Hooked it up and compared over a number of days to VTA ST120 Dynaco clone and First Watt F5v2......The amp is horrible. Buzzes like a swarm of bees and hums a tune I don't recognize(if you put your ear up to the speaker)....But it sounds FANTASTIC...You can't believe 8 watts into KEF LS50 Metas would even work, nevermind sound like it does.....Something is wrong with the whole High End HiFi picture.....

@realworldaudio thank you for that detailed explanation. I sincerely appreciate your time to respond. Are you the same Real World Audio on Youtube?

Thanks everyone for your words of Wisdom (not joking actually). I had a friend over this afternoon (the owner of the R3’s actually). He couldn’t believe how much Bass the Speakers were generating. I put a very basic EQ profile into the miniDSP as I described earlier. It accentuates the 40Hz "room boom", but only when called upon. You see I also have 50Hz & 60Hz room nulls that I boosted with a sharp Q filter so that the lower midrange wouldn’t be muddy as Hell.

He liked the sound they made in my room but I told him, previously, never had to EQ things. Both the Jolida 3502p with KT150’s & the Orchard Audio Ultra Amplifiers had enough juice and were tuned by their designers with flat responses but with enough power/current to extend the highs while maintaining those booming lows.

The ICE Amps on there own have a flat response but they are more suited as Subwoofer Amplifiers. I knew that when I bought them 2 years ago. A little EQ never hut no one....right ?

Oh, the power surge/brown out ? Power Company did it on 2 consecutive Saturdays. I wasn't home for the first one. But I was for the second one. Nothing to do with lightening or bad weather. This after all is Phoenix, AZ in the "Winter".

The fuse in the BAT should have blown ! When I bought it, I never checked what fuse was in there. Why would I if there weren't any problems. I don't use a power "conditioner" cause I do hear a slight bit of noise when I plug my Stereo Equipment whether the Panamax Box or the Monster Power Bar. .

A power surge can knock out your whole house and even the entire block with every house, business, and utility infrastructure!

 

 

A power surge should never knock out anything more than a fuse.

 

Well, @atmasphere  what do you think lightning strikes cause??  😀

Last rainy season lightning took out two unprotected pieces of gear.  One was the cable modem (no protection on the incoming coax) and another was a laptop, which was left charging overnight and I forgot about it. Everything else which was fully protected survived. 

@moofoo For me a big part of growing towards "natural sound" was going for higher and higher efficiency speakers. The common view of high efficiency speakers is that they give you "more SPL for your watts". However, there's something fundamental happening: a 112dB/Wm loudspeaker gives us the same dynamic resolution (dynamics shading / range) as the live event does. The lower we get with loudspeaker efficiency, the more compressed the reproduction is, and as a consequence it looses "life" compared to the real instrument. A loudspeaker with 102dB/Wm is although considered ultra-efficient but it already imposes 10dB of dynamic compression to what is encoded on the recording, hence, it will already sound a little less live (=more compressed) than the instrument it reflects. 10dB compression in itself is already significant, as the dynamics has been compressed 10 times in power. Sadly, that is on the verge of what is achievable today with a loudspeaker cabinet the size of a healthy refrigerator, and it's about the limit what a normal person can squeeze into a large room.

However, looking at an average loudspeaker today of reasonably high sensitivity of 89dB/Wm, we get a whopping 23dB of dynamic compression, that is, we get 0,5% of the actual dynamic range! Even worse, most of the current high end loudspeakers roll today around 83dB/Wm (most of the sensitivity ratings are vastly inflated - when you see dB/2.83V/m & low impedance dip, that's the warning that the dB/Wm is often 5-6dB below the dB/Vm spec.) With 83dB/Wm there is a 29dB dynamic compression, that is, the information is coming at an almost x1000 energy compression. This has two consequences:

1. it will not sound like the real instrument - will have less life, radiancy, freedom in the sound. Even though all the textural information is there, it seems to be "resolved", and images sharply, but the dynamic information is severely compressed. Changing volume does not alter this fact, just changes the SPL at which this compressed material rides.

2. When set to same peak SPL as the real instrument, it will sound way more dense, forceful, "tight", "heavy", and tiring as to achieve the same peak SPL, the median energy output has to be much higher. The sounds that would have been soft are now compressed into the loud band. This makes sounds in the middle of the dynamic range more pronounced, and thereby the listener does experience it a an enhancement of sound quality by hearing fainter sounds more prominent. Yet, the very soft part of the dynamic range is lost, and the very low detail level is gone. This is obvious for experienced listeners, and is perhaps the most important aspect that distances real music instrument sound from recorded / played back compressed material.

Cheers,

@realworldaudio - I really enjoyed your post. I love acoustic guitar and play as a hobby. Recently I found myself thinking my system sounds really good with acoustic instruments, to my ears anyway. I have a couple different amps and preamps so now I can really experiment based on your post! I have wondered about volume levels, i.e. if someone were playing acoustic between my speakers, would my system sound real if the speaker volume was the same as the guitar? Thanks again for the post!

Personally, I'm out on the limb sawing it between me and the trunk to see if I can levitate....*G*

It beats the usual pursuits and nobody else seems to be trying to do so...reasonably assured that I won't croak in the attempt anyway. *L*

(If one asks '...wtf are you up to?', I'm good with that, too.  Stealth is fun in it's way...) 😏

I can relate to what the poster is saying.  Over the last 55 years, I've upgraded my system about 3 times.  Currently I've been on a splurge to create my "final" system. I recently purchased a McIntosh 352 hybrid integrated amp ($5,000 after trading in my McIntosh MA6900 integrated), Bryston BCD-3 ($4,100), Soekris R2R DAC ($1,200), Nordost Tyr speaker cables (purchased used at Audiogon for $4,400 for a 4 meter run),   Synergistic digital cable and interconnects feeding into a Focal 1027 Electra purchased in 2007 at a discount for $5,000, Shunyata power conditioner bought from Audiogon for under $1,000.   Reatively speaking, not an outrageously priced system. My Focals sound great but now this final addiction has me looking at the Focal Sopra 2's at $22k!    I seriously wonder (i) whether I should quit right now with which,  to my ears, is a wonderful sounding system, and (ii) joining a 12-step program for audioholics.

In the distant past I never questioned whether High End equals High Fidelity. And then it has happened to me (in 2002) that I heard a guitar recording (made with my guitar) that my musician friend made (without processing or editing, straight recording, only level was adjusted). I have listened to him play the guitar between my speakers and the recording to compare one right after the other. 

I think very few have the chance for such hard core comparison for fidelity, with an instrument I intimately know, and my musician friend, whose playing I have enjoyed for uncounted hours in my lifetime. Plus, unadultered recording that allows looking into fidelity.

Through my system at that time I had no trouble identifying the exact guitar on the recording - after two notes I knew on which guitar he picked for the recording. (He has about a dozen guitars, all with different tones.) My system gave about 90% of the detail level of the actual guitar being played. The tonality was right, the perspective was right, the image projected was same size as the real guitar. The recording proved to be high fidelity, giving me 90% of the original sound. Now, this was through a heavily modded Dynaco stereo 70 - Fostex Voigt pipes - heavily hot-rodded purist all-silver PAS3 preamp - heavily modded Micromega Stage 3 CD player system - al DIY cabling including PCs (all DIY, yours truly).

The "High End" comparison was BAT and Wilson speakers, and I forgot which very high end CD player & transport & MIT cabling - it was SOTA at that time, and the league of the most expensive High End one could put together in that year. What I heard was very striking, and also a tremendous blow to the head forcing a MAJOR reality check and reorientation of my goals. Yes, there was a jump in detail level, but it did not sound anymore like listening to my guitar from the listeners position. It sounded as if I stuck my head within one foot of the guitar (yes, I have done such experimentation with real guitars). The tonal balance was totally askew, and I did not recognize my guitar anymore. If I was asked to tell which of his guitars he played the recording, I could not have guessed it because it sounded like none of his guitars. And the closest pick would have been a guitar that had a distinctly different tone.

So, while it was evident to all that the HE system in question provided a much higher resolution / detail level, it was also obvious that it completely failed at delivering both the tonality and the perspective / spatial balance, and in general, the EXPERIENCE of the recorded actual guitar.

This experience taught me that High End does not necessarily equals High Fidelity.

Since then, I've been investigating what is the difference between "High End" approach and "High Fidelity" which we could call "Reality" or "Real World Audio" (hence my moniker.... LOL.)

The key components necessary to provide High Fidelity AND high detail level: no feedback, efficient loudspeakers, as short signal path as possible. The more we deviate from this path, the easier it gets to get ultra-detail&freq range &SPL but at the price of the tonal balance. 

To me, tonal balance is essential, and in my experience is the singular parameter that makes or breaks High End to behave as a show host or the translator of reality.

 

Mwinkc,

Hope you allow me to chime in. Wishing you best of luck. It happens to more audio enthusiasts than you imagine. This happened with me who decided to go the route of downsizing. Four years ago I completed downsizing after 38 years of audio binging and I have been successful in keeping the upgrading crave away. It was hard for me but life has been good paying less attention to reaching the audio almighty. Now I am happy with a very modest system and am I enjoying life more than ever listening to the music and only the music. I know, I know, I know, "say it isn't so".  But it happened.     

Well, musicality of sense of hearing is kind a gift. Long time ago my mom and her colleague decided to hire one of the best violin teacher in our area for us, their sons . The teacher performed several special musical hearing tests for us. As I remember the tests were pretty long and kind a strange for our understanding. Based on results my friend was rejected. He’s mom was so desperate, she couldn’t understand the reason but teacher was very strong and steady on he’s decision, keep saying that it’s will be just waist of time for the guy. After that he’s mom hire another teacher for different instrument for my friend, totally unsuccessful, dropped with in the 6 months.. nothing wrong with the guy, we’re still friends he is successful business owner and even more successful wrestling coach, but with zero interest in music or SQ.
