Of interesting note.
On this EL84 there was a power surge as soon as turned on. When the Jensen electrolytic cap went in. No longer. This makes me feel better at least. |
Didn't fix voltage surge but seems to sound better. |
Changed my first power supply cap.
Not the improvement hoped for. So far it sounds bright to me. I am hoping for break in improvement. |
I am going to start clocking in the hours for break in on the Jensen Electrolytic in power supply.
I have some ASC poly caps here to compare in the same amp in the power supply. This will take some time for the Jensen electrolytic caps to break in. Then for the ASC's as well. (some modifications to make work) I even have a Mundorf Silver in Oil still around that could be put in as bypass. From Tempo's site the ASC is ranked higher anyway?
Right out of the box aggressive and have a bright glare on the Jensen. (I hope for big improvement with break in)
I took out the amp yesterday as I wanted to listen to some music and the Duelund/Jensen coupling cap'ed amp stares at me.
Once again it is not as easy as one would think (or at least me) to replace old parts and get some big improvement (at least out of the box) as long as the old parts were working correctly. |
Duelund
Yes I might be crazy. Like I have mentioned before how did some old tube amp pulverize my new SS amp at the start of this thread started my brain thinking and testing wanting to know why?????
One of the things that shocked me the most was the old amp was "dead" quiet. I have 104db efficient speakers and the noise reduction was just astonishing compared to the new SS amp.
I am starting to wonder now about new electrolytics. My formerly "dead" quiet amp EL84 has no idle hum (and did not before) at all with the Jensen electrolytic but a white noise at a level vastly higher than the vintage electrolytic cap. I can hardly keep myself from yanking it out!
Are the new electrolytics packed tighter to make them so much smaller? The old one I took apart a lot of goo (electrolytic) with the paper kind of a gooey dead mass. Are the new electrolytics too focused on size??? (being small) Is the reason the ASC caps are thought so good (power supply) they have liquid around the cap. Is this causing a dampening? I expect so.
On the coupling caps the vintage Vishay's are all dipped in some resin. The Ampohms are not. Is that why the Ampohms are noiser? Is this dampening the resonance? |
Ait
I would not have a clue how to do that! Now when you say eliminate PS caps from the signal path completely? So no PS caps? Are regualar PS caps considered in the signal path? Anywhere to read up on this? |
Hours on Jensen Electrolytic I would guess 25-30++.
When doing the midrange speaker comparison cap test I found the vintage foil in oil to be the second best to Duelund and the difference not huge. (this confused and shocked me)
I once said after putting the Duelund tweeter caps in the speaker I could not believe I was listening to digital.
When the Jensen is in the amp power supply the sound is digital! The noise level is for sure up. Sound tense and dry.
I am of the belief it is the liquid. The vintage electrolytic cap is bigger for the same volume. More liquid? In making caps smaller tighter and no doubt drier is there not a price to pay? If Duelund adds more oil on there wire and claim improvement would not having less electrolytic (goo) make sound drier?
At this point this is one of the biggest differences in caps I have heard. (not in the new caps favour either) Yes more bass but much more noise.
At the begining of the thread I put in Sonicaps in one speaker and left the other vintage foil and oil. My wife came to listen with absolute no knowledge of which was which and was floored how much better the one was. She said that is amazing! You should be thrilled, problem was she was pointing to the vintage foil in oil not the new caps. (with the hours on them)
I think that is why some guy pays $15k for some old amp that may go up in smoke any time. Is it the old electrolytics?
http://www.audiogon.com/cgi-bin/cls.pl?ampstube&1291419107&/Marantz-Model--9-(Original)-tu
Tempo claims that ASC caps beats all electrolyics PERIOD. I can imagine this.
Now what about foil in oil in the power supply? I have already looked at Duelund but too pricey an experiment for me.
As it stands now the vintage goooey sounding electrolytic is going back in and Duelund caps and oily wire everywhere.
I will put at least 100+ hours on the power supply cap to be sure. |
Ait
I am going to have to do some more reading about this for sure as I am just floored by what the first cap does after the rectifier tube! Just unbelievable!
In my opinion this may "the" most important part of the amp?
It actually scares me! No one would know I had several $k in coupling caps and wires. I want to end this experiment early.
This may be why I thought the vintage ASC amp (had a poly plastic tone to it) was the only bad sounding vintage amp I had with a dead feel to it that is until now. |
Just putting on the hours. I can not wait to yank this part out.
Fast, stiff, tense, dry, shrill and noisy. Voices have non human sound frail sound.
Vintage cap slower, lush, liquid and musical.
Coming out early next week unless a huge change. |
Info too come soon on power supply caps.
Searching the net for another test.
Duelund have you ever tried any of your caps in the power supply? |
Undertow
I would really like to know what is in $20k and $30k speakers for crossover parts. My 5k newer speakers had just garbage and the older $5k Klipsch much better. The new speakers had el cheapo electrolytic caps in the crossover. (less than $50 in parts each for $5k speakers)
I am under the understanding that Klipsch new $20k speakers use just dirt cheap parts?
After all the tests I have done I would not buy a set of speakers without seeing the crossover. (at least not anymore) I can not even comprehend it anymore.
It would be really nice to hear what some guys with stock caps in pricey speaker have. I am quite curious.
Is there a correlation of what you pay for speakers and get for parts? I am of the Steen mindset it is mostly (for most companies) a looks or marketing thing. |
Wilson site pics.
A blurred pic showing what looks like poly caps and cheap wire wound inductors with plastic ties to me? Is the pic blurred on purpose?
http://wilsonaudio.com/product_html/maxx_xover.html
Even in a set of $30k speakers what can a manufacturer spend on parts? I often hear 1/6th of retail price???
So wire, drivers, cabinets and all crossover parts for $5k and of course building and any R&D.
Is there really economy of scale in making new speakers? Can the big companies get there parts for a fraction of what we pay? |
Interesting article on Duelund wire.
I would have thought the 2.0 would be much better??? It seems not so clear at least in this guys mind and at 3x the price.
http://www.hificollective.co.uk/kits/pdf/duelund_wbt_interconnect_review.pdf
The reviewer mentions the highlighting that I also feel is done by stranded favouring certain freq. for some reason? I agree your brain trys to connect the dots.
He also mentions that the bass is maybe a little shy, exactly what I though as well in the .5. (but still very smooth and natural)
Oddly enough I keep doing the same thing with the Jensen vs. Duelund VSF in the amp. I keep coming back to Duelund but the Jensen (Copper paper tube) is sharper?
Could be some Christmas gifts coming. VSF Black? Silver wire? Power supply? Hmmmmm. |
I agree with all that you have said Undertow except in the older Klipsch with the foil caps autoformer.
The Klipsch foil in oil were the second best next to the Duelund VSF in the midrange.
The vintage Klipsch even had a iron core wax paper inductor. (wax paper being the key to reduce resonance)
Bob Crites uses just Sonicaps (which are very different from original) and an autoformer and inductor supposed to be exactly the same and charges $285 for AA's. My guess is it would cost around $500+ to even match original with foil caps of equal sound.
I do agree with you though in the sense my Linn speakers used dirt cheap parts around $50 for everything.
I bet if one looks the trend is to cheaper parts in the cabinet all of the time.
My crossover costs (not including parts not kept)
2 Duelund 2uf VSF $167.17 2 Duelund 2uf CAST $334.34 2 Duelund VSF 13uf $535 2 2.5mh Duelund WPIO inductors $437.61
Total x2 $2948.24 Plus 20 feet of Duelund Silver wire .5 $250 10 feet of Duelund copper wire $45
Total $3243.24
I can see why companies are looking cheaper! I love the sound of them but do understand why speakers are not made with expensive parts. Use Linn level parts and save $3200 each pair of speakers. Very inticing when the speakers "look" the same. |
Duelund
Steen had mentioned when he designed those caps with no concern from a board about costs what his focus was. (best possible sound)
I believe we really have two markets. One of speakers built by larger companies with a focus on the bottom line (and not saying that is bad) and what drives it such as fancy cabinets (mentioned by Steen) fancy ads and attractive cabinets of which mine speakers are for sure not and those (likely small numbers) who mostly care about how they sound.
How many times on this thread have we even heard people mention how pretty there cabinets are? It is clear what group is here.
I have said before I feel after hearing these parts that store bought speakers (with mostly cheap parts) are only a starting point not an end point.
I can not even imagine a large company who has paid a $1 or $2 for a cap even looking at caps in the hundreds of $$$ if they are looking at their bottom line?
I am just glad you make them and I can say I have no buyers remorse. (except sometimes think I should have got more CAST, maybe but not less of a crossover) |
Duelund enters high voltage entry level cap.
Is this in response to what has been talked about here? That meaning that the power supply is very important more than previously thought? (at least by me)
Is this new cap for the power supply? |
Micheal does the VCap Copper have any of the coolness of the regular VCaps?
I have not heard either. I know the regular VCaps were thought be double edge sword?
That is pretty stiff competition to be "way way" better than.
I just might have to hear for myself. |
John
I agree with Irish65 in a big way. I have been away awhile and have not read everything but the Duelund inductor shocked me at how much better it was than stock or the North Creek I was comparing as well. (the stock was a wax paper thin wire inductor)
Most speaker use a VERY cheap inductor that has no way to deal the resonance.
My feeling before I heard it was the inductor was not that important after all how much high freq noise could be caused by the inductor?? Boy was I wrong! Lots!
I believe the reason for this is that most inductors are just garbage! Everyone seems to treat this part as an after thought. So a massive improvement from top quality and junk.
I do not have CAST inductors like Irish but if I had the $$$ I would. I have Duelund WPIO. There is no reason not to have CAST inuctors except $$$. In the case of the inductor CAST is just awesome at blocking noise. I have not heard CAST as an inductor just a CAST cap so base that comment on that.
I also agree with Irish on you really go on a thread like this and you can narrow your list but I would buy a few choices till I heard the differnce. Only you can tell what is worth it and what is better.
One thing I did to save money was always buy one cap or inductor first. That is how this started comparing just one Duelund VSF and Mundorf parts. I order the VSF with the idea I am just throwing some money away but let's hear the fuss.
Not sure how much Frederik liked this buying one at time but they are expensive.
You really can not know what you will end with till you hear them.
The key thing in this thread is start with a set of speakers you REALLY like to begin with. I think you may find you are in essence done with trading speakers after that. (so likely your last speakers)
I bought Sonicaps, Mundorf Supreme's and Silver and Oil, North Creek inductors, Jensen Paper in Oil and of course the Duelund VSF, CAST and Duleund WPIO inductors.
What sounds like budget saving idea buying cheaper parts ends up costing more. All of the parts are gone or not used except the Jensen and Duelund parts. All at a loss of course.
When this thread started I was not thinking of blowing a wad on parts!
For example I expect there will be wayyyy more difference in a Duelund inductor and stock inductor than Jensen Copper Paper tube and Duelund VSF.
Tweeter caps is another good area to test as this part really matters as well.
Irish65 I am going to reread you part about series tweeter inductors. I have not replaced mine yet. You have got me thinking about that part??? |
Irish65
I am going to order a Duelund tweeter inductor. After reading your post on the tweeter inductor and the difference I have to see.
I am going to start with WPIO Duelund. I did not change the series tweeter inductor thinking how much difference can it make?
That has been one great thing about this thread what you often think does not matter does.
Only one question what about changing the DCR? I did not find the North Creek 10 guage woofer inductor to my liking. I am not sure how much was caused by the DCR change or it not being a wax paper inductor as the original was and the Duelund I ended up using.
Have you compared WPIO and CAST as tweeter inductors? |
I am ordering just one WPIO. That way if it is not good DCR wise then a CAST would not help either same 12 guage. If it is a huge improvement then hmmmmm? Maybe a CAST? I have a friend with a set of Khorns who would take any of my used Duelund parts.
My current tweeter inductor is a high guage. I would guess more like around 30?
My guess is the Duelund again being foil will sound better.
I have heard much talk about North Creek inductors and they are wire wound. I found them not to be in the same league at all. (woofer inductor) I have a 2.5mh 10 guage if anyone is interested?
I for sure do not doubt you Irish. I could not believe how much high freq noise was coming out of my woofer before the Duelund WPIO went in.
Irish how much Duelund Silver wire do you have for sale? (and why?) |
Irish65
How much Duelund Silver 2.0 do you have? Is it generation 1 or 2?
I have partsconnexion contacting Duelund now on the inductor. I am curious of the Q.
I know the DCR is going to be much less with Duelund.
My current one is .37DCR. Just not sure what this means, sound wise?
http://forums.klipsch.com/forums/t/47.aspx
This thread talks about the various parts in the same network. North Creek actually had the lowest Q. I found them to be noisy so can not argue with this thread.
In fact it says what I have said many times the original parts used decades ago like the wax paper inductors (foil capacitors) were not that bad. Consistently it has been Duelund (and sometimes Jensen) that has bettered the vintage parts but this makes more sense than one would think. Similiar construction but to tighter tolerances.
I am going to have to go back and read my inductor tests. I know when I got the Duelund WPIO woofer inductor in 10 seconds I knew it was a keeper. (wished I got the CAST at the time) |
Tom
I am not sure as to why I liked the Duelund over the North Creek in the woofer inductor. (foil vs. wire or resonant reasons or silk and wax paper) The Duelund by the way was VERY close to the original that was Iron core in DCR. (wax paper) So the speaker did not change character.
Now going to the tweeter inductor I am going to get a lower DCR with the Duelund. Simply a much bigger guage of wire.
I am not to sure though how the North Creek deals with resonant vibrations? (electronic) I know it is not vibration for mechanical reasons as it weighs a ton!
As much as I have said many times about really liking Duelund products there is one I did not care for and that was there old solid copper hook up wire. (no longer in production)
Tempo Electric posted here a long time ago that they did not care for the old Duelund wire wound inductor? So it does lead me to believe there is something with foil??? |
Sorry mine is a parallel inductor.
That is why I did not change it months ago. Just having a brain fart!
I am still curious as to what the effect will be? or just a waste of money? I think not a waste as Klipsch even then took steps in the inductor to reduce resonance. (wax paper) |
Duelund not ended yet!
I have a parallel tweeter inductor coming from you and have bought some Duelund Silver 2.0 from Irish65 for speaker wire. So at least two more tests. |
Duelund it is me. I am just unsure what a parallel part is going to do. (i.e. waste of money?) |
Face
I agree but have been led to believe it is not as important. (why I did not change the inductor before) Does that mean can not hear it or just not as critical?
I guess I will find out.
I have to admit I am very curious.
I have some friends just laughing at the idea of Silver wire coated in Silk wrapped in cotton(which I am excited about) and being able to hear the difference big time. They just laugh! Oddly enough the same friend after hearing my system said "it does not even sound like a stereo" spent many a nights up to 2-4am looking (and bought) (I would get the 4am e-mails) the same gear. He drove up 10 hours each way to the U.S. to get it as well. I told him not the gear but the parts.
I do not think he fully can wrap his head around that though that it is the parts. He really struggles with the idea that 2k (used for sure) for the speakers and 4k for parts after. |
I have been listening for a few days to the wire comparison. It is just against Linn 12 guage which cost around $3 per foot so at Duelund price for Silver x2 it should be a LOT better.
I will say it sounds like two speakers out of phase. Likely caused by resistance difference.
Silver is NOT bright that is for sure. Not sure where it gets that reputation?
There is much less high freq noise or what I thought might have been tape hiss?
Stranded copper favours as it did in the internal wire it's own freq. which is the highs. The Silver sounds much more liquid top to bottom.
There is more tighter dynamic bass. Actually more dynamic across the range.
I do find myself thinking about turning up the treble though. I seen Duelund once selling a really high end tweeter. |
Sorry just learning how to use an iPad.
I expect less noise from the Duelund inductor because of better construction but am curious going from thin wire wound wax paper inductor to foil type what type of change there? After all it is a tweeter inductor not carry any low frequencies? |
I had some kind words from Irish on this thread and how it has helped people. I can say the original intention was there would one guys log on parts (start to finish) I did not think there would be so much great info from so many people or it would be so long.
I just spent so many hours reading on the net before ordering my first parts for testing in the crossover and could not find any on going kind of debate or what the buyer felt about the part after a period of time.
It was a fellow poster on here that got me try a Duelund VSF for the tweeter. I truly really thought I was throwing my money away with an oh well attitude. At the time many people said as long as the uf value was the same anything would do.
I think this thread has if one thing once and for all changed that idea. At almost 200,000 visits it has been seen quite a bit for an obscure subject as speaker parts.
I think we all really owe Steen a great deal. I think even for the ones not using his company's parts he as far as I know he single handily changed the whole notion on parts. 50% of your $ on speakers and 50% of that one crossover parts. (at the time a crazy notion)
When the Silver wire gets here from Irish I will have followed Steen's path almost right to the end. Almost no stranded wire left. (a little in the amp)
Almost no plastic. Just have to get some Duelund IC's some day. |
Wire here in the next couple of days.
Not sure about tweeter inductor? |
Wire in and I will be installing tomorrow.
Long story and I thought a friend who brought it back from the U.S. lost it.
The 2.0 has two layers of cotton compared to the .5 and of course thicker wire.
Anyone know the difference from version 1 and version 2?
Does not have as much smell as .5? Not sure why? Extra layer of cotton? |
Undertow
Mine are for sure the vintage Klipsch with foil capacitors (stock) and Alnico magnet drivers and wire wound wax paper inductors.
I can not agree more that Klipsch not really using anything decent anymore but many companies use garbage parts as well now and often in big $ speakers.
I am not saying changing the DCR will always be bad but it will change the sound. I guess that is why it is called a balancing network and changing DCR changes the balance.
I am curious of the pro's and cons of the Autoformer??? |
Dgarretson I am not sure that the air will come around? Duelund has a signature sound for sure. Or one could say plastic has a signature depends on point of view.
When listening to Miles Davis the wire changes everything.
Almost re-aranging who gets top billing. I can not imagine that Miles was giving top billing to the drummer with the cymbal, high hat and snare drum? This would be putting himself, John Coltrane, Cannonball Adderley and Bill Evans all in the background?
With the stranded copper the piano sounds like in an echo chamber. Just a joke.
Stranded (at least with plastic) seems to favour it's own freq. (the high)
I notice a big difference in dynamics! I assume this is because of the lack of echo? Silver sounds much more alive.
Without a doubt no one can think it sounds the same!
I remember getting the first CAST tweeter cap and being shocked. Soooo quiet and yet clearer? Yet part of me missed the "air". (even the air added by the VSF)
The wire does take getting used too. The highs although maybe do not have the same air are clearer. |
The order is being sent from Parts Connexion for the for the tweeter inductor.
Once that goes in I will have only 2 parts left that are not Duelund (in one side). One cap in the amp and the autoformer.
A friend was by that bought the same speakers etc. He hears the wire difference which I think is very big but he thought it sounded fantastic even before. He did notice more bass with the Silver wire and not as bright. |
Duelund tweeter inductor is in.
It must weight 50x the original one. Not sure what that is going to mean sound wise? |
I have been thinking on the solid silver wire.
Dynamics are greatly improved. Why? I think the plastic coated stranded wire slows the low frequency more. Dynamics are of course affected by low frequency more than highs.
Can thin stranded wire carry a low frequency signal as well? I do not think so. I can really hear bass tone that I could not before. The stranded seems to chop it up.
For a while I have liked the solid silver wire sound better. More relaxing to listen to.
Tomorrow I am installing the tweeter inductors. I expect to |
The Duelund tweeter inductor is installed.
The construction is of course very close to the vintage that was there. Both are wire wrapped around cardboard. coated in wax. The vintage is solid wire and very thin guage. The Duelund is of course foil wire and heavier guage.
The Duelund is MUCH bigger and heavier and better built. The vintage is not as tight with the wax maybe allowing some resonance? I bet the vintage though is still better than most any inductor built today as at least it is wax paper. (some way to deal with resonance)
The initial sound impression is the Duelund sounds hotter. The lower DCR? (not sure) I was thinking it would be quieter (because of better resonance control) more laid back and was not sure I wanted to go that way. It is the opposite meaning more signal to the tweeter.
This may make sense as the Duelund solid wire (used internally) cut the high freq and did not sound quite right. (to me)
This is a parallel tweeter inductor and my initial thought is these parts did not matter so much, yet the sound is very different! Not sure yet what is all means but for sure very different. So these parts DO make a difference. It sounds like more signal getting through which is what the woofer inductor change sounded like.
Was the thin vintage wire cutting back the signal? (I think so)
I was up buying connectors from the local stereo store for this job and I can not believe how far my system sounds compared to store. $10k systems sound literally like clock radios. |
Jburidan
Lower resistance in the tweeter inductor maybe. I should measure both to be accurate.
In the woofer the (thin wire) iron core wire wound and Duelund Air core were almost exactly the same.
I changed that part with less hesitation because of same DCR. |
Undertow you must not be using the simple "A" or "AA" in your Klipsch? There is no resistor at all. Very basic circuit. The "A" even simplier.
Undertow I do agree with Duelund being "transparent". They seem to get more signal though whether it is the caps or wire or inductors.
I really should measure the two inductors to see. I am trying to get the measurement off the vintage. The Duelund of course is in the speaker. |
DCR is flavour changes and once I get to that then I will be done. I only want quality improvements. (which I have got)
The friend who was over listening (and buying my old speaker wire making room for the Duelund Silver) owns a set of Khorns think both sides (of mine) sound amazing. (his are just stock) To me the Silver Wire makes a big difference.
I am getting near the end though and I know it. Changing the parallel tweeter inductor was one of the last parts not Duelund.
I would say to anyone wathcing this thread that parallel parts do not give the same Wow! as series parts. They affect the sound at some %, just not sure how much compared to series parts. Maybe a guess later?
Even going from a Duelund VSF tweeter cap to CAST had me put my ear to the tweeter to see what was going on. (big difference) Nothing like that with parallel tweeter inductor.
Chris at parts connexion looked over my schematics and said not to go crazy with this part. Good advice.
|
I might have found my first Duelund part not working in this application?
The inductor sounds bright and agressive. I am going to check some tubes to make sure all is Ok but just changed power output tubes not long ago. The inductor makes the speaker much louder than the other and not a nice loud.
The last time I changed the DCR with the North Creek in the woofer it did not work out well at all either. DCR from what I have seen is not something to mess with. Even a better part will not sound right? |
Duelund out vintage back in and much better.
These parts make a BIG difference, meaning parallel.
Play with DCR like playing with fire. |
I am trying to get an accurate measurement of the two but do not. The Duelund is somewhere around .1 DCR a little less I think. |
Well Duelund? If you see this could you post?
Is DCR something that could be said not to mess with? Twice I did and both times not good results assuming the Duelund is of different DCR. |
Will do that Micheal. Likely this week on crossover pics.
They sound wayyyyy better than stock Lascala's.
Interesting on the Alexander's. I would have thought them not to sound as good as VSF. In Steen's writing and making the VSF he talked how they needed to be made by hand. Not sure why?
CAST are amazing very low noise caps. Please post what you think after. |
Just back checking strictly Silver Wire. The bass is the biggest difference. Much tighter with Duelund. The stranded plastic gives a mushy droning sound. There is a for sure echo with plastic.
One question I wonder though is the cost of Silver worth it? Why not just flat copper, Duelund? This might be a much better cost option for most people.
This drone/echo in my guess causes the big difference in dynamics in the two wires.
Is this the technical equivalent of wearing plastic from head to toe? We would heat up really fast! There has been many fans of cotton. Is silk just one step more? Where does the heat go with plastic wire?
I am not sure but would like to hear cotton wrapped solid flat copper. I bet you are a very good chunk of the way there at much less cost?
Is there actual numbers on heat retention of plastic vs. cotton vs. silk. I know regular people wear cotton not silk. |
Hi Tom
What is Sistrum Sp101's? |
Thanks Tom Not to be noble as I for sure started with a closed mind. It was hearing a full signal chain that was vintage tube amp and foil capacitors speakers and amp that made me realize things were not moving forward. I was quite shocked.
Mostly I did not understand why?
I do now. Follow the $$$. Business always looking to make things cheaper and I do not blame them. Charge as much as possible and give as little as possible makes for happy shareholders.
I was always thinking name brand big $$$ gear now more of a concept. Simple crossovers with high quality parts.
I can not even imagine buying an amp or speakers without knowing what they are using for parts. Yet much expensive gear is not sold on the parts quality? |
Jburidan
I do get things from both sides. I am very glad I bought many of my parts before the prices have went up so much. The sound is fantastic but I would not want to make a business case for using parts of such cost. I should total my parts today but likely $3k per speaker in wiring and crossover parts. My old stock speakers would total $20-30 per speaker in crossover parts and wiring. If I was in the business??? Using the 6 to 1 ratio meaning $3k of parts would need $18k per speaker extra at retail.
Is it me or has Duelund raised prices again? I have to go through some old bills. On that note has anyone tried the Alexander line? I have one pre-amp cap in the one side that is still a Jensen Paper tube. The Duelund Alexander is cheaper than the Jensen. |
Tom Not sure what you are saying? Are you talking about the Duelund inductor? or something else or everything? Not hard at all to hear one speaker compared to the other? Mono recordings.
Both speakers are still hooked up? Much tougher to do from memory, I think. I think at fist of course we hear change but is it better? After a long period of time hearing both speakers the newness wears off and you really know if you like it better.
I think buying gear in the store on a 1 hour demo is crazy!
If one changes both channels you are going by memory back and forth. In the beginning I kept one speaker stock and the other changed with new parts. Better was REALLY easy to hear at times not so at others.
Yes there are image issues for sure. When you have one speaker with Duelund Silver wire and the other with stranded copper plastic they almost sound out of phase.
This can be a difficult test. |
