Synergistic Red Fuse ...


I installed a SR RED Quantum fuse in my ARC REF-3 preamp a few days ago, replacing an older high end fuse. Uhh ... for a hundred bucks, this little baby is well worth the cost. There was an immediate improvement upon installation, but now that its broken in (yes, no kidding), its quite remarkable. A tightening of the focus, a more solid image, and most important of all for my tastes, a deeper appreciation for the organic sound of the instruments. Damn! ... cellos sound great! Much improved attack on pianos. More humanistic on vocals. Bowed bass goes down forever. Next move? .... I'm doing the entire system with these fuses. One at a time though just to gauge the improvement in each piece of equipment. The REF-75se comes next. I'll report the results as the progression takes place. Stay tuned ...

Any comments from anyone else who has tried these fuses?

almarg ...

I turned the CD player off before going to bed last night. Turned back on this morning at 9am.  Still amazing in every way.

Charles ...

I hope the blacks turn out well for you. They are amazing. 

By the way Charles ... how would I contact you via your Email or PM? I have something for you. 
Oregonpapa, 
Based on your description of the Black fuses impact, if I have the same results I'll never be able to leave my listening room. 😀😀
Charles, 
Al,
Well I suggest that Oregonpapa could put the Red or stock fuses into his CD player, listen and observe if there are changes, and if so what are they.  I replaced the SR Red fuses temporarily with my previous 20 fuses to compare. Unequivocally the sound quality and sheer musically is noticeably diminished with the SR Red fuses removed, very stark contrast. As I suspected, the Black fuses needed sufficient burn in time.
Charles, 
Oregonpapa, glad you have obtained such outstanding results with the black fuses. A question I would ask, though, in all sincerity, is how do you know that these findings were not primarily caused by effects on the player itself that might have resulted from being operated in repeat mode 24/7 for several days?

Best regards,
-- Al
 

Hello again, Guys ...

Good news! After leaving the CD player on repeat 24/7 for several days the two black fuses in the player have finally broken in. Here's what I'm experiencing:

The "pinched" and non-musical artifacts of the unbroken in black fuses are completely gone. What is left is a totally new experience in transparency, focus, air, tonality and realism.  The RED fuses, as good as they are, are now relegated to the toy box.

How does one describe the sound of "nothing?" 

In a word ...  the red fuses are veiled in comparison to the blacks. Hearing these broken-in black fuses over the red fuses is like hearing a fully  broken-in red fuse over a stock fuse. Its that significant. No bull. I could have never imagined that such realism could be attained in one's living room from red book CD's.

Both Charles and I have written about the "layering" effect of the red fuses that is so attractive. Well, forget about "layering." I'm now convinced that that "layering" effect is some sort of distortion, even though its quite remarkable in its own right and fun to listen to. With the black fuses, the effect isn't so much the perception of "layering," but more like each instrument/musician has an actual place in the room.

I've heard transparency from the black fuses from the get-go, but when things snapped to and really became focused during last night's listening session that transparency was drastically improved ... along with even more musicality and emotional impact than was experienced with the red fuses.

Charles ... you are going to love these black fuses. Just wait until you hear Monk!

Call me a nut case (and I'm sure wolf-garcia will *lol*) but during last night's session I was so taken by the music that I actually got up and started dancing between the speakers. It was just me and the band in the room. Good grief! I couldn't stop smiling. Head bobbing and toe tapping. The music was back!

I know many of you have the Clapton Unplugged CD. Well, Eric Clapton was in my living room last night. I've always enjoyed that CD ... but this was live, I tells ya ... LIVE!

Here's the bottom line. Get the SR Black fuses if you want to really hear what your system can do. Keep in mind though ... you have a significant break-in period ahead of you. During the break in period, you most likely will not enjoy your system, preferring to watch the news instead. If you have the patients though, you 'll be in a position to enjoy your system as never before.  In other words, don't expect anything until at least the 70 hour mark.

Thanks go out to the folks at Synergetic Research for a stellar product and to highend-electronics for their stellar service. Betty and Alfred ... you folks are the best!

Robert, my fellow local audiophile, also known in these parts as "Mister Golden Ears," will be coming over tonight for a listening session. He's going to be blown away. Stay tuned ... I'll give another report tomorrow.

Happy listening guys ...



David, 
That's quite an endorsement of the Black fuses impact relative  to the Jadis amps versus  your 45 SET. I should have mine  in about a week. Given your system makeup I know the  resolution is very acute . This will permit you to easily hear and distinguish sonic changes.
Charles, 
Charles1dad:
Still experimenting with two of the three systems. The BLACK fuses are definitely directional in sound in my systems. At least at the power cord application be sure and try both directions. Put one fuse in at a time and allow it to settle in for 24hrs of play before the next fuse.

I just listened to the Teresonic speaker, Type 45 tube Amp, Antelope DAC system affter the system has been on 24 hours.

Turning the DAC volume up from zero sound to 85% , the music filled the room as never before. There is now a better sense of fullness, detail in instrument location and vocals, and most importaintly emotion.

This is comparing the Black versus RED fuse. A much bigger difference in sound improvement than when I went from the Jadis amp to the Emotion Type 45 tube amp!  A bigger change than any tube rolling change I have done.

So in this first system evaluated BLACK fuse > RED> stock fuse.

I do not ever want to go back to a stock fuse.

To all the non Synergistic Research fuse users reading, I urge you to give yourself the present of a BLACK or RED fuse. Try one and send it back if not happy.

David Pritchard
Charles, mmm, you are going to compare the red's vs black's? , if so,  I look forward to your impressions,  and appreciate your efforts. 

macdude,

I believe the Red vs Black fuse preference is going to be system/component(and listener) dependent. Not earth shaking news
I realize. Sometimes when an audio component/part is designed for "ultra" detail and resolution, musicality and emotional connection can be sacrificed. It doesn't always go this way but there's a fine line of trade offs most often. I notice this particularly with speakers. I'll see which direction things go when I get my Black fuses. If I prefer the Reds,the Black fuses will be returned. I look forward to hearing the comparison. I can honestly say that in my case the Reds improved transparency/clarity but also increased the emotion expression/ musicality/organic aspect as well. That's usually easier said than done.

Charles,

I prefer the Red over Black in my DAC for the same reasons oregonpapa mentioned. The Red is just more involving and fun to listen to.
Hi Charles,thanks for your reply. Don't get me wrong,I do appreciate this thread. I am just trying to soak it all in. How a single fuse can make so much of an impact on ones sound system is beyond my comprehension. But,I am here to learn...I want to thank everyone for their time. Please...carry on.

Hi aolmrd1241,

I think there's been an  abundance of common sense provided on this thread based on actual listeners experience with their systems.

The point that's been made repeatedly is , simply try and hear for yourself. The beauty of these fuses is the simplicity of their use. Pop one in, take it out and compare with another. Listen for a while in one direction, reverse direction and listen again, very easy to do. Afterwards determine if you did or didn't notice/hear a difference. Results may not be uniform amongst all listeners.


All I can report is what I hear with various fuses in my components. They go well beyond subtle but fall short of "jaw dropping to the floor". I relate to Oregonpapa's written comments because my listening impressions are nearly identical to his. This is as easy as rolling various tubes, yet the potential change (of fuses) is greater in some cases.

Compared to cables and many audio products the premium fuses are inexpensive yet yield very noticeable improvements. This has been my experience and I'm very happy to have them. No doubt YMMV.

Charles,

On the Subject of Fuse Direction.

The synergistic Research Fuses are Quantum tunneled in one direction-
from the "S" of the word Synergistic  towards the "h" in the word Research. So at least this corresponds to the arrow of some other fuses. You want Current to flow from the capital "S" towards the other end of the fuse where the last letter "h" is.  
So on some fuse holders ( like the tray type holder next to power cord connectors) , it is easy to figure out the "hot" side and the "neutral" side and put the fuse in in the optimum position on the first try. The other spots one has to experiment for optimum results.

I hope this helps.
David Pritchard
Fascinating Fuse thread.

The problem I have is I can change nothing and things may still sound subtly different to me day by day, listening session by listening session for reasons unknown.

But the differences are subtle and seldom ever affect my end enjoyment. I suspect my own mood and perhaps mindset of the hour to be a factor especially when it comes to any emotional response to what I hear.  "Dammit Spock,  I’m a person not a listening machine." Probably a good thing.

I do not have time to dabble with fuse directions normally. If there was a problem to start with and I thought it might be that, I probably would. but I can’t even account for how things that vary regularly out of my control like weather, air pressure, humidity electricity etc. are affecting what I hear exactly at any particular time versus another.

Or how can I even assume my gear always works consistently and that there is not some natural audible variation over time? There is a lot of complex technology in these toys.

So I just throw in the towel and be happy I like it as much as I do regularly. Not the "audiophile" way of thinking I’m sure.

I guess if you flip or change fuses enough with enough a/b tests the results become obvious.
I’m not sure we don’t already have an answer to the whole wire and fuse directionality issue. In fact we hd the nswersgoes about 25 or 30 years ago when cable mnufacturers first began putting arrows on their interconnects and other cables. And how do they know which way the arrows go? They know because they have done the experiments and found that one direction - as the wire comes off the final die - or as the wire comes off the big spool - sounds better than the other. It’s not really all that subtle. Anyway, once you find out the orientation of the wire as it comes off the spool that sounds best as a manufacturer you simply keep track of the manufacturing process of all future wire, even the wire for fuses. If you are not manufacturing the fuse yourself as the manufacturer but modifying a stock fuse you simply don’t put arrows on the fuse and let the customer do the listening test. For interconnects and other cables or even hook up wire it’s ridiculously simple to keep everything straight. It’s also rather easy to eliminate the contact issue from the equation. Not that the conract surface isn’t an issue. Any old fuse is directional, even stock fuses respond well to flipping them.
I’m wondering if any of those who have experimented with fuse directionality have tried simply removing a fuse and then reinserting it in the same direction, but such that it is rotated through a significant angle (such as perhaps 180 degrees or so) about the axis corresponding to its length. Or perhaps simply removing it and then reinserting it without any apparent rotation.

The point to that experiment being to determine if the differences that are perceived may simply be due to minute differences in the physical contact between the fuse and the contacts on the holder. While that may seem to be an unlikely explanation for differences that may be perceived and attributed (or misattributed) to directionality, from a technical standpoint it strikes me as nevertheless being a less unlikely explanation than the essentially infinitesimal differences in various parameters that have been reported to have been measured between the two directions in a couple of papers that have been published, for example, by HiFi Tuning.

Of course, even that kind of experiment would not rule out the possibility that other effects might be in play, such as sonic differences that are sometimes reported to result from simply turning a component off and then on a few minutes later.

Regards,
-- Al

electrslacker:

When I face the VAC from the back there is a fuse holder that pulls out from the IEC on the power supply. The correct orientation for the fuse to be inserted was left to right reading RS A4T. In other words backwards worded left to right.

Gwalt

Okay ... Thanks for the suggestions, guys. l'll try flipping the fuses tonight. In the meantime, they continue to burn in with the CD player set on "repeat." 

While I'm at it, I want all to know that I'm  not trying to disparage SR in the least here. I think SR has come up with a fantastic product, evidenced by the raves from most here on the RED fuses. All I'm interested in is getting the most musical enjoyment out of my system (and investment). I really WANT these black fuses to succeed. As I've stated in several posts now, they show a lot of promise in various ways. I'm just looking for that same presentation provided by the red fuses ... in spades. 

So far, I have heard exactly what Charles describes in his assessment of the red fuses when I had the reds in the CD player. Not there yet with the blacks. I'm keeping hope alive.

Stay tuned ...
"Question? If AC changes direction 120 times per second or 60 cycles per second [60hz]... how then can a change in fuse orientation make a difference in sound quality if there is a constant cycle change in the flow of current? Am I missing something here?"

The current doesn't carry the signal.  Even if it did we only care about the direction toward the speakers.  We don't care about the other direction.

Mitch wrote,

"Geoff, I have 4, 10A fast-blow fuses in my big amp. I have a better chance of winning powerball than getting all the directions correct at the same time, and there is no f’in way I am going to sit around and try listening to every permutation."

I have some good news for you. The odds are pretty good are 2 of them are already in the right direction. You just have to figure out which ones they are. ;-). In fact statistically the odds aren’t terrible that all 4 are already in the right direction. A lot better than winning Powerball.

koestner201 posts01-26-2016 9:18amYes, Mitch is right! Why can't SR print the best direction on the fuse? Are they unable to keep them in line during manufacturing? Let's hear from all the users who have an opinion about the correct direction, and tell us what it is.

I think it's on SR site ... direction is how you read the label on the fuse.  
Galt
Does your VAC have fuse holders that push in on the back?  If so, what does "backwards left to right" mean since it seems like it would depend how you held it?   I'm kind of dense.

Thanks

Charles:

I agree with your post and is essentially my point. it becomes system matching with just one component out of place. I am going to put more time on the REDS down the road to see if there is any improvement. I have heard the difference in reversal and it was clear that in the VAC the wording should be backwards left to right. My preamp. is on 24/7 during the winter months.

As for now I installed the beeswax fuse last evening and will report what i got down the road with more time.


Thanks,

It's simple enough for me to reverse the fuse direction and just listen. Either you hear a meaningful difference or you do not. I do hear a distinct  change(but not drastic )  in the sound. If you don't  then just leave things as they are. 
Charles, 
Geoff, I have 4, 10A fast-blow fuses in my big amp. I have a better chance of winning powerball than getting all the directions correct at the same time, and there is no f'in way I am going to sit around and try listening to every permutation.  The amp manufacturer used Hi-Fi Tuning fuses in the amp, and showed me which way to orient them based on their arrows and the direction of electricity flow.  If the SR fuses had an orientation indicator (i.e., arrow) then I would know how to orient them.

If SR is going to charge $100 bucks for a fuse, it seems they would take the time to test which direction their fuses sound best and then label them.  I am not saying they should test every fuse but, IF this direction thing is true, there must be a reason they sound better in a certain orientation and it must have to do with manufacturing since the parts at each end are the same.  So, what is left, wire direction, which end gets soldered first, which direction they run their 2,000,000 volts of Quantum Tunneling electricity, what else?  If SR can figure out which of those things affects directivity, then they would know which direction to paint an arrow on the fuse since they are all presumably manufactured in a sequenced manner.  Some might say the absence of an arrow on their fuses indicates they think the orientation issue is BS.  OTOH, watching audiophiles fumble with the direction of fuses probably gives them a laugh or two.
I agree with changing the direction of the Black fuses prior to mixing them with the Red fuse.  Oregonpapa I value your listening impressions, we share the same musical priorities. Audio products that diminish rather than enrich the emotional connection  with music aren't for me. It will be very interesting  to see how the Black fuses evolve. 
Charles, 
How many combinations of directions for two fuses?  

First fuse in WRONG direction, the other in WRONG direction.  

First fuse in RIGHT direction, the other in WRONG direction.  

The first fuse in WRONG direction, the other in RIGHT direction.  

Finally the first fuse in RIGHT direction, the second fuse in RIGHT direction.  

POP QUIZ: How many combinations for three fuses?

David,

Might be a good idea to have a short listen are get the fuses correctly oriented before breaking and leaving them to further burn in for the weekend.
Oregon, I think you should turn both blacks around before you mix in a red. It is best to evaluate a directional change as a single variable before you confound your trials with reds that may also be directional. You are providing the first account of the blacks--they may be more directional than the reds, which to me, sounded so good, I did not want to turn them around, and I have three applications in which to try turning. They just sound so right where they are, I have not turned them. It seems we don't know enough about the blacks in this respect. 

David ...

You gave me an idea for tomorrow. I'm going to swap the RED fuse in the phono amp for one of the BLACK fuses in the CD player in the morning. There's still something that's not right with the two BLACK fuses in the CD player. In the meantime, the CD player remains on "repeat" overnight again.

The black fuses show promise, but so far compared with the red fuses, the presentation is boring. What they are doing reminds me of a system I heard years ago. It consisted of stacked Quads and really good tube electronics. The owner was totally into transparency first. Yes, his system was one of the most transparent systems I've yet heard to date. Upon initial listening I was blown away. But ... 30 minutes into the listening session I was thinking of how I could gracefully exit his home. 

I heard another system one time that retailed for over 200k. The owner kept emphasizing how well he "got the rear corners of the stage."  I kept thinking ... yes, but where's the emotional connection to the music? 80 grand for a pair of speakers and another 150 grand for solid state electronics ... to get the rear corners of the sound stage? Not me .. I want to hear Sarah Vaughn's chest and throat. I want to hear the natural tone of a soprano sax. I want to hear the beautiful resonances of a bow being drawn across a cello. I want to be made to hold my breath while the music just flows over me in waves of beauty. 

The black fuses so far are leaning toward audiophile-ism. they ARE improving, but man, this is one hell of a break in period. I'm going to continue working with them just to see if they finally come around to the musicality of the red fuses. It would be wonderful to have the transparency of the black fuses with the musicality of the reds. We'll see.

Charles' last post hit the nail right on the proverbial head.

 
The Synergistic BLACK fuses were installed in the Antelope DAC (uses two) and in the SET Type 45 tube amp. Speakers are Terasonic high efficiency. Since the DAC has a digital volume control, I will leave the system on but no sound from the speakers until critical listening this Saturday. That way I do not listen to any break in changes and  temporary impressions that may cloud my listening.

I may find I like an all BLACK system, a combination of RED and BLACK or an all RED ! 

I plan to have FUN and enjoy listening to the sonic changes.

Interesting thoughts.

I suspect the new phase of A/B-ing Red-Black-Red-Black we’re entering will be more problematic than the revelatory first hearing of the Red. I think the vagaries of A/B occur because we tend to overlay what we’re hearing with what we previously heard, so instead of being an insightful measuring device, the brain is singing along, blending memory of sound with what’s being currently experienced. It’s also true that our minds make us conscious of something newly perceived, but can ignore something that fades because memory can fill in what fades. If we’ve been hearing “The girl with colitis goes by”, but the Red reveals the lyric is actually “The girl with kaleidoscope eyes”, then we’re going to hear “kaleidoscope” regardless of whether we go back to old fuse, or forward to the Black. So what we hear is often cumulative, and what is lost is often ameliorated with memory. I think this is why A/B tends towards “can’t tell the difference” when switching back and forth.

In my case, my initial perception was that the Reds were presenting more information through a clearer window, which turned singers into imperfect humans—sometimes struggling, instruments with more of the discordant overtones, and percussion with more “hitting something hard with intent.” I can understand why some systems would portray the effect as “lean” or “cold,” but I think most systems are warmer and more resonant than reality. I really couldn’t go back to the less revealing sound, but I was aware that in choosing the Red, I was choosing a more naked portrayal where I perceived things as sounding authentic, but sometimes less “easy listening.” I found that there was a different pleasure from the realness of the Red portrayal versus the pleasure of pleasant sound such as tube glow or accentuated punch. Naked can be off-putting, but also euphoric :-)

I’ve heard tubes change, but in general, I’m not confident I have the ear to discern burn in, or can attribute changing perception to a physical object, so the initial perception of the Black being “hard” is a cautionary tale for me.

Hi Gwalt,
Your experience with the SR Red fuses makes sense to me in that these outcomes are all individual in nature with the numerous variables. 
As you  note,  fuses are no different than  comparing cables or any audio products,  results will vary.  In your system another fuse may be an ideal fit.

The Red fuses have been stellar in my system and a wonderful discovery,  so I'm very curious to hear the Black version in my system. The Reds contribute to a full bodied tonality and very fleshed out harmonic overtones and are beautifully 3 dimensional. So for a multitude of factors results will be diverse among listeners. Good luck with your searce.
Charles, 

Oregonpapa:

I am glad the RED is working so well for you and did not mean to say it is not working for others....happy for you.

My comments are very real in my situation/system and why we have so many choices in audio. Fuses are just another point of integration along the process of making your musical enjoyment. Simpler put no one fuse is better than another in all situations. Trust your enjoyment and what works for you.

gwalt

^^^ The experience I've had with the RED fuses can be encapsulated in this:  There are NO speakers in the system. In fact ... there is NO system. The music and performers are completely detached from anything and just do their own thing in the room. And very musically so, I might add.

While the BLACK fuses have been an improvement in some areas, most notably transparency, a wider sound stage, and a lower noise floor, its like I'm listening to a stereo system and not a live event. After leaving the CD player on repeat overnight again, this is far less of an annoyance than it was the night before ... more evidence that the two fuses are still breaking in.

Its almost there ... but not quite. The CD player will be in the "repeat"  mode for another 24 hours. Stay tuned ...
I posted some time ago I was using my preamp. for evaluation of high end fuses. I am using a HIFI Tuning Supreme with over one full year of time on it for a starting evaluation. I now have over 125 hours on a RED fuse and must admit in my system it sounds thin and more HIFI than musical. I am going to put more time on it to see if anything changes to make sure it is not a burn in factor. Today I received my order of the AM beeswax fuse to compare. From what I have read it appealed to me to at least try from a music perspective. The point is as discussed along the way in this thread that these fuses are not a lot different from cable tests in that voicing and taste is very critical to one's final satisfaction. There has been a lot about the RED fuse here and so far I have not found its magic and if the BLACK turns out to be at an even higher point of the same then I am glad for all of the information. As in audio YMMV but do take your time and let your ears, mind, and soul do the talking.
One wonders if there’s any advantage to quantum tunneling say an entire transformer....hmmmmm. Or all of the internal wiring in a preamp. Maybe provide spools of quantum tunneled hook up wire.
This thread is actually more entertaining than I previously thought…ranging from near platitudinous mysticism, to squirm worthy oddly florid quasi-paternal statements of the obvious…I'm tellin' ya…this stuff should be mined for material supporting a sort of "b team" mass psychosis or early Harvard Lampoon level esoteric parody. I any case, a wonderful thing.
I most certainly believe in component/accessory break in periods. I have heard this first hand myself over the years,time and time again. In some instances,the break in period would even go in another direction other than the one I was hoping for,before coming back around to where I thought it could/should be.

But,without any reservation, I also believe that a lot of what we hear can be based on how our mind works in tandem within the bounds of mood,and/or,emotion at the time of any given listening session. This mind set may or may not be in synch with our aural expectations. There have been times that my system sounded so wonderful that I thought it could not possibly get any better... Then there were times when I just wanted to toss the whole system into the street,and start anew.

We humans are a fickle bunch for sure,but I guess the bottom line is...whatever works best for you, and your needs, in your system, is ultimately the correct way of going about your audio business. What one feels works...or not... in ones own system, is what matters most...Not something that someone else’s expectation is...according to their own likes, and and dislikes...aurally speaking,of course.
Jafreeman, i do agree with you. 

If it sounds good, it's good, maybe just a little smoother but not drastic, i have heard the chord cable users saying the cables sound real bad when new and new in excess of 500 hrs in which there is a transformational change. 

The basic characteristic sound show maybe with just a few hours running and at most by the next listening session.

If they sonic character is not immediately appearent, best to leave it to run with no further sessions until 2 to 3 days before reassesing.

I would think the Black cannot sound similar or as smooth as the Red, i associate more clarity with a less smooth or easy listening and more upfront sounding, some tracks actually may start showing more grain as well due to the more revealing character.

I definately found the Reds on the smooth side without any critical listening, itbwas there from the 1st go. I actually felt the SR20 sounds brasher and boulder but not as smooth and balanced sounding.

With all the reports of break in occurring with all new gear and parts, and especially with the more unexplainable improvements in sound, I believe there are neuronal pathway changes occurring in the primary audio cortex, wherein, along with the other senses, we finally experience and identify with the external environment. Cortical sensory processes are not as well understood as those in the sensory organs, i.e., the ears and eyes.  There must be new synapses forming as we listen to familiar music heard under different circumstances, such as with better acoustics or from a less-distorted playback system.  In my experience, I hear the music more clearly and completely when a new audio device is introduced.  You may say this is because the item is breaking in--settling in. Yes, I agree wholeheartedly--there are profound improvements as a piece settles in, but there must be something else going on at the interpretive end of things, because I, and others, I must assume, are hearing improvements in familiar music that become hardwired, much the same as memory does, only the newest improvement is built upon the last improvement I remember hearing, which is in itself superior to the ones before that. I believe that aural memory is quite accurate in listening to the same system that is undergoing small changes. I do not have a lot of faith in aural recall with A/B testing in an unfamiliar situation--this is not what I am referring to, and I dismiss naysayers who rely on A/B "shock" testing to disprove the efficacy of upscale fuses and cables, etc.  You who listen carefully to your own systems know what I mean here. in conclusion, I believe the more you listen to music you know, the better it sounds--even after something breaks in.  

Oregonpapa; " How can anything continue breaking in when the power is turned off?" 
I know memory can be a funny thing and I know this is true in my case. Having said that I am very sure this happened to me twice.
The RED changed in a significant manner while turned off for 20 hours at the forty hour break in point. This is when I knew there was no way that darn fuse was ever coming out of my amp.
The only other time a huge change took place to my gear while turned off was when I installed a Entreq Audio Silver Telus. Connected it to my amp played music for several hours then perhaps 20 hours later started up some music and.... WOW!
^^^  Charles ... "blooming wide open" is exactly what the RED fuse did in my system. Interestingly enough, it happened between listening sessions overnight with the system turned off.   I don't understand this phenomenon,  but it has happened on other occasions with equipment or tweaks that are in the break-in period. How can anything continue breaking in when the power is turned off? I've had this experience with cartridges, cables and electronics as well. Not every time ... just some of the time.  Maybe some of our electrical engineers reading this can explain it. Is it just me ... or do molecules continue to align themselves properly without an electrical signal passing through? I failed math in high school ... but had the best dance moves at the prom.  *lol*

Oh, and last night I played that Curtis Counce CD in your honor. There is an extensive drum solo on one  of the cuts that puts the drummer right there in the room. 

Cheers ...
Oregonpapa, 
Well the Black fuses are apparently moving in the right direction nice and steady. Time and patience is required for the performance progression. 
These fuses may be on the verge of blooming wide open. Thanks for the updates. 
Charles,
