I am so impressed with the positive changes brought about by swapping out a standard fuse for a Synergistic Research fuse in my tube linestage, I bought 4 more to replace the ones on the board in my Stratos Stereo amp. The fuses went in tonight, but no time to listen. Review in a couple of days.

Thought I'd share some pics of the proceedings. Check out the filter caps and stacked trannys. These are the parts that Klaus' uses in his totl pieces cause he felt so bad that he couldn't resolve my issues with running this amp in Dual Mono configuration with my SDA's:

    Lookin' good Fred! What is the blue cable connecting the smaller caps to the RCA outs? It looks familiar, but can't place what it is?

    Looking forward to the review of the amp with Synergistic fuses added.

    My response is: If you need 60 seconds to respond in one sentence, you probably should't be evaluating Polk speakers.....

    I'm looking forared to your review as well.

    FYI, you should keep an eye on that clear jacketed copper cable for oxidation.

    Good point, Jesse. It depends on what Klauss used though. I have an Audioquest something or other that I have had for years on end [clear, just like that one] and I have yet to see any oxidation. It's the only one I still have that didn't degrade in the box of goodies out in the garage.

    That wire has been used in Odyssey amps the last 10 years, no oxidation I have ever seen and I have owned my fair share of Odyssey product!

    Now fuses and Odyssey amps on the other hand, I have a bag of 50 fuses compatible with Odyssey amps! I hope the tweak works well! :)

    I believe it's Odyssey's Groenborg cable. Not sure of the construction, but they think highly of it.

    Funny thing, as much as I've read others talk about stranded clear jacketed cable turning green, especially Monster, I've not experienced it. I have some 20 year old Monster out in the garage for the last 10 years that still looks pristine.

    Will keep an eye on the stuff in the amp though.

    SR Fuse Review

    A little background: about a month and a half ago I decided to try one of their fuses in my Odyssey Candela linestage. This after reading all the reviews I could find on the various “designer” fuses such as Isoclean, Furutech, Hi Fi Tuning, etc. I kept looking for comparison/ shootout reviews by those who had tried the top fuses in each manufacturer’s line. I only came across one such review by a guy on Audio Asylum. So, based on that I purchased the appropriate value and installed it in my linestage.

    The results have been so positive I decided to splurge and get 4 more to replace those in my Stratos Stereo. I was a little hesitant about this as I had read some reviews that stated the biggest improvement with these occurred after putting the SR fuse in pre’s, less so in power amps. Also . . . . . . they’re f-u-s-e-s! @ $60 each!

    But life is short and I finally talked myself into it. The amp stays powered on 24/7, so the fuses had 24 hours of low current running through them before I started the music on night one.

    The albums played include “Silver Lining” (Bonnie Raitt), Susan Tedeschi’s Greatest Hits, and Chicago Transit Authority (their first album).

    Bonnie was up first and what I heard I wasn’t quite prepared to believe at first. We have an open floor plan with the kitchen open to the LR where the rig is. I hit play on the cdp and went to the kitchen to get a beer. As I was standing there, I noticed the overall sound was smoother, with vocals that were fuller and richer, more realistic. Not by a lot, but it was there. Individual voices in background harmonies were more distinct and the harmonies were not louder, but easier to hear and just a little sweeter. There also seemed to be a bit more overall slam to the presentation.

    One of the most surprising improvements was the change in soundstage. The SDA effect in my room has usually been tilted towards the right with some instruments well outside that speaker. This side is around 4-5 feet from the side wall. The left side has a large open area beyond the speaker, which I’ve always assumed contributed to a slightly diminished SDA effect on that side. It increased by at least 3 feet on the left side, with instruments often seeming to wrap around the listening position, almost behind it. Now the SDA effect sounds equally balanced.

    The soundstage is also deeper front to back. It projects forward about the same, but now has more depth.

    The bass doesn’t go deeper, but has slightly better transient response. Highs, also have a little better transient response, and there’s a little more air around instruments. It’s easier to hear background effects, such as tambourines, bells, small percussion instruments. My wife even commented on this and agreed with my description of the vocals.

    On the Susan Tedeschi CD the improvement was similar to what I heard with Bonnie. I’ve noticed in the past that on some of the songs (which were taken from different albums) when the hi hat is being played closed, it has a bit of a soft, hissy sound. More of the metallic cymbal sounds appeared last night, which sounds more realistic.

    “Chicago Transit Authority” was recorded in 1969, but it still sounds pretty good today. Peter Cetera’s bass just sounded great. It was distinct before the SRF’s, but it now has a liquid quality to the tone, yet not soft, with good attack and decay of notes. The trombones have more bite to the beginning of the note.

    Overall, I'd say that instruments and vocals have a more natural tone, a little more power and more air around each. The effect is more slam to the music and yet a more relaxed feel as well. Complex passages are rendered with a little more clarity. These differences were very easy to hear.

    The above is based on ~ 2 hours listening. I'll post if I hear other changes.

    The verdict: I would equate the improvement in sound quality these fuses brought to replacing really good IC’s with great ones, and perhaps upgrading a power cord or two as well. I bought these from www.thecableco.com, after trading emails with Synergistic Research. They were recommended as a company who would honor SR’s 30 day return policy.

    Bottom line: If you’re thinking of trying high end fuses give these a go. There’s no risk if you’re not satisfied other than the cost of shipping.

    Update: Damn these things are good! Nothing new to add, really, other than they're staying. Amp manufacturers should seriously think about cutting a deal with SR to include these when they build their product. They make a very good amp sound better - wonder what they'd do to a upper echelon one?

    Somebody (Darqueknight, F1nut, Blue Fox) give it a go :cool:

    This is on my todo list. After hearing what a PC can do, I have no problem believing that replacing a cheap, run of the mill fuse with a higher quality fuse can make an improvement. Along this line, I asked the founder of Shunyata if they had done any measurements on fuses, and he said no, but I should try it and let him know the result. I just am not that enthusiastic about taking things apart, prying out the fuse to find the size, and then hope it works when I put it back together.

    Also, I have been very satisfied with buying from The Cable Company.

    Which one did you audition in your rig, if you recall? Also, upstairs or down in the coffin area?

    Blue, downstairs. I'm not one to doubt improvements are possible when it comes feeding power to gear, but the fuse thing is BS.

    So a good friend and elecrtronics expert once told me that power supply is totally separate from the input / output signal supply chain and one and the other are not interrelated. So you all who think different had better beware! Personnally I have tested different power supplies and power source cords and have not noticed any difference. Which means nothing by the way as everyone will observe differing effects with differning equipment.

    Well.......it all starts with the power supply. The better it is, the better the end result.

    I have not tried the Synergistic Research fuses, but have all my equipment retrofitted with (mostly) Hi Fi Tuning Gold and Supreme fuses. I noticed a difference in clarity, detail, and seperation (soundstage) after installing. Definitely not a stark difference, but noticable.

    As stated, I have not heard the Synergistic Research fuses, however. I do believe fuses can make a difference, but a power cable will certainly make a bigger difference, in my opinion.

  • Might not make a difference in certain applications so while I don't argue that it makes a difference or not for any one individual as that is their opinion (nothing more nothing less) I just speak for the very noticeable improvement it made in my situation. It isn't open for debate as back n forth I had to change out to make sure I wasn't dreaming and no dreaming here . Just heard such a more refined sound with crisp detail and such a kick in the but change it was hard to keep the smile off my face. Keep in mind I am not doing this on an entry level network player but one of the best stand alone players on the market. It was amazing with the supplied fuse.. It just rose to a new level with the top of the line fuse I changed in the unit. And yes having a dedicated 20 amp line with all great cables and conditioners in the mix would be wise before messing with high end fuses.

    Happy Listening as it really is All About The Music!

    A few years back, I changed out the fuses in a big Kenwood Integrated I had with some Acme Audio Labs silver cryoed fuses. They were very reasonably priced, but they definitely made an improvement. That said, the original fuses were nothing to write home about and had years of use on them.

    I tried the blue fuse in my McCormack DNA-1. Started with the mains fuse and once swapped, I listened to "Don't Give Up" by Peter Gabriel and Kate Bush. Kate's vocals were immediately cleaner and I figured it was placebo.

    I changed back to the stock fuse and the upper registry of her vocals weren't as clean. I re-installed the blue fuse again and the vocals were noticeably cleaner. I did this about 3 times and each time was the same result.

    I can't say I heard anything different with the preamp but made a difference in the amp.
