The new Synergistic Research BLUE fuses ....
teo_audio I think also breakers would not deteriorate as much over time with switch-on surges like fuses do.

The ’blowtorch’ thread over at DIY audio was and is full of audio designers. Fuses and circuit breakers were and are topics of discussion. Circuit breakers are preferred due to their ’least’ level of sonic interference. Fuses end up being the item of choice due to the manufacturers, not the designers. Fuses and fuse holders are much less expensive than circuit breakers. Since one has never heard the amplifier they own with circuit breakers instead of fuses..the question remains...but as a question that is non existent, unrealized, unasked. Thus the manufacturer saves the money or costs of 4/5/etc circuit breakers of optimum quality, per standard amplifier, as they only have to buy and install fuses and fuse holders. Fuses...which don’t have failure modes like circuit breakers might....and any circuit breaker problems (ie, unknowns, and we don't want unknowns) stay off the manufacturer's plate of after sale issues. |
Most "experts" in audio engineering I know don't give a hoot about silly magical tweaks with no basis in reality, and if you can find one who does, well, so what. All are welcome in Wonderland…I remain a believer in Littelfuse stuff because since I'm a wealthy man (!), I can afford the 2 bucks. I can say there's a lot of evidence that breakers "sound" better than fuses, but there isn't, so I won't. |
Again, I will post that the most conservative, non-tweaking audio engineer/equipment manufacturer who heard the difference between "new" Littlefuses and my SR Blue fuses, immediately went home and installed circuit breakers where his fuses were located at (we have the same amps). He has no tweaks in his audio system which sounds superb. He hates any liquid treatment on contacts including TC although he will never try it. I thought the circuit breakers made a tremendous difference from the Littlefuses he previously had installed. So, if the difference between fuse quality and circuit breakers were not so obvious, an expert in audio engineering would not have changed his equipment. But he heard it and he did it. |
George, please just TRY a Blue fuse for once instead of just decrying them all the time. All you guys have heard is this, nothing more nothing less. A fuse is like a light globe too many switch-on’s and it will bend, harden, and carbon up the filament, and then one day it will blow, always on turn on. Ever noticed how much brighter the new light globe is compared to the same old one before it blew even though they were the same wattage?? That should tell you fusers something!!

tel55511 posts03-14-2018 11:08amGeorge, you'll hate this, but I'm going to say it anyway. If you don't know the difference between your and you're, then in my book your opinion doesn't count at this level of debate. Really!!, just for interest you got just 11 posts and nearly all are on fuses, your opinion and motive is in question not mine sunshine . Cheers George |
I have been very happy with the black fuses, with a new amp it is going to be high time to try out a blue fuse in it. expecting good things only from prior black fuse experience. George, please just TRY a Blue fuse for once instead of just decrying them all the time. By your own admittance many posts ago you have never actually tried one, unless this has now changed and you are basing your arguements of actual listening experience? I have found in my audio journey throughout the years that there are PLENTY of things that defy any scientific explanation! |
George, you'll hate this, but I'm going to say it anyway. If you don't know the difference between your and you're, then in my book your opinion doesn't count at this level of debate. That's an opinion based on years' worth of online observation. Yeah that's harsh, I'm sure there will be the professionally offended along soon enough to shoot me down this way, that way or another way, but in that succinct misspelling, you told me everything I ever needed to know. You'll never get this stuff, mark my words. Genuinely no offense intended. I love my blue fuses. In the UK, they've temporarily sold out. We're all wrong, George. You're (sp) correct. :) |

So your saying it was an accidental that the two channels weren’t recorded at the same levels, and nothing else was different? fair enough. As you said " I do not go here often " as your minimal amount of postings show. Can I suggest then if your going to go to this sort of trouble of changing fuses, then recording, and making video’s to do an A/B to get the "gullible" to be swayed one way or another that you do so using proper test equipment to get things spot on. So then there’s no suggestion that the video is a fraudulent A/B and that then be only misconstrued as maybe shilling for SR. Cheers George |
@georgehifi I do not go here often, so I did not know there were other posts. I also do not have measuring equipment. I just turn the volume knob to the level I usually listen. Beside changing fuses, no other difference in my system. Both fuses are relatively new and have the same value. One is Bussmann, and the other Blue. Thanks |
roberjerman"To paraphrase the estimable Gertrude Stein: A fuse is a fuse is a fuse ..." It is clear from the assertion presented here in the absence of any facts or supporting material that you are what some have called here in this forum a "measurementalist" so please provide information about the double blinded testing that you have undertaken to arrive at this steadfast conclusion. Do not forget to include all the details on the test so that it can be independently verified by your fellow "measurementalists." |

Accident or not, it’s taken even more credibility away from the notion that >$100 boutique fuses have a major impact on sound, unless it was a crusty old $2 fuse that was taken out that had seen "too many switch-on surges" and was due for replacement with the same "new" anyway.

The normalization process is done by YouTube, not the user. YouTube reveals EXACT volume normalization values - find out how to see them - Production Advice It can take quite awhile for it to correctly set itself. It's not on the guy who went to the trouble to download it and to assume he tweaked it or is not to be trusted is pretty lame. Even with that astounding .2 db difference, it's pretty easy to "hear" the differences if you know what to listen for. All the best, Nonoise |
George---the guy was impressed with the SR Blue fuse, and he went to the trouble of posting an A/B, which is more than anyone else has ever done that I can recall. And---did YOU hear the difference? That should be your first comment, but you decided to discredit the poster by casting doubt. Yeah, I'm sure there was no "accidental" misrepresentation--any reasonably forgiving person could see this, but not you--no. |
do not attempt to discredit the poster with accusations of fraud No one attempted to discredit him, but the question was asked "why the differences in playback level" favouring the SR Blue fuse setup? and was anything else "accidentally" done? as this was not his intent.And you know this for a fact? Cheers George |
chumsusi Look at both the video stats, first I’d like to know why there was a difference in playback volume 63% v 64% (3.8db v 4db)???? And what other difference are there??? before someone records both and analysing them with the right equipment. Cheers George |
Here is my system with and without Blue fuse. With: https://www.youtube.com/watch?v=TcPQOz0_xZY Without: https://www.youtube.com/watch?v=i0LtGGgHvMo The Blue had had less than 20 hours Happy listening! |
I want to chime in that SR HFTs and Atmospheres require fine tuning to work in some rooms. My room thoroughly dislikes the Atmosphere anywhere between my speakers/in front of the listening area. It congeals the center stage into a slim line, removes the air and depth of a recording. I moved it to the back of the room and it works fine there while restoring the great sound I had previously but a little closed in still.. Next, I then wanted more height/openess in the sound so I experimented placing the HFT on the central front wall up higher, an inch at a time. I ended up 8 inches higher, at the top of my speaker basically. That also thinned out the bass/lower mids. I then lowered the four speaker side panel HFTs exactly one ince which is recommended to increase warmth and bass. Voila! That was one I was looking for, a perfect balance. I tested out everything from electronic rock (Yello) to classical chamber music, solo instruments, mono recordings, to 50’s jazz to opera to bid band with vocalists. Everything sounded tonally rich, open, widespread as the recording would permit. I like to just set things up and not futz with them (most of my equipment is 12 years old or older). In this case, SR requires you to adjust room treatments. Total Contact together with SR Black Box is a great match. My wife heard the combo and said it brings the music to life, similar to the $1.5 million Von Schweikert/VAC/Kronos system featured at every show that she would like to have (I can’t afford it and it’s too big even for my garage size room). P.S. I don’t take sides in the which is better, CDs or LPs debate. They both can sound great or mediocre, depending on the recording and mastering. I do have audiophile quality equipment for both, but it is certainly easier to listen to and store a CD, with boxed sets selling dirt cheap on Amazon. I have 78s and LPs which have zero chance of ever being reissued in any format so I’m not giving up those ever. |
Just changed from SR Blacks to Blues at the AC inputs in my ARC 210 (250) mono blocks, and the improvements in inner detail, transparency/decay, overall clarity and presence are profoundly better than the very good Blacks. This is on first listen---the same as I have heard with the other Blue additions in speakers and CDP, and I must compare these to a component upgrade. I can only suspect that components are woefully underserved regarding quiet current through stock fuses and that noisy current is an artifact of those fuses that degrades the modulated signal. I am, again, very happy with the SR Blues, even right away. |
david_ten ... Your best bet would be to order the Blue fuses and take advantage of SR's 30 day return policy. If you don't like the results you'd only be out the return postage. BUT ... I'll bet you won't be returning them. :-) https://highend-electronics.com/products/synergistic-research-blue-quantum-fuses Frank |
simguy ... Thank you for the kind words. Glad you're enjoying the Blue fuses. Who knew! Anytime I can get a major upgrade in SQ without upgrading the electronics, I'm in for it. Also, the TC is a wise move. Even better than the Blue fuses IMO. I still cannot believe the improvements afforded by these two items. Oh, and Herbie's tube dampeners shouldn't be overlooked either. There seems to be no limit to what the good tweaks can do for a highly resolving system. SR's HFT's are no slouches either. Man, that was a major improvement in terms of a room treatment. Still don't know how they work, only that they do. :-) Frank |
simguy: I am glad you are enjoying the Synergistic Research Blue fuse. My horn system normally is powered by the Art Audio PX-25 amp that puts out 6 watts a channel. I decided to try a solid state amp and picked a Pass Labs INT 60 from Mark at Reno Hi Fi. Putting a Blue fuse in this Pass Lab amp is a major upgrade . The amp is now much more musical sounding. Pass Lab amps and SR Blue fuses are a wonderful combination. David Pritchard |
Hi Frank, I rejoined audiogon to thank you for posting on the blue fuses. My former account I closed a couple of years ago. I had a black fuse in my amp for about a year and a half and just bought blacks for the rest of my system about 3 and a 1/2 months before the blues came out. After reading your positive comments and others on the blue fuses I decided to try one in my amp to see for myself. From the get go it smoked the burnt in black fuse. I didn’t have any intentions of replacing the recently purchased black fuses but once I heard the one blue fuse I decided to replace everything including the ones in my Foundation research power cord conditioners going to my Martin logans that just had Isoclean fuses I bought years ago. I laughed at your comment ( once heard the checkbooks will open ) You were right. I had an audio friend come over to hear the difference adding blue fuses one at a time adding fuses into the system besides the one already in my amp. We did the pre amp first and re listened, then the phono stage and then both power cord condiioners going to the logans. The change was in sound was astounding and money well spent. Thanks again for starting this thread. Unlike a lot of nay sayers around here, I actually try a product first hand before forming an opinion. I will try the tc also once I get a couple more final cords I want . |
No, the SR Blue only got better but remained superior to the Black after 3 days as well. Could be something else in your room. I'll tell you that I often had bad sound days (not nights) for no reason. I recently purchased the SR Atmosphere XL4 which negates all types of negative electrical waves in the room and stimulates the SR HFTs I also recently installed. During the last week of use at all times of the day, no more bad sounding days. I'll see if that holds true when the A/C is running in the summer but I suspect I've found a cure for inconsistent sound days. |
As many are aware of an break in period required of equipmentand cables and most recently on my part SR fuses which up until the Blue's have exhibited a steady upwards progressive improvment esp the Black's. Three days of audio bliss into a new Black and after my usual system warm up time I experienced a session of notably decreased dynamics and soundstage over my previous three sessions with the new fuse, most curious as nothing had been altered in my system , all biases checked as normal, connections etc.etc. I am wondering whether any other adopter of the new Blue's has experienced anything similar ? |
