I was about to pull the trigger yesterday on an Orange SR fuse. I bought my Innuos Zenith from Mike at Tweek Geek so I will call him today and get a couple blue ones for my Zenith and PrimaLuna EVO 400.
Quantum Science Audio light blue fuse; $71, what a bargain!
I wanted to start a new thread about the more affordable versions of these fuses. I don’t doubt that the higher end versions are amazing, but most of us aren’t very likely to be able to hear them for ourselves. Fortunately, pretty much anyone who is serious about building a musically enjoyable and engaging system can get a good taste of what they’re all about.
I’ve had the light blue QSA fuses ($71) in my CD transport and DAC for over two weeks, now. They replaced SR blue fuses, at around twice the price, and easily bettered them. I am expecting one more light blue tomorrow, to replace an SR orange in my amp. I’ll give an update on that, once I get it installed and listen.
Meanwhile, here are a couple quotes from my posts on the other thread:
“What I am hearing is; voices & instruments are more solid and lifelike, with increased natural detail and sense of space, better dynamics, and a more relaxed overall sound.”
“Just got in a second light blue fuse for my DAC. So far, more of the same improvements I got in my CD transport. Very nice!😃 One thing I appreciate is the break in seems to be pretty quick, without any of the nasties you get with some other stuff. Pop it in, and you’ll hear improvements in short order, at least that’s been my experience.”
I am continuing to greatly enjoy what these fuses bring to my system, and am really looking forward to getting the last one in my amp.

Just clean and tighten your fuse holder and re-new your fuse (if old) with a good quality 50cent Bussman, Littlefuse or similar, as with "many switch-on surges" they do deteriorate and get crusty as these pics show of a fuse ageing over time. https://ibb.co/9NbTwqK (even the $$$ boutique ones will age also) Cheers George |
Wrong, it’s the opposite, and shows lack of technical knowledge. As fuses get their worst punishment at "switch on" that’s why they blow sometimes for no other reason than age. It also shows the power supply is very large with good amount of "storage capacitance" to charge up, and that the amp could be very in class-A/B bias. And last the amp could be tube which needs even more current at startup, because of the added heater factor surge at start up of tubes, So proves that above statement totally wrong. As I said to those that are interested.

Love the way you just make things up. Shows a lack of maturity. Any decently designed piece of gear will account for current in rush during "switch on". There has been progress since the ’50s. Meanwhile, I’m continuing to enjoy listening to my gear with their HiFi Tuning Silver Star fuses, which have done journeyman service for the last 7 years. You've proved nothing wrong with my statements. That, and no one on this thread cares what you think. All the best, Nonoise |
