Quantum Science Audio Thread

Keep them away from the chickens too!
ps
Thank you, Frank.

I discussed the fuse issue with a friend who is a manufacturer and audiophile and super knowledgeable.
He simply says that you hear a difference with the QSA fuses because they increase the voltage flow. Seems logical that a stock fuse creates a kind of bottleneck. The colored fuses open it up.
However, he also says to run away fast if someone tries to sell you a $2400 fuse.

"voltage conditioning process" ??????

Really! fuse can do this🤦‍♂️

I'm a little late to this party, but I can attest that adding 2 SR Orange fuses
(1 to my preamp, and 1 to my amp) literally left my jaw hanging open.

Really!  a fuse will do this🤦‍♂️


Wouldn't surprise me if Synergistic Research and Quantum Science Audio, are one in the same, now that SR has fallen from favor and Quantum is the new cheaper snake oil fuser on the block.

All that the members need to know that are thinking of buying into this fuse snake oil is

A fuse:
1: two end caps
2: short piece of fuse wire connecting the two end caps through a glass tube (that’s all she wrote).

I ask what can be done to that 10mm of fuse wire, by these companies that have no technical credibility at all

To those "non technical" members that are interested, do not listen to fusers, listen to the techs of this industry that design the audio products you have.
AND YOU WON"T SEE THEM ON THREADS LIKE THIS AGREEING WITH FUSERS ABOUT THE SOUND IMPROVMENT DETAILS AND AC FUSE PLACEMENT DIRECTION, EVER!!!

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, bend, stretch and get crusty with electrolysis formations on their fusible wire elements before they give out, as these pics show of a fuse wire element ageing over time show. https://ibb.co/9NbTwqK
(even the $$$ boutique ones will age just as much also)

Cheers to those "non fusers" George

Let us know how the QSA fuses sound.

That's a LOT of money for a fuse. A couple of hundred bucks I can rationalize.

I don't think I have the equipment to support a thousand dollar fuse upgrade.....

Synergistic Research puts out some good stuff. About the limit of my wallet, too.....but if you have the money, by all means report back with your experiences on the QSA stuff.

P.S. Is there any way to block or ignore users on here?
