Quantum Science Audio Thread

I found Frank's post about the Prototype and then SR Purple to be quite valuable, as it kept me from purchasing a QSA fuse, that I then might have had to sell at a loss.

millercarbon,

I believe you put the QSA stones on the output transformers of your amp? If so, did you leave them there? I’m considering getting another set of all three, and that’s where I’m thinking of putting them.

Yes, they are lined up L to R across the top of the transformer cover. Not the prettiest things it would be nice to find a better location but the sound the other night was so good, Sinatra-Basie always a good one but after putting some hours on the amp watching Free Guy and late at night OMG so incredibly good!

QSA fuses are a sure improvement. But I question the stones. At least only one pair of red on my power conditioner, preamp power supply, and amp transformers. At least on my system... nothing.

Can't argue with that. I found red to be the least impact, with only a very small improvement in making the sound a little smoother or more liquid and very slightly deeper. Maybe good for someone with a lot of SS or digital or anything wanting a bit less glare or grain. 

Blue was more obvious, and Clear most of all. Any one alone could be used to fine tune a system without changing anything too much. All together, which is how I'm using them, I found the combination to be fairly well balanced.
