Are WA-Quantum Chips even sold anymore?

Cable Co. among others sells the WA chips. The rumpus sure has died down, though, you're right. My theory is it's pretty easy to saturate the market since there are only so many audiophiles. ;-)

I think sometimes they helped a lot. In particular I liked them on fuses. On speakers I found them to vary greatly, including harming the sound on some.

I have a bunch. Semiconductor chips, cable chips, inductor/coil chips, small and large capacitor chips. Fuse chip. What have you.

Geoffkait, I finally checked and have only two types-those for speakers and for cablees. I thought that I would experiment with the cables ones this weekend. I know the speaker ones harm the sound of the BMC Arcadias. I need to get some for the fuses.

Speaking of tweaks, I had a friend with a door behind her speakers. I gave her on Acoustic Revive QR-8 to put in the middle of the door. It did wonders and she wanted more. Acoustic Revive doesn't even have them in their product line anymore? I guess tweaks come and go. I must say that the HFC cables have caused me to remove many of my tweaks.
