Stereo use? Yamaha, Parasound Zpre3 and A21
HT, Marantz, Yamaha, Denon.
I sure fixed enough of the CS series. Surrounds and blown tweeters..
The tweeters, oscillating amps every time..
CS 3XXXs were all good performers and EASY to fix or work on..
If you knew anything about me, you'd know, I take things apart and change them if I don't like it.. LOL
About 4 or 5 pairs I REALLY tinkered with..
2 pairs of 3006s, One pair upside down, stacked and the tweeter disconnected on one. If the ceiling was 9 foot or higher the bottom box tweeter was disconnected. 8 foot ceilings, the top 3006 tweeter was disconnected..
A buddy still uses that set up in his shop.. Serious sound.
He's driving his stuff with class d. MP500s, and Mcintosh C20 tube preamp.. When I say drive I mean drive.. 115+ db.. I think its a 3 ohm load.
