Amplifier for Quads

The thing about power is you can only have too little. You can't have too much. Power is the best way to protect your speakers.

Of course he doesn't need the power. A TNT120 would suffice. It's just that the Acoustats were designed to adequately drive elecrtostats. Once Roy is done with them, they are SOA. A TNT 120 could be had for under $500. Roy would rebuild it for $400 which includes return shipping within the lower 48. Now you have a world class amp for about a grand.

An Acoustat TNT 200 will spank the Bedini. I've owned several Bedinis and like them. Still have a couple. But the Acoustats are more than a notch above. Extremely fast with extreme extension. They are simply stunning. Guaranteed to blow you away! Mind you the ones I have are rebuilt by Roy Esposito in Florida. He was one of the design engineers at Acoustat. He rebuilt 3 TNT200s for me and added balanced inputs and mono switch. They are 200wpch. in stereo, but in mono they produce over 1100 watts.

The 25/25 is considered the best match for the 57s by a lot of people. Why, I don't know. There are a lot better amps than the Bedini, even vintage.I can't speak to the voltage preference thing, but not only is he using a high current amp but he's using two that are bridged! Take a wild guess what kind of current is running through those 1megs now. I suppose the key to survival is to throttle your desire for SPLs.

Fair enough. I'm just so impressed with Roy's work, I thought I'd share my experience.
