Amplifier for Quads

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.

My choice would be Atma-Sphere.

The TNT amps were designed to mate with Acoustat's own line of big panel speakers which required much more power than any of the early Quads. I'd be afraid of frying the panels with that much power.

I'm with Syntax, Atma-Sphere would be a much better match and would be a huge step up from the Bedini.

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.

Agree with Csontos. Anyhow, any restored Quad should have a clamping circuit, which will protect your speakers.
