Amplifier for Quads


Hi fellow Audiogoners - I am currently using a pair of bridged Bedini 25/25 1mg amps to drive my stacked Quad 57's. I welcome your timely amplifier recommendations for maximizing the sound of these classic and timeless speakers.

Hi Rmarcus - I've been going low budget with my ESL57's. I have a Bedini, and like it alot, but I like even more the VTL Tiny Triode. Other ones I considered were a Musical Reference EL84 amp (I like EL84's), Rogue (I forget the model). I also tried AtmaSphere M60's, which sounded good, I wasn't looking to invest that much in the system.
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.
Sorry, but it makes no sense to drive ESL57s with 200W, much less 1kW. Either the recommended VTL Tiny Triode (used market, no longer made), the inexpensive Quicksilver Mini-Mite or the Music Reference RM-10 Mk II for a bit more money would be more than enough and will bring the best in your classic ESLs.
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.
