Recommended amp for Quad 57.

The Berning amp you are referring to is the EA-230. Stereophile recommended it (almost 20 years ago) as an excellent match for the 57. While I've owned both the EA-230 and the Quad 57, I didn't own them at the same time, so I haven't heard them together. Based on their sonic qualities, it should be an excellent match.

Frank.

The Quad 405 amp, which is 100 watts per channel, has places on the circuit board to plug in 2 resistors (1600 or 1800 ohms if I recall correctly) to limit the power. With these resistors in place, the amp is perfectly safe with the 57s and sounds surprizingly good. I used this combo for several years until I switched to a highly modified Dyna Stereo 70. Another great amp (if you can find one) is the Bedini 25/25.

Oooh the 47Labs gaincard is amazing with this speaker.

Chel: While your here, what do you think about the Audiomat 30 watt integrated with 57's? This is an amp that first came to mind, but I have never listened to the line.

I don't know about that one. I've heard the audiomat with several small floorstanders but not with Quads.
