Amplifier for Quads

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.

I just don`t see the advantage in sonic/musical terms in a high power/high current solid state amp. It seems based on the dsign of these particular speakers a moderate power tube amplifier of good quality would yield better results.

I agree with Charles1dad; Roger Modjesky designed his RM-10 specifically for his own Quad ESL-57s.

I 've owned both the Bedini 25/25 and currently the Atmasphere S30 though I have not heard either with Quad 57. I can say that the Bedini 25/25 is highly regarded by Quad 57 owners as I was deluged with offers when I sold it.
That being said, I would second the recommendation for an Atmasphere OTL. Would recommend the M60 but you could use the S30 if the stacked Quads were wired in series (increasing the overall impedance).

Agree completely with Charles1dad. In fact, I have been told by more than one Quad 57 owner (I never owned them) that the Quads actually seem to be able to play louder with smaller amps like the Bedini, but particularly with quality tube amps, instead of big powerful ss amps. Go figure.
