Amp for Quad ESL 57

I wonder whether the new Quad II-Forty might a better choice. Any idea?

I don't particularly like most of the new Macs... BUT my idea is, it is most unlikely. Keep the Mac. The Mac's weak point is the phono, then the pre section (BUT, you do get tone controls and a mono switch -- both work quite well). The power amp section is good, with OPT which seem to favour linearity from mid-bass up to reasonably high. The Quad is... well, "pleasant". You;re fine as is.

the quads do not need power. find a low wattage amp, under 25 watts that you like.

Find a Berning EA-230.

I've tried a number of different amplifiers and find that vintage English tubes is what they prefer. I'm currently using a Radford STA-15 that sounds wonderful.

Leak Stereo 20 works as well but you will need to pot down the input.
