Quads - Just a couple of questions

I have traded in my 18 month old ML Odysseys for the Quad ESL 2905. The Quads as expected lack the LFE of the MLs but in every other way, to my ears, are among the best speakers out there. You need a minimum of 50wpc and no more than 100wpc.IMHO Tubes is the way to go.

i need a big room for the new quad? i have 13 1/2 x 20 1/2 x 8. thanks.-

"would atma m60 have enought power for a 4 ohm load with less than 87 db? Would you need the zero-autoformer?"

I am against the autoformer which IMO is just a a fancy name for transformer and defeats the purpose of the OTL.

I think 60 wats is enough. The amp is doing so much right(class A, otl, triode, power supply)it gives you a real 60 watts.

Yes, the AtmaSphere M 60s have plenty of power and sound wonderful but you must have the autoformers to have them at their best with 4 ohm impedance speakers. I have the Quad ESL 57s and a it is a great match. I have also had the M60s hooked up to inefficient 4 0hm loads and they are great as long as you use the autoformers.

Actually, I'm thinking of pairing the Quads with an Audio Research Ref 110.
