You will want an amp that produces at least 120W/channel. I use and love Atma-sphere amps, but many knowledgable folks also like the Wolcott amps. You cannot go wrong either way, apparently. If you choose Atma-sphere, you will need at least a pair of MA1s. (The M60s probably are not sufficient in power.) And you should also modify the hi-pass filter in your spkrs with the Sound Lab factory "kit", which increases the effective impedance of the spkr at midrange frequencies, making it an easier load for an OTL. The kit is available for ca $75, if you are a DIYer. Otherwise, the factory will make the modifications for you, if you send them your power supply backplates.
