Speakers for Atma Sphere M60 mk3

@fredag For the M-60s I would use speakers that are at least 8 Ohms and 91 or higher efficiency.

With any amplifier, tube or solid state, its beneficial for the speaker to be easier to driver rather than harder; this will always result in less distortion! The higher impedance speakers will also be less critical of the speaker cables.

I would expect the class D to work fine with the Elipsas, depending on the size of your room and how lively it is.

@atmasphere Room is 26 x 14 ft ceiling is about 9 and I like the music in some how realistic volume level. I listen a lot to live music also , jazz and classical, so the "live" feeling at home is important to me. The Elipsas can play quite loud. The impedance curve drops down to around 2 ohms in the lower register so they are not easy to handle.

@fredag How much power are you running right now?

@atmasphere Mark Levinson 532, balanced/differential amp 400W@8ohm and 800@4ohm, etc.... I have a 12dB Rothwell attenuator between pre and power amp so I´m not using the full output of the ML.

@fredag Your room is a bit on the larger side. If I were you I'd be wanting to see if an audition could be arranged.
