BAT VK-60se vs Atma-Sphere M60 mkIII

6.5 ohm minimum impedance with 8 ohms nominal also happens to be the Merlin VSMs specs - again, match OTLs with the right speakers and I think you will have a very good result.

If you email Ralph he'll recommend some manufacturers that work well. I know Audiokinesis will be on his list and Duke is a super great guy.

You might also consider Coincident for the M-60's.

As for the MA-1's...I have a pair of Mk III's and absolutely love them. Mine are currently mated with Vandersteen 5A's and it is the best I have heard the 5A's sound. This combo produces all the details and texture that the music has to offer while enveloping you in the music.

I did try the Zero's with the MA-1's in a different setup (Emerald Physics CS2's). While it tightened up the bass, it did indeed cast a haze over the sound that I ultimately couldn't live with.

Go for the Atma-Shere M60's. No brainer....
