What speakers match well with Atma Sphere?


I'm considering the switch to Atma Sphere M60's tube mono blocks. As much as I love my Pass Lab X600's, as a renter who has had to move three times in two years, they are a pain to move. However, my current speakers are Dynaudio Contour 3.3 (4 ohms) which require a lot of power. My understanding of the Atma Sphere M60's are they perform well with 8 to 16 ohms speakers. So what would be an excellent speaker in the $3000 -$4000 (used) range?

Coincident Partial Eclipse or Victory (if used) would fall nicely into your price range. They are fairly sensitive and have very OTL friendly impedances. I believe Tonian Labs also makes some high impedance models, but I am not very familiar with that marque. With the right sepaker, I think you'll be surprised how much amp the M-60 gives you for a reasonable price.
Merlins have always sounded great with Atma-Sphere. I also used Sonus Faber Electa Amators to good effect.
I second Sdatch's recommendation of the Partial Eclipse. I prefer the Coincident's Eclipse line to the Victory line but it is a matter of taste. If you are patient, you may be able to get a Super Eclipse within your price range. This is a great speaker with the M-60.
I second the Merlins. I have owned very many speakers over the years (ie: Quads, Logans, ProAc, big Apogees, Verity Parsifal Encores, etc.) and the Merlins are simply amazing, given you do not do hard rock at ear splitting levels. They do not go super deep, but their bass is incredibly tuneful and articulate with world class resolution and soundstaging. They breath life into the music and should be a super match with the amps.
