Amps Atma-Sphere M-60 Mono blocks OTL design

I just purchased a used OTL Atma-Sphere M-60 mono blocks that I have sent to Atma-Sphere to be upgraded to the current model 3.3 and I also added the option of a higher quality power supply and V caps.

I have sold my old trusted Eggleston Andra 2’s speakers and have built some monitors using Aurum Cantus ribbons (102db) and Aurum Cantus midwoofers (90db) that are both rated as 8 ohm nominal. I have a DEQX Premate and will be crossing over to (2) JL Audio F-113 subs at 80hz.

Currently I am using a solid state high power stereo amp (Pass Labs) that I used with the Andra 2’s.

The Atma-Sphere M-60 is rated at 60 watts class A and is said to work better with higher impedance loads.

It will probably be a few weeks until I get the M-60 and was hoping someone could provide opinions of what to expect.

I listen to late 60 early 70’s classic rock music mostly. Sometimes loud.

I got an MP-3 with my MA-1's and am so glad I did.

gdnrbob,

Sounds like you have some pretty good system synergy.
Do you also use a sub?

Yes, I have the Vandy 2w's, but just bought a pair of 2wq's.
I probably didn't have to, but it was in the back of my mind, so heck, I did it.
I was looking at a pair of Quatro's here on Agon, but decided to keep the Treo's as I:
1. Love the way they look and sound.
2. Can't get the energy to move another pair of speakers.
