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.

Holy Cow!- Considering that your speakers are far more efficient than my Vandy Treo's, you have me thinking about adding a pair. I recall Steve McCormack saying that the Zero's do make a difference, even with Solid State.

Driving easier speaker loads (high impedance) should be beneficial for all types of amplifiers and not limited to just tube power amplifiers.

atmasphere,

I just posted some pictures under "ozzy system" page.

gdnrbob,

I was wondering why there are not any used Zero's for sale. They are a real plus.

charles1dad,

The amps seem like they are now more powerful.

Ozzy,
I understand , my speakers are 14 ohms and it seems as though my amplifier is just coasting along very relaxed and natural.

+1  It continues to amaze me how many people don't get this basic fact!
