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.

Ozzy, industrial distributors Digikey, Mouser, and Newark Electronics can supply pretty much any non-audiophile fuse you may require.  Digikey has no minimum order requirement or handling charge.  Not sure about the others.

atmasphere,

Thank you for the help. I should have my NOS tubes from Russia soon, they are now in the USA. And I already have my NOS RCA’s. So soon I will be able to do the dreaded 72 hour burn in without music.

almarg,

I did buy a few fuses locally. And I ordered about 25 more on Amazon. Glad I didn’t buy the exotic version $$$ SR Black fuses.

Thank GOD it's not an ARC and boutique fuses.   Otherwise early Christmas for the trolls.
