Replacement power. Ps

The Clayton’s are world class. I think the same league as the Lamm’s. I’m thinking perhaps a vintage Levinson recapped. Not sure of Lamm’s future with Vladimir’s passing. 
Thanks to all for their comments. 

I actually know what you mean about the trips to Brooklyn, one of my ML 1.1s kept switching into standby during play, turned out to be a defective relay but took a few trips as it was hard to find because it was temperature-related.  As for a replacement, in addition to the ones mentioned above, Ayre amps have always impressed me with their ability to convey the music like Lamms do, not class A operation but worth auditioning.  Same with VAC in tubed amps.

Audio Research Reference 160m monoblocks or 320m (I gather shipping in the next couple months).

You looking for an upgrade? Your musical preferences? 

I’ve always thought Clayton Audio amps were some of the better Class A solid state amps around and quite a value for the performance they offer.  Here are a couple reviews for their M200 mono blocks and S100 stereo amps FYI...

Would like another pair of mono class A amps.

It looks like the Lamms are 100 wpc amps. A good 60wpc (or more) tube amp/amps might be a way to move the sound in a better direction. However the Lamms are well respected so it might be hard to do better but tubes might take you in a new direction.

Not interested in a switching amp. 

Would like another pair of mono class A amps. 

These are M1.1 mono amps. I would love something that will work with some type of consistency. Too many trips to Brooklyn and they are broken again. Both blowing the main fuse. 

M 1.1s or ML 1.1s?  In either case, I would be hard-pressed to come up with something better.  What aspects of your current setup are you looking to improve?

Are you open to Class-D?
