Replacement power. Ps

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

You looking for an upgrade? Your musical preferences? 

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.

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.
