I have the same amps. The UCD 400 HXR with the UCD HG (non switching) power supplies.
Running them off an SP10 preamp into Analysis Omegas.
They are incredibly powerful, dynamic and resolving. In some respects, they’re the best amps I’ve listened too. But, I get an occasional sense of glare at the upper frequency extreme. It can be edgy and a little annoying at times. Are you feeling that too? I’m not sure, it’s recording dependent perhaps.
i will be comparing to a pair of VTL MB 450s soon which will be a nice comparison.
