Hypex NCore 1200

Guido, That is great and thanks for the info.

I think the reason the room sounded just OK (again not a bad thing) when I heard it at the NY Audio Show this year was that they kept on switching the two different amps in and out. In my opinion a dumb thing to do sound wise. Even many Class A and A/B amps need time to "settle" to sound their best.

I've had HRS Nimbus/ Spacer under the amps with both top and bottom Nimbus.
I was in shock after removing the top Nimbus so the spacer contacts the bottom of the amp while the Nimbus isolate the Spacer and the hardwood amp platform. The sound is so so much better than my MC501 amps now. Really don't understand how these changes made a huge difference!
It seems 2 Nimbus caused too much damping. This has made the sound more heavy!

I should have said the coupler and spacer

Finally heard the Ncore-based Mola-Mola Kaluga monos at RMAF. My early impressions are at:
