Thank you Eric, nice to see an Audiogon watering hole for fans of good class D amplification. Over the years, I have had a variety of very fine amps.... Among class D designs I enjoyed for several years the Rowland 312 stereo based on ICEpower ASP1000, and the Bel Canto REF1000 MK.2 -- also based on ASP1000. I agree with Ghosthouse that Merrill makes wonderful amps based on NCore NC1200 and NC500... Worth not only listening, but also owning. Read my super-favorable review of Merrill's Veritas monos at on Positive Feedback No.68:

My reference amplifier is the Rowland M925 mono, also based on NCore NC1200 modules, amongst its many component parts... It is an absolutely enchanting amp, which I have discussed elsewhere on this forum:

Yep, 4 years have elapsed since M925 has arrived at my doorsteps, and I am still in love with it.
Here is where you can find information on M925 design and architecture:
