I’ve been using a DIY Hypex NC500-based two channel amp for the past two years in one of my systems, and I plan to replace it with the M700s. If I understand correctly the PS Audio amps are based on B&O ICE Power top of the line (?) class D with a PS Audio mainstay analog cell front end. I’ll be running listening tests feeding them first directly from the DSD DAC and then using the DSD’s XLR outputs to a Krell preamp which I will then connect to the M700s via XLR as well.
My experience with two separate Hypex based amps (NC500s and NC502) has been that neither required the extensive “burn in” time you often read is necessary for class D. So I’m wondering why it would be any different with the PS Audio. On top of that I’ve never noticed any burn-in changes with my PS Audio DSD DAC either when new or updating firmware.
Anyone have any experience in comparing the Hypex amps with PS Audio’s implementation of the ICE Power? I’m anxious to get it all connected.
P.S. I’ve long since lost the thread on the Snowmass firmware, but I have come to like it more than Red Cloud.
