So I have owned, Ice, Ncore, Purfi (NAD China licensed) and ended up going back to Class A A/B. Norma Revo IPA-140B.
I found them all very lacking in depth and soundstage. A bit bright (speaker pairing more than likely the issue). Great detail but not enough to over look other deficiencies.
Looking to try a GaN Class D from GATO.
I am not condemning Class D just did not work in my audio ecosphere.
My Daughter-In-Law has a Kick Butt system that is all class D Merrill Audio and Sf speakers and it sounds awesome. My Son says it's just a stereo to him...LOL
