NCore Vs. Purifi

Why don't you contact Warren at VTVamplifier.com -- he builds and sells amps with both modules available and, from personal experience in dealing with him, is a straight shooting guy.

I'm also curious about this question, looking forward for the answer.

I don't have personal experience with each of the units but I'd imagine it's more in the design and how each module is built than anything. Next week I do get to hear the new Atmasphere class d amps. Very excited to hear these units myself.

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
