ARC Ref 75 vs. Ref 75 SE

Co93: I believe what you are hearing, in the ARC REF 75se, is stability. The "new" sounds you are hearing have always been there but the instability in your former electronics was masking them. I'm not an EE, so I can't explain the particulars, but when we finally get ultimate equipment it will give us a feeling of natural stability. I think this is the biggest part of the new MQA technology. Mr. Stuart keeps referring to "temporal smearing" and how MQA eliminates it.

Dweller.   Take note, it was all done on vinyl.  Same gear except for the amp,  same album....  MQA is a digital thing, isn't it?

I guess it's obvious dweller is not an EE?

Um, same problem different medium. Sorry I didn't spell that out for you.

Same problem?   Didnt realize vinyl had a compression problem...  Imagine that.  I learn something new every day!  And here I thought it had something to do with the larger electron plate in the KT150s...
