I never heard hear the Audio Aero, but I did own the Tri-Vista SACD Player and would say that it is a great CD Player with a sound stage and imaging that is full and deep. But like a fool I traded it for a Mark Levinson 390s, because I wanted something that matched the rest of my system. That was a BIG mistake, a very BIG mistake. The 390s just can not hang out with the Tri-Vista IMHO. And Im only talking red book CDs.
If I could make a deal for another Tri-Vista, I would in a heart beat.
