Better Amp for Cornwall IV's...

Pass Labs Aelph Zero Class A monoblocks work well with Klipsch. I have 1974 Heresy and LaScala

You mentioned an open box unit from Crutchfield.  IIRC, they will let you return within a reasonable length of time if you don't like it with your speakers.

I'd sure want to make sure I had full return privileges before going that route.  It was discounted pretty heavily (almost $400), so that would be a good way to try one and at least see if I liked it.  And if not, or if it was a little TOO scratched and/or dented, let them have it back.  But...I'm always reluctant to return anything unless it's pretty bad.  I shouldn't feel that way, but I do.

"You mentioned the DCD-1600NE.  I just received the Denon DCD-A110 SACD player and I'm so impressed with it that it has me thinking about buying the matching integrated (PMA-A110).  In other words, I think your experience with your SACD player will mirror the experience you'll have with the PMA-1600NE.  I wouldn't hesitate for a second to buy the Denon amp if the quality of Denon's other hi-fi gear is any indication what to expect."

I can only imagine as to the build quality of the A110 products from Denon.  Must be in Luxman and Accuphase territory.

I would just go with fewer, higher quality watts.
Something operating entirely class A in solid state or tubes.
