laid back stereo power amp

The Van Alstine Vision SET 400 is about as good as your going to get at that price level and a match since you have Frank's preamp.  $1999 for the black version with a 30 day money back guaranty.  The Odyssey is also a great option with Maggies but Klaus' build time is months nowadays.

I think you'll like it as I've enjoyed mine since the first of the year fronted by the Supratek Chardonnay.  

I've owned four different Odyssey amp models over the last 20+ years and wonder if he has actually ever heard one.  Audio Research are anything but warm and fuzzy tube amps and the Odyssey amps would even be smoother than many of them.
