? Integrated amp, rich warm midrange, tight bass

Strange, I think the Portal has amazing warmth in the midrange, compared to NAD it was night and day. I wonder if YBA would do the trick...

Not familiar with your speakers but I also use a Portal Panache and agree completely with Rtilbury. For reference I've owned integrated amps from Audio Refinement, Roksan, Harman Kardon, Denon and Sony. The Portal and the Sony TA-F707ES have the sound I prefer. After having the Portal in my system for a few months now the aspect I've come to appreciate most is how well it maintains its character at low levels.

There is currently a Jadis Orchestra Reference (~50 watts with KT-90 tubes) listed on Audigon (not my listing by the way) for ~ $1700 which you might want to consider. Some people say that particularly with KT 88's its mids are very lucious- warm and liquid.
