I spoke to Mark yesterday,he was very helpful in suggesting amps.
I'll call Craig at NOS and ask about the st-45 ,I don't see it on his site.
Basically I'm lookin for that dynamic,punchy drive that ss can deliver,lean and mean for the low end.My concern with another tube amp is the bass,It was really a revelation to me ,after 15 yrs. of tube amps what SS,in this case a MC122,can do when matched with my Corns.
My thought is that the BB would warm it up just a tad...the Klipsch,to my ears,have this "real concert" sound that I love,especially on "live" recordings. Van Morrison's new LP has one side that is from one of his live concerts and it really sparkles. I just saw him in NYC a few months ago...best sound I ever heard at a concert. It was a 5 or 7 thousand seat church,the sound was slightly warm,smooth yet powerful and dynamic.
