Suggestions for Thiel and Conrad Johnson tube amp

The Thiel CS6 and Stratos extreme monoblock, is
world class match, the musicality and the
listening level is so high,when I took the
stratos to my friend and hooked up his x250,
He cant even listen to it, It was so obvious
that the music jump out of the window.
Even the Krell 300 FPB,and Thiel with good
front end did not match the musicality of
Thiel and Extreme.Try first before you buy.
IMHO
