Who's using Harbeth with tubes, what speaker model and how many watts per channel?

I have SHL5+ speakers and used the Rogue Audio Stereo 100 amplifier (100 WPC).  
Amazing dynamic and powerful sound.  Much more powerful than my previous 100WPC cronus magnum II.  
Med/ large room.  
4 ohm tap sounded weak and anemic, 8 ohm tap much better.  
The Stereo 100 is actually more dynamic sounding that the amplifier I replaced it with, a Parasound a21+.  Should have stopped while I was ahead.

i had the c73s3 with the rogue audio cronus magnum ii.  one of the best sounding systems i have owned or heard, i could easily sell everything and go back, i know someone that did!  

rogue builds their amps with dynamics and slam, their trademark.  the 100 wpc kt 120s get it done.
