What Integrated Amp do You use

Nova Peachtree 300; I traded in a amp 4 yrs ago online to these guys cuz I couldn't afford a decent pre ever and I have been very happy with it using some pre anniversary edition Harbeth 3.01.

Leben CS-600X with Gold Lion KT-77s, paired with Harbeth SLH-5+, the sound is simply sublime.

Like some of the others, I vote for Primaluna. I have a Prologue Premium, and before that, a Prologue One. Since moving into tubes, I just can't be happy with solid state anymore. I've tried, but it just doesn't work for me. Keep those tubes a rolin', rollin', rollin'. 

Olive Naim Nait 2. A killer little amp.
