I think it runs as warm as you'd expect from eight KT88 tubes. It's warm if you hover your hands directly above the tubes but not in an unusual or unexpected way. Heat has never posed any issue with this gear. I run the Gold Lions and I'm definitely happy with the sound especially for a $4K amp. I ordered mine upgraded with the Mundorf SilverGold caps and Hexfred rectifiers.
On the topic of warm, I have also heard that this amp in particular can run very hot. Have you had that experience?
