"Bullot",
Congrats on the new amps. The Vitus amp are indeed very very good. I'm using them as well and have had the 33H in the past as well :). After the 33H I upgraded to Dartzeel, which I liked a lot too before moving for the Vitus SM-101. Think the Vitus has the best of both Dartzeel and 33H together.
Happy listening
