+1 for Primaluna.
I started with a used Prologue One and later upgraded to a new Prologue Premium. I have been very pleased with my Primaluna amps. In addition to driving my Harbeths, they also handle my hard to drive Maggie 1.7i’s without breaking a sweat. I also have a Hegel Rost integrated, which I greatly enjoy, but I I keep coming back to the Primaluna as my preference. You won’t go wrong with a Primaluna, and you’ll certainly thank yourself for stepping into the magical sound of tube amplification. (I always buy a new quad of tubes when it’s time to replace.)
