I am thrilled with my system and my amp is an integrated Primaluna Evo 300 (all tube). The tubes made the difference though. Up front I have two sets of Radiotechniques and 1 set of Brimars. In power I have a set of KT-150s and a set of GE 6L6GCs. With 4 KT-150s I was missing out of quite a bit of "mid range magic" and with for 6L6GCs the mids were a little shouty and didn't have enough power. Mixed they are incredible together.
Speakers are Volti Rivals.
With the right record/recording/pressing, I truly want no more out of my system. There is always better but I'm more than content with my setup.
