I have been using a Sonic Frontiers Line 2 with both Bryston 4BST and a BAT VK655SE. No issues either way. Both sound wonderful, but different. The BAT lacks the imaging and impact of the Bryston. Yes i was Very Surprised especially about the dynamics. The BAT is mellower and maintains it's composure at very high dB's. I am driving Maggie 3.7i in a large room with high ceilings.
Tube Preamps that work well with SS amps?
I'm looking for a tube preamp after years of strictly SS. My amps will remain SS. Which tube preamp(s) in your experience mated well with a SS amp? I'm trying to avoid the odd phenomenon where tube preamp + SS amp = slow, soggy sound in spite of benign impedance characteristics
