Welcome to the Abyss! :¬)
I've heard them on the Ragnarok, Moon 430 HAD, Moon 600i (speaker amp), Phonitor 2, Phonitor X and Violectric V281.
The 600i is the best. It's a ridiculously good combo.
@Beolab
agree's and he has access to pretty much all TOTL gear. I managed to find mine second hand for just €2500 (!). Makes the mids pop. I'm still on the stock cable by the way.
Having said that, the V281 gets close, and it's also more user friendly due to the multiple ports and whatnot. Very powerful (and will drive your LCD's VERY well indeed) and musical (for a SS amp). Not dry/lifeless at all (like the Ragnarok). There's V281 user who has a tube (Woo) amp that he doesn't use as he feels the V281 don't lack any mojo. Saying that it's still very accurate, transparent and dynamic. by no means 'tube' or 'warm'. Mojo. Hard to explain :¬)
DAC wise that's up to your preferences again. Perhaps something like the Mytek Brooklyn, Benchmark DAC3 or RME ADI-2 Pro would fit the bill without much expenditure. Just sent the latter back (as I don;t need it in my studio) but it's insane VFM. Especially if you use the Slow filter (smoother top end).
