PrimaLuna 300 pre with Pass XA25 power (25W pure class A). Very happy with it, but don’t have a lot to compare it to. The most I can say, acoustic instruments I know well (viola d’amore) sound spot on: recordings by performers I know and have heard live or with whom I had the pleasure to play. But also listen to assorted ...-wave, and electronica, EBM.
I may like slightly smaller volume steps at low levels on the PL. I have not gone into tube rolling, so that is another avenue to explore. I use the Pass with 8 ohm/87 db speakers in an 18' room, listening at low levels (say 65-75 db on average). I added a REL T9 for slight bass extension for the Sibelius SG speakers.
Hope that helps.
