Pass Labs XP-12 Balanced Pre Amp Aug 2023 I purchased the Pass Labs XP-12 Not a lot to say about this one, which in itself speaks volumes. It has a multitude of SE/Balanced inputs/Outputs, is well made, feels solid and quality in use. The sound is sublime, having great synergy with both my digital and analogue sources. It pairs well, with my Neurochrome Modulus 686 Monoblocks. I don't feel the urge to change anything, which must be a first.
