@larsman, I have a Holo May KTE DAC that is sourced by an Aurender W20SE for streaming and music files. I also source it with a PS Audio PST SACD transport. I also have 2 turntables, a Linn LP12, Radikal PS, Keel subchassis, Ekos SE arm, and a Rega P10 with Apheta 3 cartridge. I’ve had my Enleum 23R for just over a month now and I couldn’t be happier with it.
The VO on the 23R is much better than it on the Nirvana. I considered selling my VO until I heard it driven by the Enleum. I love my Nirvana but the 23R is the best amp I’ve ever heard. It brings out the best in everyone of my headphones, but not only that, it’s a fantastic amp for high efficiency speakers. I’m floored how good my Klipsch Cornwall IVs sound driven by the 23R.
