@metaldetektor I don’t find your comments combative. I think they are valid.
I would love to heard the NAGRA and and BAT as both use Playback digital modules. I am not sure how they stack up but am a firm believer that power supplies matter and if not separate (Jadis) heavily isolated (playback) is essential for great performance.
the customer traded the Playback because he found it a hair thin and warm in his system. The Rockna is fuller and a hair more forward. The Playback is better in mine but that illustrates that even at this high level/price, system matching still matters. You can’t blindly buy expensive components and expect them to work together.
it is a stunningly good DAC in the right system. For someone who wants a touch of warmth and a very analog, smooth sound, it is amazing.
