@navyachts Quality of streamer/DAC combos varies. The Bluesound units are so-so, but a good value for the money. I have a couple of TEAC NT-505 units that I really like. The newest TEAC Streamer/DAC uses different chips, so I'm not sure it's as good as the one I have which uses AKM chips. I've heard Lumin units that sound very nice. Many options.
I think you're better off buying a better unit than a Bluesound if your budget allows as opposed to adding another DAC to it. Not quite the same as putting lipstick on a pig, but you'd be better off just getting something better to start with than putting a bunch of band-aids on a Bluesound. My opinion only of course. I have tried it and speak from experience. Others may have different experiences.
