WOW. Did I set off a storm!
I appreciate all the advice guys (and gals if any are involved). Being quite pleased with the Schiit Bifrost 2/64, I queried Schiit as to whether I would be able to detect a significant difference between the Bifrost and the Yggdrasil, and their surprising answer was "no." So, based on what I have read here, I am going to start by replacing my streamer and going to either Tidal or Qobuz (I need to check them both out). One key criteria I have in my purchases now is to avoid buying things from the PRC; that is not to say they don't make some good stuff, but having spent nearly four decades as an Intelligence officer, I see China preparing for war in the Pacific, and I don't want to contribute--via taxes on their companies--to the Chinese military in any way. Having said that, I realize that such a position radically constrains my choices in a streamer. One brand I have found is Innuous, which makes their streamers in Portugal. Given that my budget is around $3Kto $4K for a streamer, I am thinking of the Zen MkIII, which can rip CDs and has a linear power supply. The Pro-Ject S2 Ultra has some ambiguous reviews, so I eliminated that. Are there other non-PRC options out there?
As for the streaming service, I like convenience, so between Tidal and Qobuz, is one more convenient to use than the other?
Finally, thanks to all who commented, and I can see that there are those who are even a bit more passionate than me about this business of getting the best music reproduction possible within certain financial constraints. )Fortunately, we live in a still free country, and people are entitled to their own opinions.) I think I am pretty close to what I can achieve within my financial limits. Thanks again ... to all who commented.
