Is there a difference in sound quality when streaming TIDAL Vs CD player

Oh, and add the Benchmark DAC3 HGC to the list above.

Don't rule out Qobuz if you talk about stream. You should try Qobuz studio 192khz/24 bit. Compare to CD, it is day and night. Try it yourself.

I personally would be scared to purchase used speakers.  How does a novice even know they are in perfect condition?  Why is the party selling them getting rid of them?  That would indicate they were not satisfied with the sound quality.

I wonder if anyone has ever heard a pair of SALK Song3 Encore speakers?  For $6,000 they were much better than a pair of $60,000 speakers I heard at the RMAF.  They are certainly better than any of the Focal speakers I have heard.  Obviously, no one in this discussion group thinks much of Focal otherwise you would constantly hear people bragging about how great they are.  They are also over priced.  However, I do like their tweeters and their mid voicing.  I think they are designed to hear classic music and vocals such as Diana Krall or choral music.

“Why is the party selling them getting rid of them?”

I wouldn’t be worrying about this too much. People change / upgrade / downgrade components for various reasons. The key is to read available specs and reviews for the component or speakers you’re considering before you make a purchase. Next thing you need to make sure that used item has no operational or cosmetic flaws and what’s being included in the sale. 

SALK Audio makes great speakers and are reasonably priced. I am not sure about the analogy of $6K vs $60k....i think this kind of broad generalizations ( like any Focal speakers ) is too vague and carries no weight. I personally don’t care for low end Focals but once you get upto mid to high range they are pretty good. 

You find Focal’s overpriced, no argument there but so is everything else that carries ‘fat’ dealer margins. Plus Focal’s are being made overseas, so one must account for import duties and freight costs. 

I've sold at least a dozen mid-fi pieces of equipment in mint condition including McIntosh MX110, Fisher 1000 preamp, Acoustat Xs, 2&2s, Martin Logan Quest and Monolith IIIs.  The reason, I purchased something I liked better.  I did purchase my current Legacy Focus speakers defective in that the prior owner rewired it but left out the mid-range insulation so that the speaker was very bright and forward for brass, upper voice and upper strings.  Yuk.  It took a few years until I found the problem (I used other techniques to alleviate some of the brightness) and stuffed the cavities with ample damping materials.  Now it sounds smoooth in the upper mids.
