And it does not sound as good as Tidal or Qobuz.
This is not a unanimous opinion.
Unanimous meaning most people do not agree? I tested it out for a month and found the Amazon delivery of music to be less detailed and missing clarity that I found in both Qobuz and Tidal. Spent hours A/B'ing the same tracks and albums. This was on all gear I own across wired and wireless sets, amps, and DAC's. Seems to me most on these forums agreed with that opinion but yes, it's just my opinion (or fact to my ears
. Using Amazon or Apple would be a tad more convenient for me but...
Well, it might be when you did the A/B comparison Amazon wasn't as far along in their rollout as they are today. Now I find AMHD compares well against Tidal Hifi non-MQA or MQA, some recordings are better on Tidal some are better on Amazon.
Early on both Tidal and Amazon had Windows App problems, Amazon more problems than Tidal. Amazon Music HD and App improvements have greatly improved AMHD's usability and SQ.
And, both Tidal and Amazon catalogs have many of the same core publishers, but many fringe recordings are on one or the other, but not both.
I find having both beneficial, I've already got Prime - and now Amazon HD Music is even cheaper since Amazon folded HD down into the base charge - only $7.99 for HD instead of 2 charges totaling $12.99 per month.
And, while Tidal Hifi charges $19.99/mo direct, I bought an annual pass from BestBuy almost a year ago for $89.99/year ($7.49/month) -
now $99/year - that renews after the 1st year for $119.99/year ($9.99/month), so my monthly cost for both services is $7.99+$7.49=$15.48, until September when the charges rise to $7.99+$9.99=$17.98
And, I have 2 catalogs of music to draw from, if I can't find something on Tidal I go to Amazon and usually find it, and Amazon HD sounds great to me.
BTW, I'm using a Topping D90 MQA + Topping A90 => I've now mostly replaced my A90 by the Xduoo TA-20 Tube/Hybrid for most of my listening, with some mobile listening done with my phone + Hidizs S9 USB, or FiiO BTR5 BT, or FiiO M15.
