Step-up from Node2i for native AmazonHD streaming?

Have you tried Qobuz? If you do some searching you’ll find Qobuz hi res is generally preferred over Tidal. I don’t doubt that the E30’s are a great value, Topping is a brand that punches above its weight class. I was only commenting on the logic of pairing a low cost budget DAC with something along the lines of the M30.

I haven't tried Qobuz. I was using Tidal HQ for about 6mos when A-UHD launched, and switched. I don't notice an SQ difference between the two. A-UHD plays nice with all our Echo devices, NAD (w/BluOS2i) and Denon AVR (also Echo-controlled). With the family plan, we frequently have different music playing in different parts of the house - all works without any problems. Actually, the only problem occurs when Alexa (for unknown reasons) occasionally tries to access discontinued Tidal subscription, "Can't play... on Tidal at this time, login to authorize...". I think this is a remnant from the expired subscription. Asking again usually solves the problem, and it plays from Amazon.

Questioning the choice of Topping E30 DACs opens other options.

A matched pair of stereo DACs is required. They need DAC-only function, but could also have pre-amp features and headphone amp; however, those extra features will not be used. I haven't purchased the DACs yet.

Topping nay-sayers: A pair of E30's cost $260 (new and not on sale). I'm not opposed to buying used. What other pair of DACs would you recommend for $300/pair and where do I buy them?

All other DAC/system budget pro's... I'm not opposed to spending more, for better performance if value is still there. What is the next least expensive (even used) pair of consumer-grade (plug it in and it works) DACs that are UNDENIABLY better sounding OR measure better than E30, make/model/version, and where can they be purchased?

@djones yes, I’ve seen the Amazon list before, and figured my best bet was Sound United group. Denon doesn’t seem to have anything (didn’t look through the AVRs), Marantz has so many models - I looked through a few categories and didn’t find anything, all the others would take forever ruling each brand out one-by-one.

I was hoping the community would know gear capabilities better than I - that might not be true. I may have to buckle-down and create a spreadsheet for this search.
