Take a serious look at the Andover Audio Song Bird. I bought one just for Amazon music and for a while, chased the 24/96 route but found that a dead end on a budget. The Song Bird is good for 24/96 on Tidal and Qobuz right now via its analog output and the manufacturer promises the same for Amazon in the near future. The digital output is down sampled to 16/44 but to tell you the truth, it still sounds damned good to my ears. Andover says they resample as this product can be set up in a multi unit arrangement and it will help in keeping your network from being over loaded. Pardon my wording; I'm not too bright when it comes to this stuff. They also do that to make it more compatible with DACs in older and lesser advanced amps. Their software is designed by Link Play and works very nicely for the most part and is pretty intuitive and fast as hell to boot. I bought myself a small tablet just for this system and spent just $250 for both pieces. It also has the advantage of having both its digital and analog output active at the same time. I have the analog output going to my Cambridge and the digital going to its Wolfson DAC and can quickly switch between the two as a means of DAC sound comparisons, or, to see which one offers a more preferable sound given any source material or speakers I may be using. Rest assured that the Cirrus Logic DAC in the Song Bird has nothing to be ashamed of.
Another advantage is its size. I used the supplied velcro and attached it to the back of my cabinet reducing the count of additional visual cables. Unlike the Echo Link, there is no confusing source switching and is simply done in the app making the unit something of a budget preamp if needed as it does have its own volume control although no equalizer is yet available. It also has a long list of services it will play including Tunein, Iheart etc and can store favorites. The only thing I don't really like is the fact that the app won't rotate but that's not much to worry about. In the end, this simple thing sounds really, really good for the price and even an idiot like me can make it work.
