Innuos streamers sound great, have the best app, and offer great customer service. Here’s a used Zen at a good price, or you could get a new Pulse Mini and add an LPS from SBooster, Teddy Pardo, or LHY for about the same price.

You could pair it with this Denafrips Pontus 15th DAC and have a pretty damn strong streaming setup for around $4k. At your budget you could even add an Iris DDC (highly recommended) and get a significant performance boost for not much $$$ or add it later. Best of luck.
