Radio Design Labs HR-DAC1 High-Resolution 24-bit/192KHz Digital to Analog Audio Converter - Perfect for Home Theater, Music Production & Audiophile Listening

If you can find a used one at a lower price, you might choose to get that, but it's an excellent broadcast-quality ADC with all of the inputs and outputs you're likely to need. And the controls, while small and hard to read for old eyes, are easy to use and do pretty much everything you'll need.One reviewer noted that it doesn't come with the necessary 24V AC power adapter. You can either get the PS-24AS made by RDL (https://www.amazon.com/dp/B00AQUZBIK/, currently $31) or pretty much any similar adapter for a lot less.
