These would be my criteria (roughly in order from most to least important):
- Excellent objective SQ measurements (or excellent reviews from trustworthy sources).
- Roon-ready
- Supports high-resolution file processing (at least up to PCM 768 and DSD 512) and MQA
- Supports streaming and pre-amp along with DAC functions in one box (including source-selection and high-quality volume control).
- Ethernet and USB-B inputs, plus another input suitable for TV audio (preferably HDMI-ARC rather than Toslink)
- Balanced XLR outputs
- Well-designed IR remote control
- Good file-player capabilities including a USB-A or USB-C port for a memory stick or hard drive (with port preferably on front panel for easy access or else network-addressable), plus a well-designed app for file playback
- Internal power supply
- < $10K
- Good after-sale service & support (the higher the price, the more important this becomes)
- Made, sold and serviced in North America (preferably USA)
So far, I have not noticed any one product that meets all criteria. Good matches may include:
- Linn Select DSM
- Exasound S82 (no HDMI ARC?; external power supply?)
- Exasound S88 (no HDMI ARC?; includes multi-channel capabilities I may not need or want; external power supply? )
- Matrix Audio Element X2 (not made in North America; NAmerican service/support network may be relatively weak)
- Lumin P1 (not made in North America; pushes the price limit)
- T+A Series 200 multi-source player (not made in NA; no USB-B input?)
- HiFi Rose RS250 (not made in NA; no balanced XLR outputs; no HDMI ARC?)
Several products from NAD and Cambridge Audio also fit more or less well. So far, I havenāt noticed any good matches made in USA (without going to a multi-box stack, e.g. Benchmark DAC+Preamp). The new Mytek Empire seems to check all boxes but cost (~$21K+) and possibly HDMI ARC.
