Heh, well the price point won't
be going any lower. As I said before, $2K is generous if we're using the term "high-end", pretty much the only reason I did that is because I'm aware of quite a few sources between $2K-$3.5K like the Electrocompaniet ECD-1 (owned by krmathis) and the Arcam FMJ CD36 (owned by HiWire) that don't really deserve to be cut off from a list like this. If that has to include sources I don't think are high-end like the SD Transporter then so be it.
(But at least the SD Transporter uses a pretty good DAC, the AKM AK4396.)
The many sources punching in right at $1K or just above (Benchmark DAC1, Lavry DA10, PS Audio Digital Link III, Apogee Mini-DAC, CA Azur 840C, NAD M5, et al) are not high-end, those are either studio-grade or just products that think they are, so there!
