There's a lot of choice these days, what input/sampling rates/output do you need. Personally I like AES/96..24/Balanced so the Lavry DA10 works for me. There's loads of good network players that do it all up to DSD and come in cheaper than standalone though.
If anyone is after a reasonably priced DAC, I am selling a Beresford Caiman II. It kicks dicks - read the reviews.
All the connections you could ever need plus fixed/variable output so it can double as a pretty good preamp if you don’t use vinyl.
