don’t be - they are for real... i have tried many if not all of the contenders in the $500 to $2000 range... mhdt makes several models based on r2r nos chips, all w tube output, even their more expensive models can be found used for under $1000 - but when they appear on audiogon or us audiomart, and are snapped up pretty much straight away
jolida/black ice, as mesch mentioned, also makes a tube output dac... also very good (but not quite as good as the mhdt’s)
frank van alstine/ava also has made excellent dacs less than a grand in cost, with tubed output stages that sound very natural
if you do research you will also see mention of a border patrol tube dac around $1000 used... i would suggest you pass on that one... the tube is used in the power supply section... not in the output stage, and its sound quality, while good, does not represent as good a value as others mentioned
there is also a chi-fi dac by musical paradise that is tubed output -- it has seen some good reviews but i have not tried it in my own system (i personally lean against direct marketed chi fi stuff as there is questionable support if anything goes awry...)
bear in mind also that to get a full, natural ’more musical presentation’ than the more common treble-centric robotic-sounding dacs, using tubed output is not the only solution -- ayre codex and metrums octave/amethyst are two others that provide an ’analog-like’ sweet and dimensional sound profile under $1000 used...
good luck have fun happy holidays
Anyway, I’m not sure how this translates to the HiFi world knowing that we all want clean / clear power for our listening. But when I see tube dacs for $500-$800 I’m skeptical.
