I own one, use it with an Audio Research VSi55 integrated and BMC Purevox speakers. When they came out they were $499 originally. Now under $300 they're an even better buy. Build quality is great, no issues, sounds great. I was originally lusting after the Line Magnetic Dac, an $1800 unit, but in a side by side comparison I couldn't hear any difference between them (this was using the LM's solid state output; the LM's tube output does sound different but also has higher voltage = higher volume, making direct comparison difficult using the tube output). So I opted to save the $1500+ and go with the DacitX instead. I wonder if potential buyers see the low price and assume that if it sells for so little it must not be very good, but that wasn't a problem for me - if I can get $1800 sound quality for $300, I'm in.
What speakers will you be running it through?
