I got one for $135 new.
the original price was $600. and it is not a recent product, it was released about 5 years ago, which explains why it's a bit outdated.
the performance can't be explained that way though
my experience with it is the same:
- lack of power:
headphone out is very weak
but I expected the line out to be less than 2V because JDS Labs OL DAC seemed louder to me
- horrible drivers
although ASIO works reasonably well for me (until I skip too often and it crashes)
windows system sound can break if the frequencies don't match i.e. DAC is at 44.1k and the sound being played is at 48k
the real advantage of this DAC is that it can play DSD natively without DoP etc. I even managed to set it up to work in foobar2000.
I wonder how good the measurements would be without those suspicious spikes.
