I had a DirectStream Mk 1. It sounded good to me but I didn't like it's streamer card. It crashed all the time. I bought an AirLens and that was a lovely upgrade. PS Audio had a trade-in deal which gave me the DirectStream II for $3500. THAT was a good deal. The 2nd iteration of their DAC is better- not exponentially better but audibly better. They are heavy - the build quality is really good. they use discreet components which is a big deal.
I'll probably buy something better in the future- the Playback Designs MPD 8 is on my wish list.
