Pros: Great sound for the money
Cons: Only one of each type of input
This D2A delivers great music. I use it to play back music (regular and hi-rez files) through my Juli@ card as well as Spotify streams via my mobo's toslink port. The M1 looks nice, sounds great, and doesn't cost an arm and a leg.
I tried a Shunyata Venom power cable out of curiosity, fully expecting no difference to be apparent. I was wrong. I noticed an increase in intelligibility - lyrics that I couldn't understand before now were intelligible. The noise floor, which I hadn't noticed anyway, is now lower, too.
My only complaint with this unit is there is only one of each type of digital input - my universal player has no toslink output so I can't use it with the M1. I have to use the S/PDIF out of my Juli@ because the toslink won't pass the 192/24 files I got from HDtracks.
I guess I have two: This unit is first generation, before they upgraded the USB input to an asychronous one.
