I have a PS Audio DSD Mk1 and ditched the card for a separate PS Audi AirLens Streamer. Night and day difference. The card was a pain in the arse- dropping signal and needing to be rebooted all the time. Plus the sound sucked on almost all music. I really like the SP Audio DAC so I threw the dice and bought their new streamer- game changer for sure! I'm not in a hurry to upgrade my digital front end yet as Moors Law tells me that in 2 years the product offerings will be 2x better and 2x cheaper.
Now if you have the itch to buy something with some money to burn and don't care about the deprecation buy the Bricasti.
