RE: Have any PS Audio PWD owners upgraded to Mk II?
Posted by minimus on June 28, 2012 at 20:56:14:
The MK2 is a substantial upgrade. Dynamics are much better, soundstage and imaging are improved, and the bass is substantially better in terms of resolution and sheer quantity than the MK1 version. I use the PWD with the PW Transport. That combination has tremendous synergy. I also have the Bridge, but don't think it is on the same level as the Transport. In any case, the upgrade is quite easy to do and PS Audio provides very good customer support. At $1000, the upgrade is reasonably priced considering what you get in terms of sound quality and in comparison to megabuck interconnects and power cords that won't do nearly as much as the upgrade.
One caveat, however, is that the latest upgrade kits ship with version 2.1.0 of the DAC's firmware (on an included SD card that you insert in the back of the DAC to complete the installation.) Personally, I found this version of the firmware to sound a little bright and fatiguing -- great bass and dynamics, but slightly edgy highs. I highly recommend copying firmware version 2.0.2 onto the SD card (downloadable from PS Audio's community forum) and installing that firmware instead of 2.1.0, as it sounds a lot better than 2.1.0. Most people on the PS Audio forum seem to feel the same way, although a minority prefer version 2.1.0. In any case, it is very easy to try each version of the firmware to see which you prefer. They both sound different - 2.1.0 is fairly analytical and extended, 2.0.2 is a little warmer and with treble that is not at all "peaky".
