PS Audio PWT and PWD MK II--recent acquisiton

I began a discussion of HDMI cables for I2S under the Cables heading, but my observations and questions about the PWT and PWD MK II are more appropriate here, I think. Having had some time to put this combination through its paces in my system (Modwright KWI-200 integrated, Proac Response D-2 speakers, Rel S-2 sub, Analysis Plus Big Silver Oval speaker cables, Clarus Aqua XLRs, Pangea HDMI) I'm not very happy with what I'm hearing. Yes, the two digital sources (DAC & transport) produce impressive resolution, spatial sense, and detail, but in a way that strikes me as very unmusical. In fact, though there's no discernible "glare" in the sound, it is extremely piercing and seems like it could damage my hearing if I listen too long at even reasonable volumes. 

My Cambridge Audio CXU universal player is much more pleasant to listen to even if it doesn't quite match the hyper-resolution of the PWT. I have a Wyred4Sound reclocker inserted between the CA player and the DAC, connected with Audioquest Carbon coax cables. This produces a much more musical presentation.

I'm open to suggestion here, though. Anybody experienced this, and can you suggest a remedy? My first inclination is just to sell off the PWT as a failed experiment.

I loooove my PWDII, though I use it with the Bridge II instead of the PWT.  Into my integrated, I find the sweetest spot on the volume control between 70 and 78.  NativeX and Auto filter.  Make sure you've updated the firmware to the latest.

Mine's far, far from shrill.  Keep tweaking and you just might be rewarded.

Reinstall the firmware. If you're not using the Bridge, try another firmware version (2.4.5, for example). I once had distortion issues that were remedied by simply reinstalling firmware.

If you're not using the bridge, I'd "downgrade" to the 2.0.2 (from 2011).  I always liked that one the best for the standard inputs.  If you want to try it, send me an e-mail (2.2.0 is the oldest one on their website I could find).  I thought it was smoother than subsequent upgrades and eventually quit trying new firmware.  I had to upgrade the firmware to use the Bridge II, but the bonuses of Ethernet audio overcame what I thought of (like you) as a shriller, less natural sound.
