For sale is my PS Audio Perfectwave Dac MKII with bridge in silver.  This is a factory MKII and not an updated MKI. It is is excellent condition and the top plastic has never been removed.   Original purchase date 5/2012 Priced to sell at $2250 + shipping + paypal fees.

I wish. I would love to try this.
I'm going to continue doing my research while waiting for the new firmware to be released.  If it isn't a real improvement, I'll let it go.  The software issues are a problem.  I want to listen to music and not fiddle with software.  
I think there are so many PWD's on agon because of their firmware issues.  Some firmware sounds good with 1 vintage of PWD but not another.  Some vintages will play only some of the firmware revisions.  In buying a new one be sure to ask which firmware works.  When I first received mine it sounded horrible.  I reverted back to a prior revision (with some difficulty - had to seek out a PSA engineer) that wouldn't load on my hardware.  The newest firmware is improving and...
