OP -
It took me years to find a transport that could replace my Audio Research CDT-1 . I had upgraded my DAC to a Bel Canto 2.5 and it opened up my ears, but something was missing. Call it a leap of faith, but I bought my PS PWT and never looked back. I eventually sold off the Bel Canto DAC and got the PS DSD ( w/bridge ) so I could take advantage of of I2S connection and improvement in detail, soundstage, foot tapping & emotion ( mine ) was astounding.
Like you, I have upwards of 2000 CD's and re-listening to my personal reference CD's and many others makes me want to suggest you keep your PWT and contemplate mating it to a PS DSD. I know you might find it hard to let loose of your,
Aesthetix Pandora SIgnature , but PS will send you their DSD for a 30 day listen and if you find you want to keep it , they'll give you a fair trade in for your DAC.
In any event, happy hunting and listening and letting me share my opinion.
