After listening to each of them for about a month, I preferred the RS over the PS for my taste (genres) The PS is a beautiful sounding headphone, and I'm very glad I got to spend the time I did with them... but going from one to the other I just enjoy my RS's due too their more upfront presentation, and don't feel the need to own both. I'm also going to contact Woo and see if I can exchange the 6-SE for another WA6 so I can use the 6SN7 tubes, believe it or not! I really miss the 596/6SN7 tube combo I had with the WA6/RS1i's.
I never heard anything that I liked better, and left me in such an amazed state after listening. So I'm sure to most, it seems I'm going backwards, but thats not what my ears are telling me.
I was where I wanted to be before going nuts with all the "up grades" and just didn't realize it until it was gone. So I'm going back to where I was the most satisfied, and being true too myself.
