Bigkidz,
My uncle is good friends with John, I've actually had dinner with the gentlemen. My uncle had my old Bitstream and was able to do a direct A/B vs my new Bitstream. These are the impressions sent to John:
"At first and on newer, or well made recordings the differences were minimal. After awhile and especially on older recordings (The Essential Leonard Cohen by Columbia), the newer dac was more detailed, smoother and had an even greater ease. Sibilants disappeared. Just a more refined sound overall. Nice work once again. Congratulations."
I haven't done a direct A/B because I don't have my old DAC on hand. However I don't blame you if you don't want to upgrade your DAC, I wouldn't want to. I simply had an opportunity to get a Bitstream back and I took the opportunity as I had cursed the day I had originally traded for a Benchmark of all things. I can honestly say that out of all of this I've learned an important lesson. Don't replace Bitstream because you might gain in one area but lose in many others. The new Bitstream is as analog sounding (or more so) as I had remembered with my old one. Again merely working off memory.
