Sailormike:
I had the MD1 / SBP32x combo; traded in the SBP32x for a 64x and felt the differences were very pronounced; smoother high end, but the bass with the 64x was incredible. I next tried adding a Genesis Digital Time Lens and really didn't feel there was much of an improvement to my ears. Not too long ago I traded the MD1 / 64x combo for a KPS-20i, which I absolutely love. There seemed to be a bit of an improvement with the bass using the 20i, but the treble was a vast improvement.
I can't speak for the KPS-25 or the Reference 64. Also, I don't believe that Krell offers an update from the 32x to 64x (at least they didn't when I owned the 32x).
Happy listening, Ron
