Getting back to the original post... I finally replaced my Stello DA100 with a PS Audio DL III W/Cullin Stage III modifications. I went with this because I have read positive things about this unit with Cullen mods and it fell within my price range.
When I first plugged it in and started listening, I was a little disappointed. it was still bright, something I wanted to eliminate. I left it a few hours and came back to start listening again and noticed it was not as bright and was starting to sound the way I was hoping. For the rest of the evening I just kept playing favourite tracks from my collection where it came to the point where I had to turn off the system... I needed sleep.
For me, this was a worthwhile investment and I will sell my Stello early in the new year.
Merry Christmas to All!
