Ah, I see what you mean about the thread now.
Yes, I had a chance to compare before I decided to swap. I found it was a lot more noticable at home in quiet surroundings playing all the songs you were used to hearing than in a noisy dealers show etc.

But the other factor was losing one slot if you filled one with ew65 card. If they had sounded identical I may have just got the card instead, but then you couldn't fit both 01 and 02 cards.
I have hooked up all sorts modules and samplers and other boards in my time, but at the end of the day it is just so convenient to have it all built in, instantly available, and instantly useable in any part when inspiration strikes, if you see what I mean. So the other cards played a part in my personal decision.

hope you get some good tunes on your big day
