kdistefano,

Yes, the WK3700 sounds better than the WK3500. I have them side by side and have played most of the tones on each just to check. Big differences are that the WK-3700 sounds so much fuller. The sax alone is so much much better than the WK-3500 as is the piano tones. The organ sounds are much fuller sounding. If they were not better, I would have sent the WK-3700 back already ha-ha. I believe George Kaye mentioned this improved sound quality in a previous thread about the new board. Even though the names of some tones are the same on both boards the sound is better on the WK-3700. It appears they have been re-worked but there is a significant difference in my opinion.
