I agree- in my case though I kept one of the DD-2's (same as big chip DD-3) and got a DD-7 for all the other functions, great combo. Never had a chance to try a DD-5, but the DD-2 is the perfect sounding digital delay to me.Keep a DD3 and sell one for a DD-5 or DD-7. DD-7s are ideal in terms of functionality. But IMO, I think the DD-5 sounds just a tad better. That would be something you'd notice as a musician however. It's not anything that the audience can tell.
