No, no, no. Terrible trade. The 704 is a terrific sounding arm that is additionally very rare, collectable and worth a bit of money. It is much better built, and sounds much better than the 707 as even a cursory inspection will show you. It works very well with medium compliance cartridges of any stylus profile. The crap about unipivots being good only for conical stylii is utter rubbish. Current unipivots include the Graham, Immedia, VPI and Morch. All selling for over $1000.00. It would be foolish to think that these could not be used with modern cartridges with their advanced sylus shapes. Feel free to contact me directly before you get taken to the cleaners. BTW, the DP6000 is one of the great, classic tables; you have yourself quite a nice setup. With a little tweeking it will sound very good.
