My advice - move on - I did! My DL-103 now sits quietly in its box after hours upon hours of trying to find the magic some seem to have found with it.
I think the Ortofon Red will be a much better match to your system and is a more well-rounded cartridge than the DL-103.
Don't get me wrong - I understand the infatuation here and over at AudioAsylum with the DL-103's midrange, but I could not live with it long-term in my system (KAB mod'd table, PS Audio GCPH phonostage, PS Audio GCC-250 control amp, Usher X-718 speakers). As you put it - it never sounded "right" to me and I found its midrange colored despite others opinions to the contrary.
The 640P is a very good stage for most carts, but I've read that it's a horrible match to the DL-103, so I'm guessing this only added to your problems. It should, however, be a stellar match to the Ortofon. I've heard the 2M series of and they are very very nice indeed.
I find it interesting that alignment became such a focus of discussion on this thread - the conical stylus of the DL-103 is probably the least sensitive to alignment issues of any cartridge I've heard in my resolving system.
