Arm Upgrade to Morch?

Hi Folks:
I have a Teres 245, OL Silver (with Tom's Hi-Fi Mod) and Shelter 501Mk2. I'm pretty happy with the setup, but am always keen to investigate upgrades. I noticed a Morch arm available on Audiogon, a DP-6, and was wondering whether this would be an effective upgrade over the OL Silver. I don't have a lot of analog experience or expertise, so I thought I'd get some input from some analog junkies such as yourselves. Over time I may pursue a table upgrade to something like the Teres 320, and may also upgrade my Supratek Syrah to something like the Cortese but such upgrades would be more than a year away, so in the interim, would something like the Morch be a good move? Looking forward to hearing your input. Thanks,
John.
