I agree with Jaybo. You already have a $2,000 arm, and Origins are generally considered over-achievers anyway. If you have $1K you *must* spend, I'd say get a nice cartridge. You wouldn't be stretching beyond the Encounter's capabilities by any means.
But if you want to make big tonearm improvements, save your money until you can get a Graham Phantom.
