I think it's not as simple as which one is better, because the SP10's that I have heard have been some of the best playback systems I have ever heard, when set up correctly.
The obsidian base and arm should be replaced if you want to compete, or beat your excellent Well Tempered. Some of the great bases for sale on here, when matched with an excellent tonearm (Tri-planar, TransFi Termintator3, SME, Origin, etc) sound absolutely stellar.
But it will take some time and effort. The turntable is where the value is with the SP10, it's rock solid as far as speed stability, so if it's base is stable, and the arm is great it allows you to use many differnt cartridges. I have been thinking about switching to an SP10 too, even though I love my current table. Just seems like fun to match the pieces, and they really do sound stellar.
