Leica man,
First of all you should be spending money on an M8 and lenses, rather than this audio junk.... (Okay I'm kidding, I'd love an M8 but just ordered a whole new front end, as you will read)
I also presently own the WTT and arm. It has served me well for many years, and recently ordered (but haven't yet received) a Raven One, Phantom arm, stealth hyperphono cable, and Tron Seven phono pre. Now you understand why I am taking pictures with a cellphone and not an M8.
I am hoping that the new table/arm/cable combo yeilds a massive upgrade in sound quality and enjoyment, or I will feel like a complete fool. Feel free to contact me in a month or so to see if the upgrade was worth it (if not I may not be reading emails from the outside of my window ledge)
That being said, I always felt that the WTT arm, as good as it is, can't be set up perfectly. I think the floating design prevent me anyway from really getting a perfect alignment (which probably few can accomplish anyway, regardless of arm).
This is the main reason why my choice of cart was the Sumiko Celebration. Thier design goal was to allow excellent sound despite lack of perfect setup.
You may want to look into that cart, especially if you are going to live with the WTT for a while. The other nice thing about the Celebration is the price point. It was made to compete with carts twice the price.
