As for upgrades I really can not buy into the power supply thing. It cleans up the power supply ripple. So? I hear absolutely no hint of a 120 or 60hz hum or buzz coming from this TT so this ripple is not making its way into the audio path and the platter is rock solid on. IMHO i'm thinking this may be money wasted for this TT but i'll be open minded about it if someone can explain why it would make a difference.
The damper would be interesting to try but I think at $150 it may be an overpriced mod. Between rewiring the arm, the damper etc I would rather put that money towards an SME arm if I were to think about upgrading. Not that I think there is any major flaw in the existing arm.

I'd give Kevin a call @ KAB. He's very friendly and can explain the power supply/damper mods without playing the salesperson game.
IME, I didn't try mods all at once. I ran the table stock for a few months. Then added the fluid damper. Hands down more extended bass, seemed to take out some liveliness from the tonearm, and all around sounded better. Won't take it off.
After 6 or 8 months, I did the external power supply. Since I run 12" for bass speakers, I immediately heard even more lower bass coming thru, and to me, the background was noticeably quieter. Hard to explain, sort of like noise reduction but without stripping sound/life away. Also seems to have more torque, which may also affect. The other thing is, don't most TOTL components use external power supplies?
There is some forums out there that compared the stock arm, rega arms, etc., I think someone even fit an Origin Live Silver arm on a 1200. That's tempting.

I dunno, maybe the integral headshell would make the most difference, but a rewired stock with cardas wiring for comparison? Seems like a close race, and I like the stock VTA adjustment.
Course all depends on the rest of your system, and your ability to hear the difference. I think.
