My dyna XV-1s was perfect out of the box. Had it for three years and probably 1,000 hours on it. Recently in last two weeks started noticing soundstage shifting, increased sibilance and maybe some crosstalk. Tonal quality still perfect though. When I started investigating, I noticed the cantilever shifted about 1 mm to the right - very subtle but there and definitely new. And, no, I have never luckily had a cart mishap. Through further investigation I noticed that my turntable platform has settled in the floor after a few years and was now about 1 degree lower in the front end and not level. I am afraid that combined with insufficient anti-skate may have led to the problem. I just like my sound with little to no anti-skate: I think it thickens the bass and detracts from natural rhythm and pace. Not sure if Dyna carts are more prone to having the cantilever shift to right over time or not....

Good idea, I may go with Chong to take a look. But you are right, I'm always looking for an excuse to upgrade! Ha! But one never knows when upgrading if it really is one sometimes hence my curiosity of anyone with Xv-1s, Xv -1t and Transfiguration Proteus experience.

I really like my TW arm. I have tried VPI (didn't really like) and Graham (good but more solid and realistic imaging with TW) and felt that the TW arm was superior in my system. However, I am sure mileage and preferences may vary......
