The Space Arm is a good match for the 17D2. It will handle the XX-2 adequately but to fully realize it's capabilities a better tonearm is required. The Space Arm, however, is clearly superior to the JMW-9.
Dynavector 17D2MKII vs. XX-2
I was curious, if the performance gain is worth the extra money, between these carts. I went from a 17D2 to a 10x5, and man i'm missing the 17d, i'm considering at least moving back to the 17d level, but am curious if i would gain much by moving up to the XX-2, any opinions or comments would be great. thanks.
