Accustic Arts Drive One Mk II v Drive II

Has anyone owned both these units? If so, how would you compare the sound. I am particularly interested in know if the Drive II might improve the highs (eg, violins) that I believe are a bit forward with my Drive One.
Yes, Dcgraves I have owned both pieces in the past. The Drive II was an improvement over the first generation transport, but a subtle % not a great change. I believe that for around the same price a used/demo MBL 1500 series transport,when used with the reference clamp, would be significant improvement and give you what are looking for. That's the progression that took place in my system.
