Certainly try them both, but know that the folks at VPI are big on Dynavector carts. I got a Scout back a month or so, had a few email exchanges with VPI which had me headed towards the 10x5. Then I also picked up a another VPI higher up the model line instead and went with a DV 20x2-l instead.
Funny, I had an old V-15 with little use I was going to try, but when I pulled it out of storage I found the diamond had come off the stylus, pity. If you do try the Shure I'd be interested in hearing your results.
