Basis Vector vs...

I also own a Vector rev I tonearm; an excellent tonearm with superior tracking, etc. The current version of the Vector is an upgrade sonically relative to our rev 1's. I don't know all of the differences between the 2 arms, though I know the current arm uses the new Basis interconnect cable (yep, Basis is now in the cable business) which in itself would make a large & beneficial sonic difference. If there is a way to demo the current rev, it might float your boat & be an easy upgrade if you decided to acquire it.
