VPI Classic---Denon 103 won't fit on arm??

I have a 103 mounted on the standard 9" arm and it is hard to see how the 10.5 would be different. Contact VPI and make sure,

It works well for me, the compliance of the 103 is not that low. The tests of it in the 70s and 80s recommended a 6-16 gram mass arm. I have seen the classic Japanese detachable head shell arms of 20 grams + recommended on the grounds that the arm will flex more with them. I cannot see how that is a good thing, arm rigidity is more important with MC than MM. I owned many of the old arms when they were new, FR 64, several ATs, Luster 801, Micro Seiki 505 etc. and would rather have the VPI arm. I see questions about the VPI being a unipivot but there are several other top arms that are unipivot which are used with moving coil extensively. I also have an Aries with 12.7 that I use with a Denon 304. That sounds better than the Scout or Scoutmaster with the 9" arm and 103 but it dammed well ought to considering price differential. As a VPI dealer I picked out the 103 because I think it is good enough to give an excellent sound with the tables but not at a high cost. I am not a Denon dealer. The Dynavectors will give an improvement at a much higher cost. I am a Dynavector dealer but in this economy I am trying to put together a vinyl system that can be had at the most reasonable price and allow for cartridge upgrades later if desired. I recommend Bob's Devices step up transformers for MCs, major bargain. I have no connection with them except using one.
