I am guessing that you want the liquid midrange that the unipivots can give, and the solid bass response and detail of the SME gimbal-bearing type arms. Usually you have to give up one to get the other. Except if you get an OL arm like the Silver, Encounter, or Illustrious. They are known to give liquid mids like the best unipivots, and the deep bass and detail of the best gimbal-bearing arms. They also have great musicality and are not analytical sounding. I would strongly recommend considering them, as I think they will do better than either of the arms you listed, and cost less too.
An arm to live with for years to come
I need some help from my fanatics and neurotics :-)
I am trying to fully "trick-out" my VPI HW 19 Mk IV
and now have only my tone arm to upgrade. I am torn between
the JMW 9 and 10 and SME IV and V. I just want to get the rig to the point where I can fully concentrate on software--help me I am almost there!
I have the following:
MK IV with latest Aries bearing and platter & Tip-toes
SDS
SAMA on black diamond racing cones
Grado Statement Series Reference
Steel Delrin clamp
John Boo's 2.5" Maple cutting board
AQ PT-9+ (anaconda)
