Dan, I am a die-hard unipivot guy with some low compliance carts, so I am a bit concerned by your post. I have just bought a 12" Sheu Classic (14 gram unipivot) and am planning to run my DL103 on it. What type of problems are you referring to?
I have been a long time Morch UP4/Koetsu user, and ever since I started using the 14-gram arm the sound has been nothing short of jaw dropping. I would be very disappointed if the Denon 103/Sheu proves to be a lame duck.
Thanks
Paul
