I personally did not like the combo. Everything I read speaks to the Denon needing a very heavy arm, the newer SME arms are simply not made to work with these types of low compliance carts.
Denon DL103 and SME IV arm
I'd like to correspond with someone who has used a 103 with an SME IV or V arm. I just happen to have both. I know there're lots of 'experts' who don't have any experience with this combination, and that's why I want to hear from somebody who actually used these together. Mine required the use of about 1/8" of spacers when mounting, which seemed like a good thing since vinylengine says I need a few grams of weight anyhow (added up to about 5g), and now I am 'tuning' for performance. So far I am impressed with tonal quality even next to my 901 ii cartridge on main setup, but my lps seem to have more surface noise.
