I own both a denon 103R and Koetsu Rosewood and the denon 103R is superb. The denon 103R plays rock n roll better than the Koetsu as it seems to have a little more weight in the upper bass/lower mids, the Rosewood has the slightly more magical midrange.
If your TT and phono stage is up to the .25mv output, go for the 103R.
