Darkmoebius/Gopher,
IMHO you really should consider retipping that 103D. If you want to, go all the way and retip it and place it in a nice wooden body. That cartridge is significantly better with the TOTL SoundSmith retip and the wooden body should be a nice plus.
I have had a 103D in my system since 1979. I have had a retipped 103D for about 6-7 years now and wish I took the dive many years earlier. I didn't because I loved the stock 103D and reasoned that I didn't want to chance upsetting it's sound.
I couldn't have been more wrong. The retipped 103D is significantly better than its stock counterpart.
For whatever reason Denon only made one 103 model with a nice cantilever (boron cantilever and elliptical stylus on the 103M). The Denon 103 is a generator assembly that needs some love in order to set it sonically free.
A lot of aftermarket hotrodding has existed for the Denon 103 models for a lot of years. Some people dismiss the 103 since its so inexpensive and others have shelved very expensive cartridges in favor of a hotrodded 103.
It may not be the best cartridge in the world but you may find it is good enough to make you stop that crazy equipment merry-go-round. At least as far as cartridges go.
I have some 320kb MP3 of some examples of the retipped 103D on my website. If you go to http://www.edsstuff.org and look about halfway down the page you'll find some links to various cuts made with the 103D retipped by VDH (boron cantilever and VDH type 1 stylus) and some with the 103D retipped by SoundSmith (ruby cantilever and optimized line contact stylus). The equipment used is also listed.
