I am not an expert on Oracle turntables. But Well Tempered yes! The Well Tempered arm seems to be one of the hardest things to set up correctly for most turntable lovers. They simply do not commit to tweaking, and tweaking it until they get it right. When correct, it will "sing" like magic.
I use a Denon 103R on my WTT, and it works great. Not as smooth or emotional as a better Shelter 501 cartridge would be, but for the dollar spent, I would take the Denon over the Dynavector. I also listen to Steely Dan and lots of 70's rock.
Denon discontinued the 103, so your only hopes are a used one. Be careful of cartridges that have been laying around for years in a box somewhere. The cantilever is usually all stiff and worthless. Personally, I hate the thought of buying cartridge used. Speakers are almost as bad. Electronic gear either works or its broken. Speakers and cartridges could be damaged, and it may be hard to tell.
Good Luck
