Forget Triplanar and the like, you have to go with an arm that has high effective mass. I have real experience with many arms and the 103R, including Triplanar, Audiocraft 4400, Micro-Seiki Max 282, Sony PUA 1600L, Lustre GST 801, SME V, and Fidelity FR64x but the winner by far was the Ikeda 407.
In this arm the 103R comes alive and for me the paradox was that this was the only cartridge that this arm seemed really happy with, including other low compliance carts such as Koetsu. I sold the Ikeda because I never could get it to sing with anything other than the 103R and this was clearly an economic mismatch.
The performance of the 103R is equally defined by the impedance loading and either you use one of Denon's step-up transformers or something that that has a 40 ohm impedance load. If you put a 103R straight into a phono stage without transformers, the cartridge will be nice and tubey, but lacking in sparkle and detail that it is truly capable of.
The Denon is a giant killer no doubt for the price, but, IMHO it is not the final word either. It cannot compare to the likes of a ZYX for transparency and impact, nor to the likes of a Sony Xl-55 for slam, or to a Miyabi for tone and emotion.
In my collection I really admire the 103R for being sublime and faithful to old jazz albums. mono recordings and classics from the 60's. I use it on my SP-10 Mk2 and despite the trade offs, I always find it delivers a satisfying performance. There is no perfect cartridge / arm combo, so I just accept that the 103R is not the total panacea, but it does have a place in my playback system and you have to respect the product and the audio design and engineering that went into it and still makes it a competitive offering. Currently I use it on my Audiocraft 4400 with a heavy AS tonearm - but it will be going for a Soundsmith re-tip shortly.
Too many people use the cartridge outside of the operating parameters it is designed for and hence many opinions on its performance and capability are inaccurate (but not on this thread).
