I'm currently using the Jubilee on a Graham 1.5T and it sounds fantastic. It's also a better mechanical match for the Graham (11g effective mass) than predicted by the relatively high 16cu compliance. I get a lateral resonance of 10Hz and a vertical resonance of 10-11Hz with the HFNRR test record - about perfect.
I still have very low hours on my Jubilee, but I'm quite enthalled with its performance. It offers top notch soundstaging and imaging precision with a marvelous tonal balance and realism. The midrange is beutifully detailed and rich without ever sounding too warm; great bass depth/punch and detail (though somewhat less midbass 'weight' than my 103R); very refined and smooth treble range with no brightness/emphasis or glare; quite dynamic and alive sounding; super tracking performance that never lets the cartridge sound ruffled.
Though the Jubilee sounds much more extended/detailed/refined in the treble than my 103R, sometimes I feel like it lacks a little 'bite' in the treble - though this may just be its superior tracking and refinement telling it like it is. Bells, chimes, triangles etc do sound very realistic.
I've played a bit with loading and no setting on my Plinius M14 sounds less than good - even wide open at 47K. However, I strongly prefer loading this cartridge right down. I used 47ohms initially, but I'm currently using 22ohms(!). Focus and image placement is much superior at these low settings in my system. BTW, tonal balance doesn't suffer at these low loadings - and is NOT responsible for my treble observations above, ie treble balance and characteristics is similar across a wide range of loadings. In actual fact 47 ohms is not really loading down the Jubilee at all since its DCR=5ohms. Output is slightly reduced at 22ohms however - theory predicts 0.277mV at this load (0.340mV nominal). I'm not sure whether my choice to use lowish damping in the Graham arm has influenced my preference for these lower loadings. My 103R sounded best at 100ohms though, and this seems pretty consistent with most Denon users. My system
