Dear Dcaudio: Along a change on the tonearm maybe could be a good idea to growing-up the TT to MK IV/V status ( I don't if this could be or I'm totally wrong about. ).
About tonearm, I understand that Oracle goes very good with SME 345/IV/V that makes a very good match with your cartridge.
I don't know which TT mat/clamp you own but making some tests on this subject could help you as could help you too a change on the tonearm IC and phono IC cables.
Now, you state that your Sonny sounds better than your analog rig, could you share with us in which sound reproduction areas the Sonny's sound beat it? is this happen with any kind of music and any kind of LP recordings?. I assume that the tonearm/TT/cartridge set-up is right on target as is the cartridge load impedance through the Phono stage, right?
Regards and enjoy the music.
Raul.
