I am really curious to know how your 'clone' plays. Can you compare it to other projects/commercial phonos? It certainly is very different topologically and i am sure has unique sonic character.

Please tell me about the function of Ri - it's a real resistor, not the internal resistance of your cart, right? Have you tried current mode? It will obviously require to recalculate the first NFb network.

Analog,

Ri is indeed the internal resistance of the cartridge. Recalculation of the feedback loop is necessary as far as the gain is concerned, but for my cartridge (DC 38 Ohms) it does just fine.

Can you tell me where you source the Op-amps from?
