Thanks Matthias, that was quick...I agree with 45 to 47K and EMI precautions, but 150pF input capacitance are too high for many japanese carts.
...I had to tune my T+A preamp plus phono module by removing all RFI caps resulting in 45pF plus cable 50pF (mech. modified RG180 > lowest cap. shielded avail.) plus tonearm 15pF for a Nagaoka MP500, requiring as low as possible capacitance to cater for ~800mH of inductance to preserve high frequency response...
That´s why I wrote <100pF above...a valid question from my perspective would be to include a (removable) phono cable on a dedicated phono input to meet the EMI measurements at RME, 50p are easy to achieve and more can be added externally!?
Anyway, my main point was to show that all the benefits from high quality digital sound processing could become available for digital AND ANALOG sources in one unit when listening to a live (local) source. Which is of course a personal preference, i.e. operating a turntable for listening.
This would be the highlight for me...(btw. me being a grateful RME ADI-2 fs customer)
In this case - given we have a good EQ system in the setup.... - getting the C loading just right will be far less critical - you can adjust for it in the EQ.
In a perfect world, get the loading right and THEN EQ - but this setup makes life a lot easier!
