How many dbs i will gain with 0,6mv cart.vs 0,3mv?


Hello
I am loading my Shelter 501mkII (0,3 mv output) cartridge into 47K as reccomended by the manufacturer.When switching from my cd player to analog,i am always compensating volume by +10 (CJ Premier 18 LS)to match the same loudness as my cd source.
I was wondering how much i will gain if i switch to 0,6mv output cartridge (Koetsu Black)which has the same reccomended loading as my current Shelter.Thanks for your opinions.

Since your new output voltage is twice your old voltage, the gain is 20 log (V2/V1), which is 20 log (2), which is 6 dB. So you would get an additional 6 dB of gain from switching cartridges. Looking at it another way, you would need 6 fewer dB, or half the voltage gain, to get the same volume output.
