Which Resistor for cartridge loading?

[apaulr]

I put in the 100 ohms and I was surprised that I had enough gain. I was able to rotate to the 11-12 o'clock position with a comfortable listening level. Beyond that it started to get real loud...then again my listening space is not large. The noise floor is excellent. I think I can live with that. Thanks for the options.

Wich sensibility have your loudspeakers?

[apaulr]

I am not sure of the sensitivity , nevertheless the speakers are Thiels CS3.5.and I use one of two amps at a time ..Adcom GFA 555 or a MCintosh MC2105...regards

As per Stereophile archive Thiel CS3.5 have 88dB/W/m, MCIntosh 105W 4 ohms, Adcom GFA 555 325W 4 ohms, small listening space can help.

Thank you for the follow up..I appreciate it !

For MM load input Salas moderator suggest to put a 100K trimmer instead the fixed 47K load resistor to trimm by hear best result & after change for a very high quality fixed resistor.

Overall gain at 67dB with your power amps seems to be sufficient. My set up has 30dB gain via SUT, 48dB via phono stage and 4dB via the line stage, my power amp has 20dB of gain - I could loose 10dB and still be fine.. So it seems you have a relatively sensitive amp.. (two actually)

Especially the MC 2105...very sensitive
