It looks like your iFi preamp is set to MC, it should be set to MM, so if it's exceedingly loud, that's why. Can you describe this hum/buzz more? Is it a consistent tone and volume? Could be a ground loop issue. Try moving speakers, turntable, preamp to other outlets. Get an inline RCA ground loop isolator if you can't solve it, but it sounds like a ground loop. Put this between your preamp and powered speakers. Does the him/buzz come and go? Does it change when you touch the tonearm? Could be a bad ground, either in the ground wire or solder points in the turntable.
