One of the side issues associated with this topic is that of ticks and pops. If the phono section has good RFI immunity and if it also has good high frequency overload margins, that peak at 1 or 2MHz won't overload the input of the phono and you'll get less ticks and pops.
That is absolutely true. In fact, with a clean LP (the only kind I play), ticks and pops are virtually non-existent. I've played LPs brought by visitors, after cleaning them ultrasonically, and they've been astounded by the silence.
I use an ARC Ref Phono 2SE balanced into a Ref 5SE. With an MC cartridge, the difference between 47K and 100 ohm loading is virtually undetectable and may even be zero. (You can use the Ref Phono remote to change loading from your listening chair.)
For all the ad hominem attacks, handwaving and double-talk that has plagued this thread, I've yet to find any fault with what @atmasphere has explained.
