By "gain control", do you mean a volume control, or the ability to adjust the set gain (and loading) via dip switches, resisters or even a remote control?
If the later, the ASR Basis Exclusive is a world class phono preamp, (read all the glowing reviews in Stereophile, Absolute Sounds, etc.). It allows you adjust the set gain (and loading) via DIP switches. This preamp works great for very low output MC cartrdidges (my friend uses a 0.2mv output cartridge), or MM cartridges. One reason it works great, and is so quiet, is that it is battery powered, (and it automatically recharges the batteries when not in use). Used they run for just under $4K. (And as a bonus feature, there are actually two phono preamps in the unit, so you can run two tonearms.)
My two cents worth anyway.
Good Luck in your search.
