You may have already considered this, but in a totally different price bracket, the Parasound Zphono XRM ($650 USD) has that spec: two inputs with XLR output, inputs are easily switchable at front panel, and two gain options for each input with custom loading for the MC input. Subsonic filter and mono also available on front panel. What more could you ask for the price?
XRM has limited measurements from
Aussie Hi-Fi, but they’re quite good (assuming you don’t use the subsonic filter which is overly aggressive).
I have one and think it’s a solid piece and remarkable value. Dead quiet for a phono stage and provides a strong, clean signal. Would be hard pressed to think I ever need an upgrade for my 1200GR+540ML.
