The Musical Surroundings Super Nova would be my first suggestion for multi-phono inputs. After that multiple phono stages get pricey. At the same Musical Surroundings site the Aesthetix Rhea is worth a look at.

Tube phono can be noisy with the gain up and no signal. The degree at which that changes to quiet when the stylist contacts the groove can be the measure of design.
One of the most fabulous phono stages is in the MFA Luminescence preamplifier (all tube version). Incredibly noisy at idle and microphonic to the touch beyond belief. Once in play nothing I've heard (which isn't saying much) even comes close to the organic and stunning dynamics produced. That evolution continues here:

Square rooms may require more sound absorption as opposed to the preferred reflection control. In any event the distance between the speakers should be the same distance to your ears at the listening position as a starting point for square rooms. Refer to the speaker manufacture as to the amount of toe in as a starting point.
