riskymilk posed a good question: Is the Modwright 9.0X a truly balanced device, or does it merely offer XLR inputs? And I might add, does it also offer XLR outputs? If yes, that would be a clue that it is balanced inside. Otherwise, one is just comparing the "sound" of an RCA interface to that of an XLR.
OK, I just went to the Modwright website. Apparently the 9.0X uses transformer coupling of its output, which permits it to drive a downstream linestage in balanced mode. However, it handles the signal from the cartridge in single-ended mode only, it seems. Hence it bears only RCA input jacks, no XLRs.
