I am wondering if anyone has discovered mechanical faults with the evs inline jobs? The repeated mechanical disturbances from volume control, seem to translate right to the center pin of the RCA jack.
Back to the OP: I am also interested in finding blank/clam-shell XLR's for my own purposes...anyone know of a source...and I have also been curious about the effect on sound quality. It's interesting that one has reported an increase in "warmth", i guess this means maybe the noise floor may raise, or in this particular implementation that this user reports, there may be an interaction with input capacitance such that the higher frequencies are slightly attenuated...although warmth for some means the presence region (~1kHz-3kHz) is attenutated, and dull highs for another means the upper treble region is attenuated (w.r.t. rest of spectrum).
go figure.
