so i'm browsing around the site, and reading about using transformers to convert an unbalanced signal to balanced

http://www.diyaudio.com/forums/showthread.php?s=&threadid=114093&highlight=balanced

and i got to wondering . . . if you used some 1:1 matching transfomers (such as these:
http://www.edcorusa.com/products/transformers/wsm/wsm10k-150.html which were mentioned in the above-mentioned thread) after a high-impedance pot, wouldn't this essentially confer the benefits (high input and low output impedance) of using a TVC at a lower level of cost and complexity?(depending, of course, on the sound quality of said transformer and pot)
it seems so elegantly simple (and inexpensive) that i feel i must be missing something here. but at least technically, this seems like a pretty viable solution.
thoughts?
 
perhaps this isn't the best forum to post this under. but there doesn't really seem to be an alltogether appropriate place for this, and i figured since "chip amps" is the place to go for simple buffer schemata, and low part count is always appreciated over here, what the hell? anyhow: bump.
