Balanced v unbalanced input to Ayre preamps

I've been using unbalanced connection between an Oppo 205 and Ayre K-5xeMP preamp, but wonder if the sound with balanced might be superior.  According to Oppo Tech the sound with the balanced or unbalanced outputs from the 205 should be identical, presumably at reasonable cable lengths.  But is the same true with Ayre preamp inputs?  

I'm hoping to replace the K-5 with a KX-5 Twenty to match my VX-5 Twenty amp; the KX-5 has more balanced inputs.  An Ayre C-5xeMP and Sony HAP-1ES use the two balanced inputs of the K-5.

Bob,
The surgery was successful, and I have not experienced any pain since.  The worst part was the 3-week taper off the opiates.

ciamara,
The Oppo 205 is claimed to be fully, i.e., dual differential, balanced.  I may use a passive switch for sharing a balanced input between the Sony HAP and the 205 until I get a KX-5 Twenty that has additional balanced inputs.

IIRC, when I was a grad student working in a psychoacoustics lab during the 60s, 600Ω was the standard.  And then came the DEC PDP-11 lab computer.
