I recently connected the 205 to the Ayre K-5xeMP via balanced analog. The sound is now very close to that of the Ayre C-5xeMP, i.e., superb stereo. For this particular pairing, balanced makes a difference despite Oppo's claim that XLR and RCA outputs should sound identical. Ayre emphasizes fully balanced and zero feedback design, so my experience may not generalize to preamps or processors of other manufacturers.
