A few comments
1 XLR is not the same as inherently balanced. While XLR means a balanced interconnect far too many achieve it with an extra (meaning more noise, distortion) stage to convert an otherwise unbalanced circuit to balanced. Don't be fooled.
2. If you think ASR specs are the end all, we have little more to discuss. And this is from an EE who's been CTO of some large tech firms. Music is not so simple.....
3. Why is XLR/balanced so important to you? Its real benefit is noise immunity. I seriousyl doubt you have that issue in your home.
