Bruce, what would be a better choice/timbre match to go with my L/R 5500? 5200HC or 5500HC sonically?

Also, seems there are several versions of the 5200HC standard, reference special edition, performance 5200.2HC differences sonically?

Lastly, my 568.2 does not support RJ45 speaker links, so I'm assuming any DSP speaker choice must support coaxial digital audio links.
