A1126lin: You don't want a 20.0, or a 20.6. You want a pair of 20.5's.
The 23.5 has XLR's and Camac/RCA (the Camacs were replaced with RCA's in the later production runs.) It can also be bridged (400W into 8 ohms)
I'd love to have a pair of bridged 23.5's! (To be honest, I've never heard what a bridged 23.5 sounds like -- maybe it sounds crappy!:~)
Also, unlike some amps with fake "balanced" inputs (eg Rowland, Audio Research, ......) the Levinson gear is fully signal-balanced throughout the chain of components -- from the preamp input > output > amplifier.
