MC7100 - XLR vs. No XLR?

Hey guys, simple question. I've seen two variations of this amp, a later model with balanced XLR inputs and an earlier model without them. Just wondering if one is worth pursuing over the other, and if there are any other differences between them.

Thanks!
 
The only difference would be if your pre-amp has XLR outputs. If the preamp only has unbalanced outputs (i.e., RCA jacks), then the XLR will do no good.
Also - I believe the MC7100 was not initially designed as a fully balanced unit internally. You will not get the full benefit of XLR unless both pre-amp and power amp are designed as fully balanced internally.
Having said that - if you have a long run from the pre-amp to the power amp, the RCA connections may be prone to hum & noise. The XLR (balanced) connections should clear that problem up.
