Nope. Because gain is gain. A pro power amp with 32db of gain is still going to have the same gain as a home hi-fi power amp with 32db of gain. Doesn't matter if XLR or SE is being used to feed it. Feeding a pro amp XLR doesn't not mean the gain will be any different. It just means the input signal will be higher, typically x2 higher than RCA, if from a DAC with both SE and BAL outputs. The only thing I see is that the pro amps pay less attention to THD+N, and their sweet spot is a bit higher up in the power range. Still, much of this (perhaps all) is meaningless, because the CDi1000 with its merely good 70db SINAD measurements (and worse at lower power levels, which I'm sure I'm in with the big efficient JBLs), sounds way better than probably any amp up to $2.5k sold at Audio Advisor.
