Analyzing Balanced versus Unbalanced Amplifiers--Difference in sonic quality?

I recently purchased a new Technics SU-G700 integrated amp to drive a pair of Focal 826's or B & W 603 S2 Anniversaries. The amp produces 70 wpc at 8 ohms and 140 wpc at 4 ohms. As a digital amplifier with gobs of technology in it and having a couple of Class A/B amps (Mcintosh MA5300 and MA 162), I wanted to see what the new Technics high-end products touting new technology were all about. What Technics did here was create an LAPC circuit that tests and monitors speaker output via a computer chip versus balanced sound. According to Audio Advice, this circuit does more for the sound than a balanced presentation.
I find this unit to be quiet fast and clear on all phases of the music stage. I'd like to hear from the FOrum members in reference to this (esoteric) rarely discussed topics.
