Using single speed g-ch to supply double speed current(left channel + right channel)?

It's not a bottleneck if the current ratings of each of the channels are far above any practical limit. Don't forget that M³ and β22 have fast, high-current output MOSFETs rated at 17A+, and the σ22/σ11 power supplies are also capable of very high currents... No headphone load will draw anywhere near that much. Typical output currents are in the tens of milliamps. Even the little Mini³ (high performance edition) have very fast opamps capable of ~200mA output.

Sorry, I do not use MSN and don't usually use any IM service.
