Buffer question

[DryRoasted]

Hi all,

Just had a thought, if I take the bog standard ruby mini amp circuit and put 9v through it, the buffer presents a nice high impedance signal to the amp and we get sound A.  I fI now put 12V through the circuit, discounting the extra clean headroom from the increased voltage, and any other effect on theamp side, does the increased voltage affect the buffer in any way, either its operation or the resulting signal?

cheers,
Jim
