For Rob,
Are the dynamic current reserves from the supercaps employed in low gain mode with easy to drive loads should the need arise or is that just for the high gain setting and power hungry type headphones? many thanks mk.
It's not just the current reserves that the supercaps are useful, but in terms of isolating the active electronics from the mains power, as the supercap 30F and large inductor means the external PSU only supplies DC current - there is no AC component drawn. This with the RF filtering ensures the PSU is isolated and I strongly suspect this is a benefit too, as the audio related current is heavily distorted, and is a potential source of distortion through the amps power supply rejection ratio (PSRR).
