Smile My SDS Labs headphone amp

Just to show headphone people my implementation of the SDS Labs HP amplifier.

I use IR mosfets with gate resistors and an adjustable Vbe multiplier for biasing the output stage. Very smooth while remaining precise. Highly enjoyable with SR125 from Grado. I found this simple but honest circuit adequate for beginners.

Thank you Sheldon...
