Soundhappy, I'm currently driving SE common drain SIT with opamp. It sounds good, but not enough voltage swing, I like the LED thing, I'll try it. 🙂

Thank you for the input.

Good luck finding the parts whose Vgs matches the six Leds.

Personally I think I would use a TL431 and have it adjustable.
