Interesting comments about listening with a lower voltage supply. I ran my IGC at +/- 12v volts (SMPS) for nearly a year. Perhaps it is time to revisit that set-up!

I should add for any 'casual' reader that I have very efficient speakers! :thumbsup:

I took a OPA2134, bypassed with Pana FMs close to the chip, added RC snubbers, tuned the RC values to what I like the sound of, added a C from the + rail to the - rail and powered it with my shunt regs.

Hi Mike,

A bit off topic but would you like to share with us RC snubber values you are using for OPA2134. I have it on output of my cd player.

Thanks, Baki

ps: what is the value of C accross the rails you are using?
