U done a vref bypass yet?

Hey Nige, I opted for the BC550/560 mod on the vref opamps. Not going to try the Lifepos there, too skittish. But I am trying to decide if its worth removing the +/-5 regs.

Currently running +/-9v from a two stage PS:TPS47whatsit reg-->Lt3045s-->Dam. I can modify it to supply the dual 5v to the reg pins if it's worth doing. What do you guys think?

Here's a current pic of the build:

Hi i have readed on google, dont know where.. that it is pasible to change clock on dam 1021, that i can put it one freg clock ,this is better then programable. But what with dsd music? I have lots of music in 44khz but im upsampling to 352800. Thank you!

Hello everyone. Have any one experienced i2s lock brake on dam after 1.2v mode? Mine plays for 8sec and looses lock for 5sec and plays again for 8sec and so on. I have full battery power suply mode and it was wirking with no problems. Only started to have signal lock problems after removing 1.2v regulator ot the board an supling 1.2v from external ps.
