Ok ta, I've downloaded it ready but not installed yet. I'll see how it sounds with the Duet receiver feeding modded Buffalo dac

Next thing I want to try is the Pass D1 I/V stage

Thanks Chris yes the Ezdac is on the right, I've replaced two of the tants for the dac chips Vcom L/R pins for 47uf 6.3 BG NX Hi-Q's so giving it a good run in. The thing on the left is the Burson buffer. I now want a nice 3.3v reg, a flea may not have enough current so I'm having a browse...

Hi Bud, Sorry I'm late getting back, I've been having problems getting on head-fi, its been running slow and I've had problems trying to log in, its just been timing out! Anyway glad to be of help let us know how you get on and if you run into problems just stick a post on your thread...

Quote: Originally Posted by budx3385 OK. There are two really tiny caps (can't read them) that shunt pins 4 and 7 to ground on both opamps, and then there's a semi-large 220 uF BG near each, but I can't tell if it's in series with pin 6 w/o seeing the backside. THe original opamps were...
