[QUOTE="johnc, post: 79055, member: 2084"] I also don't know what the original looked like. I think the one discussed in the following link is probably quite close to the original: [url=http://www.diyaudio.com/forums/pass-labs/30208-d1-i-v-stage-finished-3.html]http://www.diyaudio.com/forums/pass-labs/30208-d1-i-v-stage-finished-3.html[/url] I am planning my first DAC project and one of the main reasons is that I want minimize the amount by which the analog signal gets stuffed around as it makes its way to my ears. From what I have read, the D1 I/V looks like a good choice. A few questions to start with: 1. Why does the D1 I/V have a +-30V supply? Is the output Voltage supposed to be large ie:20V? 2. Is advisable to match the MOSFETs? [/QUOTE]
