As far as I recall, pcm1794 has twice the output current needed, so you'll have to scale down the gain in order to avoid clipping. But it should be easily done. ;)

Thanks Cviller:) I've been searching around trying to find some info how to use it with a dac that has +/- outputs , if I had a balanced pre etc I'd just build a pair of D1's, balanced in balanced out but I need line out.

I presume theres some instructions in the manual how to connect it up to various dacs?

You won't find much instruction in the manual, but d1 is balanced anyways. You make 4 identical iv stages and use two for each channel. I have single ended preamp, so I just take the signal between + and gnd on the output of the iv stages. A bit of a waste really, but I'm planning on building another preamp to match my F4... :D

Ok thanks, I was hoping to be able to use just a pair of the D1's mainly to keep things compact with the PCM1794 dac, oh well:)

Hi cviller,
Did you build the D1?
