Just another question, how do you change the opamps? Does it involve advance stuff like soldering or is it just more like changing RAM on a PC motherboard plug n' play?

Nope, sorry. The RCA's are DAC output only. There is no by-pass. So this makes the Zero a "digital only" on inputs, which fits the majority of user's needs. Have a good one!

snip
The Opamps are in sockets, so you pull one out, push one in. Very easy.

Actually, I'm not sure which "term" is used, because some of them have a pretty high output. I'm going to guess pre-amp process. Can someone correct me, if needed?

Oh forgot to ask how many opamp slots are there? Just two right? Otherwise the amount of combinations would explode exponentially, that wouldn't be nice =/

There is one Opamp for the DAC section. There are two Opamps in the Headphone board, L&R. We discovered some time ago that changing the DAC Opamp will change the sound of the DAC output and the headphone output.
If you change Opamps only in the headphone board, it will change only the output at the headphone jack.

So, when I was trying different combinations, I was indeed trying different combinations. That chart represents the better part of a long day! But, I think it will help some folks.

Ok. But since your chart shows combinations of two opamps at once, one DAC one Amp, you must have held one constant on the headphone board if it had two slots?
