I've been looking at a few output stages, namely the Wadia 27ix and have noticed these devices used in several high end players and DACs. Anyone used these before? Do they perform well, or are there good upgrades / drop-in replacements for these out on the market now? Seem to sound good enough, that's for sure.

I saw it stated as "the best" as in cleanest most uncoloured/natural sounding and quietest (,bla) OPamp in several places aswell.
I have no experience with it but you may want to check out prodigy-pro forums for some comments and implementations

I too would be interested in more in depth comments about ina103 output stages

I played with this chip and other similar ones in my TPM design. Typical BB sound, all of 'em. I settled on the INA121 only because it was the most battery-friendly.

If you believe what you read, they seem to use these for balanced to SE conversion. See last two pages of this thread. Hi res pics of a Wadia also.

Here's a link to audiocrafter's guild's R and D on their x-dac. Halfway down they discussed their comparison between the ina103 and jensen transformer.

cool link. I love these in my CD player's output stage, but I'll probably try a few more things out before it's all said and done
