Quick and dirty op amp shootout

[bobschwenkler]

I tested op amps in pairs against each other just to get a quick idea for the sound. Within each test I unplugged the mic cable from one preamp and into the other while trying not to move my mouth relative to the mic. At some point I'll build a passive splitting network and compare them that way, but for now this is it.

I know it's not at all scientific but I was doing it for myself and figured there'd be some people here interested in hearing.

They were all powered at 17V.

SM7 at close distance from my mouth (under 6") into SCA A12 into Rosetta 800. JH990C, Avedis 1122, and DIY Fabio 2520, Fabio 1731, Ptownkid 990.

The high register on the JH990 was impeccable, and don't get me started on the tightness of the low end!
