7th Circle Mic Preamps?

All the talk of the SCA's A12KA (the many posts I see that say in blind listening tests the SCA A12 sounds better than API 512's) I am wondering if I should try them out. But I'm curious what op-amp was in the A12 you were listening to? That makes a major difference in response, and I wonder if it is the stock component or the API op-amp, or something else.

Anyone who has the SCA A12 and original APIs with the mod (1kOhm resistors strapped on the output) in a lunch box ever compare the two side by side? I'm looking for more information and thoughts.

How about the N72? Do they compare well to original 1272s or Great River preamps?

Thanks for your thoughts.

My A12's have Tim's SC25 Op Amp. On his forum, a user did some graphs comparing it to the API 2520 Op Amp. They were almost identical with the SC25 actually looking a little more favorable.

Mine win shootouts with 512c's almost every time they go up against them. They are quieter too. You won't be disappointed.

If you do a search you'll find Michael Wagener's posts of his SCA - A12 experiences. I've been told he used the version with Tim's SC25 opamp and actually liked it better than his API's on a number of sources, though most of the time it was too close to call.

I own a pair of N72s and J99s, which I love. A12s will be next.
