SC25 and Avedis 1122 different enough to own both?

[corn55]

Is there anough tonal difference between these two opamps to warrant using both? If so, how do they sound different?

The 1122 has a higher slew rate and gain - bandwidth product than the SC25 and is a bit more "hi fi". The SC25 is intentionally slow compared to most modern op-amps in order to better mimic an old 2520. The contribution of either op-amp is dominated by transformer distortion, however, so the difference between them when used in the A12 is subtle.

Thanks Tim!
