Sonodore omnis should be placed in between the (rather warm) Schoeps and the (quite clinical) DPA sound.
Not hearing the smoothing you're referring to compared to other preamps. But, my definition of that is likely different and we may be hearing the same thing.
Personally, I believe *most* preamps contribute 5% or less to overall sound within certain limits. Yes, I bought the Forssell for that 5%. After using the preamps in the real world AND performing extensive double blind comparisons, the 2A basically acts like a true upward compressor, pulling up low level details (dB) without touching peaks, although very subtle. You can literally see this when looking at the density (RMS) of the waveforms between the 2A and most any other preamp. This falls in line with others' description of its sound.
For what it's worth, I don't do orchestral recording; I use the 4006As for mid/near field miking with the silver non-trapezoidal grids.
