140>248 wasn't right to my ears.
140>148 would be much better.
schoeps are a different best though. they are so thick in the middle, that the 248...which leans towards the transparent / detailed side of things (vs the 148), really works best.
especially w/the cmc6
the original m118 was "voiced" with cmc5, or earlier. which to my ears..are a bit exaggerated around 250Hz and the 148 warms the shit right out of them, yielding such gems as those smokin' 1985 GD shows on archive.
Of course each mic has it's own signature and I'm dealing with generalities. Personally I'll take the 148 over the 248 for most any microphone for recording shows. In fact I don't think I ever recommended the 248 for Schoeps mics in general unless that person told me he had a fondness for the treble knob.
It's fun seeing how other people group gear or place labels on things. What sounds hard, sterile, or overly accurate in my mind can be described as low end rich or warm by others. Many times I find myself responding to a post here only to hit the delete button simply because another opinion only furthers the conversation, not necessarily getting any closer to a truth for another. In reality the best that can be accomplished is that folks begin to find trends with which they can begin to discern how another individual hears things based on his/her classifications combined with personal experience. Then you can decide whether you're in sync with that and attempt to get and idea of how it's going to sound to you based on those ideas.
As far as these two boxes go... the Portico is one of the few new boxes being used in this scene which has really peaked my curiosity, such great detail with a bit of warmth while remaining extremely open, and I'm already big fan of the 148.
