i owned the mbhos for a couple of years, and you can't beat those mics with a sound devices mp-2
I swear, some of your shows that were on STG are what swayed my choice to go with the 603's as opposed to 480's, which were the only other mics for "ambient" taping that I was considering.
I still haven't run these 'Ho's with anything but an AD20 and I am definitely noticing the thin-ness of it, and I most assuredly needed attenuators to keep levels from blowing through the roof!
I would love to try out an SBM-1 with these, as I have never run one before and I have opportunnities to run both my NAK's and MBHO's on the same stand, at the same venue on the same night with another D8 just for the sake of comparison.
And for what it's worth, I have only run my 603's in one venue, for several different types of bands and I still don't get the "brightness" that people speak of.Running them NOS, ORTF, A/B... the only time I have noticed anything evenly remotely "bright" was due to the onstage and PA sound. The biggest thing I have noticed was the lovely way they grab the low end tones and mid's, and the really high ends (like my buddies cymbals) come through much more smooth, as opposed to the distinct tonal difference that I had with the Nak's.
I'm actually considering scrapping the AD20 for a night and just running the 603's line in, just so I can get a better feel and taste of their sound, but from what I have heard in the past I really think an MP-2 is what I am going to search out.
