Still, are you sure there isn't a piece out there where you would be paying more for the features you actually need?
Looking hard for 2 years; it ain't out there (except way beyond my budget, Manley line level version of the 16x2, etc...)
The old Pultec SP-3 would be great, but how many of those are you gonna find. And Summit made a 4x2 line mixer with their weird tube/SS hybrid technology, but I think they sold about 3 worldwide. THere is a lot of cheap stuff, like the Rane SM26b, but I hate paying for anything that I'm not gonna be thrilled to own 10 years from now.
I did come across a VERY early Manley catalog with no less than 4 different line level mixers, none of which were ever real production models, but they could be custom ordered. But now their entry fee is beyond my reach......
