I'm at the decision point for either picking up a pair of decent small or medium diaphram condensers (probably Gefell M 300) and a preamp like the UA 2-610....or A second NTK large diaphram mic and a good solid state preamp (suggestions?). Or,...Is it conceivable that I can get a good sound out of the NTKs into the 2-610? I've heard cautions about going tube into tube. This would mostly be for acoustic guitar, violin, and vocals, (keys, bass, and drums go in directly) I'd appreciate recommendations as I want to place my order by the end of the week. Thanks.
