Uncle Dave-

So, for the most part, if I'm clearly pleased with my live sound as is...it wouldn't be a significant improvement to look at adding a mic pre-amp, true?

The subject came up in my openign discussions with the sales tech when I was looking for new pa speakers...The tech felt with a mic pre-amp, it might enhance the vocals to where my old yamahas might have been acceptable. Regardless, it wouldn't have addressed any of the instrument sound reproduction...
