AudioPhile Review mentions Old Blue Sound

“Just like most music lovers I’ve heard more bad sound reinforcement than good, but sometimes the good can come from modest amounts of gear. Old Blue Sound Company, who do the Mid-Winter Bluegrass festival in Northglenn, CO, have year in and year out with many different equipment combinations, delivered more than merely adequate sound for that fest. I usually try to sit close to their board, near the back of the hall, because their sound is nicely balanced and not too loud.”
