I'm sure this has been covered if not beat to death, I'm trying to research the best sound quality available in a small or simple mixing board. Something capable of controlling two or more amps and mixing vinyl and or CDs. All too many of these are and sound like junk with cross channel noise, 60hz hum, cheap pots static slides. Do any of them not suck? Or at least suck less. More interested in sound quality than beat mixing features. Any suggestions?
