I have the ART PRO MPA and thought about buying the Pro VLA to go with it. (you pay for the 2 rack space look of it!)..it sounded fine but not worth the price tag, or no where near the transparacy of the RNC. (after all you dont want to hear a compresser most of the time anyway)..i bought the RNC and then another, then the RNP, and never looked back! for the $349.00 price of the ART you can get two RNC's...who cares what they look like, rack em in this or look for an old mono dbx 160x (industry standard?)..for around $150.00 good luck
