Funny, right on the front page of the brochure it says Digital Processing/Tuner/Preamp = ... sure sounds like a Pre/Pro to me ... or maybe its a Pro/Pre
my Integra DTC 9.8 is much the same - a Preamp/Processor with Tuner - hook up to external amps ... (paid $800 for it used 2 years back)
I kinda think most anyone in the industry would agree thats what a Pre/Pro is ...
What is an AVR without main amps? - why - its a Pre/Pro!
