Pipes- Good luck and much fun in your endeavors, grabbing new gear is always a rush. Jtinn, to assume one buys ones gear based upon terms such as "reference" or "balanced", for that matter, suggests a very shallow perspective on the hobby. As for power being the only difference in the ARC series, nonsense. The VTM-200 are monoblocks, nearly as powerful as the 300's and if actually listened to, sound different.The 600's are much more powerful, and to my ears just don't sound as good as the 300's, power/control notwithstanding. It's about the music, after all, not the names/terms/amps/ ad infinitum, the cart before the horse. One has to be comfortable with what he/she likes and decides to purchase. I'm thrilled with the incredible aray of high quality gear from which to choose, and applaud the differences in taste in regards to those choices. Rationalizing why someone has chosen differently, in my humble experience, is usually more about dollars than sense.Respectfully.
