@Pinkus -- is your reference (pun) to the Ref 180 a tongue in cheek quip, or is there a Ref 180 prototype out there? If true, I can't wait for it to come out for all the reasons Taters says.
Pinkus is touting the much believed (but I believe undeserved) criticsm of Audio Research of churning product much quicker than the competition and that the company is marketing driven rather than customer-driven. If one analyzes objectively the product cycles at ARC, you will see new product intros in 3-5 year cycles (with an average of 4 years in between models). I do not think this is much different than most of the competition. Furthermore, having been an ARC owner now for some 7 years or so, I believe that each move up within the product line and from an older model to a newer model has yielded performance improvements consistent with the price differentials. But there will always be haters and that's fine, just not very useful in terms of their contributions to threads such as this where folks are trying to make informed purchase decisions.
