The New Audio Research Reference 6

I don't think ARC is the only company to benefit from this strategy. After all, when was the last time that you heard a company release of a new product advertisement that went like this: "Our latest preamp is unfortunately a step back from our last design and we really have no clue as to why. The parts are superior in our new model, the designers worked longer on it, the aesthetic is better and yet is sounds worse! However, please be advised that the price is at least 20% higher, because of our needs for increased profits."
Here's the thing, that exact scenario has happened on numerous occasions in this hobby. As some of us can easily attest.

Mitch, that's what's nice about the ever ending upwards curve of new product introductions. There will be some great gear coming on the used market and at far more palatable pricing. I picked up my ARC D70Mk2 for a literal steal after it was placed here on A'gon. The assumption being that over the many years the newer pieces are better than this old classic. However, as several other local a'philes can attest, the old girl still can beat off most newcomers. Why, because like may designers, WZ Johnson had his 'golden' era- and he had periods that were not so great. The trick is to find a piece from your favorite designer that falls into the 'golden' era. Today, I still believe that in WZJ's and ARC's case, there are numerous pieces that followed these amps that simply don't hold a candle to them....including many of the current amps from ARC! When a designer hits one out of the park, like WZJ did with the D70, M100, D115's, then it is SUPER hard to repeat!
