Why would anyone prefer anything besides Audio Research monoblock tube amps, when they are so awesome? For only $70,000, plus a 5 ton A/C unit to cool it, you could begin building a truly great system. All you need, besides the above, is a $10,000-20,000 preamp, a stupidly expensive source or three, and a room to put it in. Then, you could chase away all of your friends by showing them the intracacies of minute passages of music that really show it off. I prefer the Class A Audire Monarch towers, and a Diffet 5, but settle for a trio of Audire Fortes (Plus two Audire Diffet 3 preamps), and really love my music, even when listening to Jazz 67 on XM, despite its inferior sound. Why would anyone prefer a beautiful Ferrari to a Bugatti, when the latter is faster? Why would anyone prefer a wife of fifty years, when a Russian model is cuter?
