re: VTL/ARC
The fact that they may use these as reference speakers (for now) doesn't necessarily mean anything except that:
1. Manufacturers need to know how their stuff will sound with the other popular speakers/equipment of the day.
2. VTL and ARC are marketers, too - how would they "look" to the deep-pocketed Stereophile audience (i.e. their target market) if their references were the more accurate Meadowlark, Dunlavy's, GMA's or Vandersteen 5a's? Those are not Sexy - especially if they're no longer in business.
3. Who says that guys who build amplifiers necessarily have ears any different/better than the general population. There's no doubt that a lot of people like listening to Wilsons, so why shouldn't they. That's not Hardesty's point.
What Hardesty says is irrefutable (and you don't have to be very "smart" or knowledgable to understand it) - The Wilsons are made with inexpensive off-the-shelf parts and are technically modest designs that make it virtually IMPOSSIBLE for them to be true a "reference" (as in REPRODUCE THE SOURCE ACCURATELY) transducer. There is simply no argument to be made against him.
Wilsons are built nicely, finished nicely, and it's not wrong if you absolutely LOVE the "sound" - but it's not what the old school audiophile considers Reference. I love to I crank up my DBX expander, use Impact Restoration and pump up the punchy midbass with an EQ for certain recordings - but I wouldn't claim it's audiophile reference. It's fun as hell to listen to, but I sure wouldn't want my speakers doing it automatically without my permission.
As to these people who harp on whether Hardesty had a pair at home to "review" - You don't have to fly a plane with one only wing missing to know that it's a bad idea. You don't have to drive a Ferrari with 3 wheels to know that a 4-wheeled VW will outcorner it. You don't have to hear a 96k sample rate recording to know that it sounds better than the same session recorded simultaneously at 48k and then downsampled to 44.1k. Speaker design is not as complicated a mystery as high-end marketers would like everyone to believe. Accuracy is predictable and measurable - and to a some degree, obtainable. Coloration is not so predictable - hence the vast choices in what type you can purchase. And yes, expensive coloration DOES sound better than cheap coloration.
It's not lost on anyone in the industry that almost every speaker builder who produces (near) flat frequency response, time and phase coherent designs has gone out of business. "Flat" doesn't sell speakers. Punch and Sizzle does. Even if a Zillion people love Wilsons' sound, that in NO way invalidates any of Hardesty's points.
