it is a stretch to say they are the best speakers, period.If you're referring to my comments, they were in reference to SP Tech's top-of-the-line speaker, the Revelations. And yes, to my ears, they're the best I've ever heard.
Did I miss an "absolute statement" wherein someone said they're the best ever, period, for everyone?
As for the Quad '57s, here is one person's comparison of his Quads and an 'older' version of Timepieces he owns. The latest SP Tech speakers employ the use of all Mundorf crossover pieces and parts, a significant upgrade from the speakers he and I own.
