I said 'astonishing' and they were! They were very beautiful to look at. They belonged in a museum. Kind of like when the Met costume exhibit features a major designer like Versace or Dior.
Is great sound a guilty pleasure? Then I think everyone on this site is at least in search of such a pleasure. Maybe my Rembrandt analogy is wrong. More like a fabulous meal in a 3 star Michelin restaurant that costs a fortune but is only for 3 hours. But how long does it really last? The length of a happy memory. Like a great live performance or great sound. 3-4 years isn't bad if you can afford it.
