To be boring about finance, Swiss prices have always been high, but much higher since their Central Bank gave up the fight and abandoned the fix to the Euro, last year I believe. The Swiss Franc has shot up since then.
To get back to HiFi, the only amp which could draw me to the dark side of SS, away from tubes, is the Darzeel integrated. I heard it once with Wilson Alexias at a small dealer show and it was one of the best sounds I have ever heard, till I heard the D'Agostino Momentum amps in the same room with Alexias. I actually prefer the cheaper integrated to the Dartzeel Pre/Power combo. So yes Swiss HiFi can be great.
