I only heard an Devialet setup in a showroom.... just because it’s so expensive, always worth a learning experience.
Not that impressed, truly.
And I always feel confused when someone said: Hack, you didn’t get good sound because you don’t use that $$$$$ cables.
Look, an Ferrari is an Ferrari. Don’t care where you live, but you still need to feed it with Exxon or BP or Sunoco, the same gas any cheap car would use. An Ferrari doesn’t need ’racing circuit’ gas to be awesome.
So are high-end expensive audio equipment like Devialet. You may not *optimize* their potential with basic cables and power outlets, but they shall never sound average.
