ADA, Bryston or Classe

Any ADA owners out there? I have a local installer telling me he preferred the new ADA processor and ADA amps over Classe, Bryston. Also on some forum threads I saw the ADA getting some rave comments.

The thing about Classe Delta is I love their looks but that is exactly what worries me! It seems too easy to buy Classe based on looks where for example ADA and Bryston look ugly at best but may well have superior sound attributes!

So anybody did A/B comparisons on those soundwise - preferrably from a custom installation point of view where looks do not matter?

Still looking for some experience from people who have actually compared ADA to Classe and Bryston.

Design and profit margin may be one topic but should not be placed above sound in this comparison!
