@amir_asr "Some of you know that I am the founder of a company (Madrona Digital) that does custom integration of electronics into very high end homes."
I don't know your work (why don't you tell us about these custom high end installations)?
When I was a commercial real estate appraiser, I had occasion to appraise some quite fancy homes in the late-1980s ranging in $5 to $10 million in value. I remember one Malibu Riviera home of $10 million that had Martin Logan electrostats mounted in the walls facing each other 2 stories high. Wow, that must have sounded great (terrible in fact). I saw rich homeowners hiring video and audio installers with $250,000+ systems that were terrible sounding (good video though). I take no credence in your company's installations unless 1. I know what components were used and 2. (unlikely to happen) I can hear the results for myself.
