As an EE, it's definitely about the specs. I own Ayre MX-Rs. First of all because they sound unbelievable paired with my Nagra PLL and WP7s, second because they provide more than ample power reserves (yeah I know that's a spec) and third because they're aesthetically pleasing to look at.
What amps do Electrical Engineers own...why?
Not being an engineer, I would like to know what the electrical engineers in the crowd own for amps and what engineering features made them choose that amp? As a lay person, I don't know enough to be able to differentiate good engineering from good marketing.
