The real magic exited the company with Serblin's departure (he made a few more models on his own), but it lingered on for while, ever diminishing. I auditioned the Veneres and thought them engineered to impress in a 2-minute hearing, but sub-par for the long haul. Time will tell if the Sonnettos are the start of a come-back.
