New jobs opportunities may arrive from old job acquaintances, but don't necessarily signify loyalties to old bosses preferences.
Bryston was often used with older Thiel's, but the later versions like the OP CS 2.4's with their sub 4 Ohm impedances became more difficult for many Brystons to deal with. Very few amp manufactures complete lines can handle such loads comfortably.
