Question, how does replacement parts availability effect a trade up program? When trading up isn't the customer simply trading in their "old" amp for a new cubed amp? So how does parts availability impact new items in that case, if parts availability was an issue I would think current amp production would have been halted or seriously scaled back and dealers would have been informed so that info could be passed onto customers to either expect significant delays with no ETA on delivery date or the customer would be told Bryston is no loner accepting new order? Or am I misinformed and the trade up was never for new cubed amps but rather against a refurbished cubed amp?
