What worries me is down the road , these Hypex and ICE type modules will be no longer available for repairs like in the early Audio Research digital amps.
Yes even now many techs will not try to repair them down to component level, as they are very congested with smd (miniscule) parts, and the pcb's (printed circuit board) itself can be two three or even 4 layer designed which make it impossible to trace a fault.
Many techs I know now, just say throw the whole module out and put a new one in, if it's still available!!, if not the amp becomes junk.
