My DCs have also performed well for nigh on 20 years now, but Triggers Broom springs to mind.
I’m now on my 2nd Bose A-20 (some thieving scroat had ithe first away) and whilst very good as has been stated already it isn’t robust enough for instructing - not just the moulded plugs. It’s been back twice for repair but having said that both times at no cost to me and came back with new “consumables”. Can’t fault the service.
Doesn’t help you make a choice (I think you’d ruled it out anyway) but probably enforces your decision to search for another (cheaper) option.
Remember though - buy cheap, buy twice!
