[QUOTE="John Roberts, post: 51635, member: 126"] Re: Uli Behringer of The Music Group Q&A That is an interesting take on the fixed install market. Perhaps you will be more persuasive than others who have tried to get them to forgo their transformer isolated 70/100V speaker lines (such amps have been tried before over the decades). I've found the install market to be very conservative and resist change, but maybe this time will be different. In the past they seemed far more concerned about reliability (i.e. service calls) than energy usage, and in my experience had a "don't fix it if it isn't broke" mentality. One place where amp efficiency matters is in large equipment rooms that need to factor in air conditioner cooling load, but those guys aren't using class A/B now for the larger amps. You may try to argue how reduced operating temperature of efficient amplifier technology should extend MTBF, if you get that far. I repeat if you really want to save the planet and improve total system efficiency, loudspeakers are not very efficient. Perhaps an end run around customer preferences could be pulled off if governments mandate efficiency improvement. === Many companies choose to go all ROHS because it is impractical to make two versions of every product to service different world markets and the cost saving (of non-ROHS) does not justify the extra handling and inventory utilization inefficiency.
