Sorry, should have posted earlier but just stumbled on this thread.The posts above would certainly cause some misgivings if not real concern for any prospective Quad customer. While I fully understand and appreciate that its pretty harrowing to have expensive audio equipment frequently break down with no real assurance of a remedy from the dealer/manufacturer. I only want to share a quite contrary experience regarding my ESL 2905s which I've owned for nearly 3 years. Have had absolutely no problems running them in a hot and dusty enviroment( New Delhi, India). The only problem I've had is with the rather flimsy speaker binding posts, made from aluminium, you would expect better quality in a $11.5k speaker.Anyway got a prompt replacement in less than a week.
Of course experiences will vary but IMHO the new Quad line are truly outstanding speakers . I have come close to contemplating a replacement but that holographic soundstage and mid range is hard to match, let alone surpass. The 2905s have their weakness, they won't play too loud, LFE is on the weaker side but paired with the right subs and tube amps they are heavenly.
Cheers
