I did post something about my woes on the aftersales of 5th ave, Avesco and their repair outlet Super on the Mordaunt thread in the speaker's section last year. Obviously, my posts failed to forestall similarl sad stories. I can only commiserate with your plight. It's really tragic because the MS is such a good performer when it's working. But it's not perfect, nothing is. And when it conks out, the local distributor isn't much help.
Now that my units are out of warranty, I had the same problem asking them for a quotation on a replacement driver on the MS914. It's bad enough they don't carry spare parts for the MS brand they carry, but it takes them forever to even get a quotation for such parts. It's so easy for them to just call up their principal in England or China and get a quotation if they really care about aftersales. But their email problem is not new. I've heard the same response before. I just hope customers of their Gale, Jamo, Teac , Marantz and Kenwood brands have better experience.
