Hello Dart6,
I spoke with Simon because I don;t like what I read. He replied that you have three amplifiers: one you bought from them, indeed, and two used on Audiogon. You are the "brave soul", I would never ever buy used amps from New Zealand.
Moreover, he said that he presented a few options to the business manager (Toni) and "thing" is out of his hand.
Good Luck but if one takes chances with purchase of 2/3 of the equipment used then sometime one has to pay, if not in money, certainly in "efforts". Good Luck!
