Some guy was quicker than you and bought the amp. If you had been quicker, you would be bragging rather than complaining. Somebody had to win and it wasn't you this time. It wasn't me either but I have the good sense, first of all, not to want that stupid amplifier and secondly, not to think I was entitled to it.
Another important point that I haven't seen addressed here is this: He's asking 46% more. Asking. I see no mention that he actually got his price. He bought the thing on speculation and he runs the risk of facing a marketplace that feels as I do about overheated, military-grade, archaic iron. If it's any consolation, I would gladly have stepped aside and let you buy that Krell. I guess that makes me a good guy, huh?
