The reputation of McIntosh and B&W has extended to many Asian countries such as China, India and Vietnam. There are plenty of buyers who are willing to pay any price to own a McIntosh B&W system. In the future, US buyers will see even more "ridiculous" price increase for these two brand names.
A canon 80mmm f/1.8 costs $370 while a f/1.2L is $2000. People always says the 1.2L is better but not 5 times better. It's not about many times better or how much an L lens should cost. It's about how many people are willing to pay the extra. You consider the McIntosh MC275 a piece of art and try to save dollar by dollar until you have enough money to buy it. It is not the case for many guys in China or India. for them, it just a matter of writing a check!
The manager at a local store was nice enough to set up a multi processor system using 7.1.4 Focal Electra speakers to compare among Integra 80.6, Marantz 8802A, Onkyo PR-SC5530 and McIntosh MX160. It took me virtually no time to figure it out which processor I needed.
Buy what you bank account allows and love what you have. Don't compare because you'll never know the true answer.
