@grislybutter -- "But is that "normal"?"
I’ve always liked the saying that "normal" is a setting on your clothes dryer.
I think the key is that there aren’t any standardized requirements regarding advertising other than one cannot make willful misrepresentations or fraudulent/deceptive statements about the product. There is no rule against being obscure about a product’s price in your advertising.
So, it boils down to a manufacturer’s or retailer’s best guess as to how to approach their target market. For some that is being upfront about a low price. For others, its "OK, we’re not the cheapest but look what you get for your money!" Or, "Look, we are so fantastic and exclusive that if you’re worried about the price then you can’t afford it." The list of possibilities and variations is endless.
One of the common keys for high-end audio products is they are just that -- high-end. Looks, features, exclusivity, name recognition and bragging rights are the main points of their advertising in contrast to Best Buy’s newspaper ad for what mass market item is on sale this week. So its no surprise to me that the high-end makers are often vague about pricing.
