Can I expect to pay full retail for a new system?

In six months I plan to make some major purchases of new equipment that are each in the $10k range or above. Do dealers discount this kind of stuff? I want to do my homework before I venture into a store.

Krell, Audio Research, Magepan ect., When these mfgs show a retail price of say, $10k, is that what the dealer will stick to? On a $10k listed product, is there an unwritten window of say, $1k that the dealer will reduce his price to? Do dealers generally lower their prices for a sale?

I purchased an Audio Research PH5 a year ago at full price, and at the time, it never occurred to me attempt to negotiate a lower price.

Does audio etiquette allow for initiating a discussion of a lower price with the dealer....or is this uncool.

Your comments will be appreciated...thanks.......mitch
