certin speaker makers harder to get dissounts fro

There is another answer to your dilemma: Buy them used.
In looking here on Audiogon, there are dozens of used Martin Logan speakers. If you can't get the entire package here, you might be able to at least get some or most of them used, and then limit the amount you end up spending at a dealers.

Just my two cents worth.

PS When I bought my ML Sequel IIs, many, many years ago, I got about 10-15% discount without trying to much.

I learned a great bargaining tool from a guy who bought a used car from me once. This guy came to me with $100 dollar bills in the amount he was willing to pay for my car. It was considerably less than I wanted to take but couldn't resist the quick sale. I haven't tried this at your price point but it has worked in many situations. Just know what you are willing to pay (it should be reasonable), have funds available, talk to the decision maker and be ready to follow through.
Money talks.

B&W dealer markup is 100%. After telling me this, the dealer offered 5% off.

I have been buying audio equipment since the mid sixties.In those days you did not get any discounts from the very few high end dealers,the seventies minimal discounts however service was impecable you could borrow equipment for home audition,the dealers were knowledgable.They came to your house set it up for you,you did not like the sound they would exchange for full value of your original purchase etc.
well in the ninties minimal or no discount,but NO service,delivery charges set up charges.Set up people had no idea about the equipment they stil charged like experts $60/hr or more.That is when I started using audiogon to purchase equipment.I am willing to pay a fair price for good service.The Audio store that will provide that MAY survive.
I beleive that the future of high end audio retail will be based on direct on more direct purchase from manufactures,direct manufactures show rooms(like in the furniture business design centers) and most important speciallity services for home set ups charging by the job or by the hour.I would hire that expert in the washington DC area in a minute and pay premium.Under this set up everyone will win the maker of equipment that sells for 4X could sell for 1.5x and the user/hobbiest could afford more high end and the qualified specialist could make a good living without the huge investment of starting an audio retail outlet.these are my 2 cents.

Bignerd,im not implying anything & im not mistaken, my figures are a fact,'certain' dealers get additional discounts for being a select/premire dealer of certain brands & they also get another discount for paying their bill to the manufacturer within 30 days & the added discount percentage's are not small,do these additional discount's not apply ?

notice that i wrote "up to 60%" when i was refering to mark up & that reflects on some of the highest priced speaker models on the market,not every model has a mark up in that range but they are there none the less, you are correct that certian manufacturer's have no discount rule's but the problem with that is that not everybody follow's these rule's so where does that leave the consumer ?

all the guy's who preach the death of hifi kill me,hifi isnt going anywhere nor are dealer's, the same guy's tout this big wealth of knowladge that can be gained from dealer's,i'll agree that you can get good advice from any competent dealer but that advice alway's come's at a price.
