Active speakers. What to choose?

Dome midranges are not all equal. ATC and PMC versions use a double spider to avoid rocking. There is a cheap version from Vifa of a 3 inch dome and it is used in the Beolab 5. The Vifa dome is not at all in the same class as what ATC and PMC use (massive magnets short coils in large gap and double spiders)...so I'd advise to double check whose dome midrange is used in the Linn's. (It should be outstanding given the price of these sepakers but probably worth checking first - the Beolab 5's are not cheap either)

The vifa dome also appears to be used in lower end PMC models. The problem is the precision engineering and high cost to build a high quality dome. Most domes that are larger than 2 inch do not work that well and one would be better off with a regular cone (a cone is supported both by the spider and the surround and therefore is better suited to maintaining alignment - domes also break up more easily and therefore require sharper crossover filters than most cones)

I have not heard the ATC dome, but I did own Dynaudio Confidence 5 for years which employed their best 2" midrange dome.

Midrange was incredible, very life like and detail. micro dynamic was superb. what I didn't like was image lack density and focus. could be the speaker box design, could be the flat face of dome midrange. I would image ATC horn like surround would improve both efficiency and image focus, but that's pure speculation.

I have heard lesser midrange domes, they just don't sound as convincing as Dynaudio Esotar midrange dome.

Okay now that I have settled on what speakers to choose - I have chosen the Linn Klimax 350A.

I am facing another problem. So I placed a deposit for them to have the dealer hold it for me till June but I backed out of it in like 24 hrs because I found a much better deal somewhere else. He said okay to the refund initially then he started saying that the other buyer backed out and decided to hold on to my deposit. Well so he claims because previously I asked about the Komris he has on sale and he was like oh someone offered me more than I was offering him and then he offered me the Klimax, and then he decided not to sell the Komris.
Now he says he will only let go of the deposit till he finds a buyer. What are your opinions on this? I was deeply apologetic to him that I changed my mind but he started saying that it's a contractual agreement that I buy from him but he is not holding it against me etc... But thought it is fair to hold on to my deposit. He kinda sound desperate for money though.
PS. He is an official dealer, I checked that up.

Also to add, the cooling off rule states that I get three days to change my mind about the purchase.
Which i think is pretty standard because whenever I places orders for a large purchase, I will have to sign that agreement.
And FYI. I have not signed any contract. He seemed to be regarding this like a house purchase I dunno... Like if I agree to buy it I am tied down.
If he has other items for sale that I need, I would have totally got them from him. Because i feel bad. But.... now I fee like a pushover. It's only $2300 deposit - small price to pay for a lifelong lesson.
I really need your opinions on this. Am I being immoral or ammoral to back out of the deal because I find a way better bargain somewhere else for the exact same thing?
