I used to own the Infinity P362, so I have no doubt the EMP sound great.
So the SQ is there.
But I was thinking beyond the SQ; IOW considering factors when SQ are equal. Some people are willing to pay more to have speakers made in USA, England, France, Denmark, etc. Some people are willing to pay more for more prestigious name brands or for better subjective perceived aesthetic or better speaker posts, etc. It is superficial, but human nature nonetheless.
Oh, regarding MSRP, sometimes they are the same as the actual purchased price, not just "suggested".
For example, B&W, KEF, Focal, Dynaudio dealers will tell you that these manufacturers are quite strict about their MSRP - they expect people to pay full MSRP. Dealers are warned of losing their speaker lines if they stray from MSRP.
When I was buying my Focal, I thought about getting the Solo6 Be. But I could not even find a single dealer that was willing to sell for less than MSRP.
When I was buying my KEF 201/2, our Edmond local KEF dealer would not sell below MSRP; he said he would lose the KEF line if KEF ever found out. Same with our local Edmond Revel dealer when I was buying the Salon2. Our local Edmond B&W dealer said the same.
So MSRP is not always "suggested"; they are being expected & demanded of dealers by some manufacturers.
