New Perlisten S7T Towers

I am one of their dealers.  Read the review in Audioholics where they say this is the best speaker they have measured to date. 
Frequency response is flat and they are very natural sounding but with lots of detail.  The design uses a Kilppel measurement system to optimize output.  There are certainly a lot of great speakers in this price range but these are one of the more impressive options.  

The only thing that might be more impressive than their speakers is the subwoofers.  
Dealers are instructed not to discount.  Best bet is to trade something in against them.  

Second question, what percentage off of full retail would you consider fair?

At this price level the ONLY questions that matter are if they have the sound characteristics that are most important to you personally and if they match well with your existing equipment/room.  Everything else is a rounding error, relatively speaking.  

mijostyn-   Those "checker board" drivers are SB Acoustics woven TeXtreme mid/bass drivers made with an advanced, super thin carbon fiber fabric-

2 ago I noticed that chess-board pattern on some Rockport speakers.  Common supplier?   Likely.  I was looking into Rockport after hearing a good podcast with the founder and the two guys running the business with him now.

I have these loudspeakers, and in my view they are the best I've ever had/heard, as long as you have the right power driving them, Truly magical sound.  I paid full price, and was happy to do so.
