Non Authorized Martin Logan Dealers

I am in the market for speakers. I had thought of the well reviewed PSB Imaging T3, but I found the female vocals to be veiled. The dealer (authorized) had Martin Logan Impression 11A. I was very impressed. The lack of box, vocals, adjustable bass with DSP and room correction. I am finding them available at 35%  discount by non-authorized dealers. I would like to hear from people about the speakers and the dealers. 
My present speakers are Merlin VSM and I would like more bass extension, but I still love their midrange.
