I don’t think I can give him a negative feedback as I did not buy anything from him.
Look at the cable on the link I put up. Spectral / MIT cable are example
Interconnect cable MI350UL II and other example Speaker cable MH770UL II
What he tried to sell, on the Cable box it says MI770UL II. MI is interconnect and 770 is speaker cable not interconnect.
Have a look on Spectral’s site to see list of cable they make, what he listed is not on Spectral or MIT’s site.
Also if he had an explanation, why did he not reply to my question?
