I've went both ways on this and find that there is synergy using one manufacture. While it is hard to imagine that every type of cable that a company makes ie,. analog, digital, power will be as good when you think about it if you like there interconnect cables and they sound good with your equipment then you would / could expect that thier speaker cables will sound good also. Not to be confused with whether there are other brands that will sound better. I have been caution not to mix metalurgy, meaning copper with silver because of the different properties effecting the transfer rate which I believe is just resistance. In any event you have to listen to different cables in your system and if they provide the sound that you want then why worry about it IMHO.
Ps: I use to mix silver interconnects with copper speaker cables which my dealer advised against. So I went to all silver and I honestly think that the silver / copper setup provided a fuller sound in my system. lesson learned trust your ears not what you hear or read.
