which is better? a single 6x16 multiswitch or three 6x8 multiswtiches? (both solution provide 16 outputs) when the installer came to my house, he only had one 6x16 multiswitch which turned out to be defective.(two dead ports) His solution was to take three 6x8 multiswitches and cascade them. It works, but the result is a bit mess or cables that resemble a large spider crab in my basement. He said I can call DirecTV and get a 6x16 switch... should I even bother? Thanks!
