Sound issues


Here is my current set up. Marantz AV7701, Mac MC205, Oppo 103, PS3, SF Liuto towers, SF Liuto Smart center, SF Toys Monitors (on order), Audioquest GBC speaker wires. The bass is there, but the center seems to be over powered by the towers and missing the highs and mids from the towers. In fact it sounds worse than the set up at the store running a Arcam AV. I have a old Monster surge protector, could that be it? Is it the speaker cables? I'm just at a lost, opinions, thoughts?

Yes, in part, it is the Monster surge protector. Those products will 'steal' current from your power amp(s).

Take it out of your system and you will hear the difference!
leave them playing for a week first(may turn off when going to bed or leave them on quiet)
that's the only problem i see.
other than that i'd take a look onto your mac vu meters and the best way is to have a test dvd-audio source to ensure that the power is distributed evenly and properly onto each group of speakers.
also you can take a loaner integrated amp to check out your mains.
