Any thoughts on Line Conditioners? Any, or Specifically, Rotel's for about $550 ?

What's more important to the overall sound Speaker Wire or Interconnects?

I currently use AudioQuest CV-4 speaker wire, and am considering an upgrade to their Gibralter series. Thoughts?

These are all expensive tweaks that provide arguably little or no sonic difference. Unless you have a very high-end system and your room is already well-treated and more important things are addressed, I think you'll find that many will recommend you just buy quality cables, basic copper stranded speaker wire of sufficient gauge for the length of run, and call it a day. There are many other things that are vastly more important. Such as buyind music.

Adman, Chris is right. Spend your money on things that make the biggest difference first.

Line conditioners, while sometimes helpful, are often times a product looking for a problem to fix.

You know what, I am going to go ahead a disagree...uummm riiiight.... HAHAHA! Anyway, and seriously, I do disagree with everyone. I believe in the fact that good insulated high gauge wire makes a good clean sound. I think that what you have is good enough but I would upgrade if I had the money. I think that both interconnects and speaker wire are important, and if I were you I would spend more money on interconnects not speaker wire, because you already have pretty good wire. I use audioquest too, and I upgraded interconnects in the front and noticed a difference. I upgraded speaker wire and noticed a difference in the clarity and depth of sound. If you can change the room environment to have better accoustics then go for that, but if you have a home theater in a living room like I do then you may have a wife who doesnt like bass traps, so you have to do what you can. I think you will find 100 people that say interconnect/speaker wire is noticably different, and 100 people who say they cant tell. it's kind of like the coke and pepsi debate, I mean you know how it is. But I believe in good cables, not radioshack cheapies. So there you have my two cents.

I run 2 Martin Logan Mosaic speakers - the ones made here in the US when they first came out. Very clean sounding. Paired with a 200 watt Rotel amp, pre-amp, and their CD/ DVD player.

I use AudioQuest Interconnects, but didn't upgrade those. CV-4's are probably good enough.

I can say, the depth issue is true. I also noticed a difference in the clarity from the line conditioner. All of this when you get to a certain level is probably very subtle.

My next purchase is to change my amp to a 300 watt two channel Bryston. Then I'll change the interconnects.
