what to address first

If you haven't done so already, I'd first install dedicated circuits/lines for the amp, another for all digital, another for your analog (preamp, turntable), and yet another for your sub.

Next, I'd seek out the best dedicated line conditioners and install them. Until you do the above, you'll never know the true capabilities of your components and system.

I would then recommend auditioning the Nuforce Ref 9 Special Edition amps. Then the cables and ics.

-IMO
p.s. I own the 10Ts and I'm a Nuforce and Foundation Research dealer.

Hey Ken, why are you upgrading?? Your setup is pretty great. Give us some help as to what you don't like or do you just have the bug?

Ken,

You have very nice equipment as is. I would stick with the Arials, unless you want to swap out all your speakers for a different brand. You could go to a 6 or 7 channel system if you have the room for it.

In general home theater sound distribution is:

50% center channel
40% L/R channels
10% Surround

You might get more improvment/$$$ in your system by working with acoustics at this point.

I agree with the power conditioning suggestion. You can improve the audio and video with this as well.

thank you all. i neglected to say that i do indeed have individual dedicated outlets and an Exact Power conditioner. I just feel the audio of my home theatre isn't quite there yet. To be honest, I do have a little of the bug.I have been wanting the 20T's but there seem to be better speakers for home theatre.What should I do???
