Upgrade my Theta or move on?

Just curious, since the 3002 is only a two channel what is the purpose of 500w? I cannot imagine what kind of speaker load you could be dealing with.

What do you mean by excess amp power to 'control' the speakers. 'Play' I understand. If too little you get no volume for listening. But too much only puts the drivers in jeoprady, and accomplishes absolutely nothing.

At best, a little over the mfgr min recommended range for 'sense of ease' at higher levels. Otherwise it is just money that could be spent on somethig useful.

It is a myth that more power provides 'better' (whatever that is upposed to be) sound. The only 'sound' involved in amplifiers is audible distortion. Where a distortion free amp has no sound, and that is what you want. Otherwise it is just power.

Once the speaker drivers are operating as designed, any additional amplication capability just sits there in the amp only potentially useful if additional drivers are added to utilize the excess.

It is even worse when someone misunderstands that bi-amping is somehow going to improve sound. When it is just a way to add power if too little is available in the one amp for drivers of the system.

The notion may come from 'a little knowledge can be dangerous' of higher end systems that are multi channel and use two, three, or even more amps for the individual channels resulting from an active crossover (?)

Anyway, if it makes you feel better, as the wife may say :-)

I see, if youve got em... just be careful. It is serious over-kill. You probably only need 50wpc, 100 at most if the drivers are grossly inefficient. At 50 that is 350w total, while the 3005 = 2100w (gulp).

My advise is to check out the Surround Sound link at http://www.linkwitzlab.com which is valuable resource for truth in all things audio.

There some interesting papers at the LINKS link as well.
