I would not say that, i'm putting an amp/dsp rig for a stereo system for a very big room (still private living room, but for a rich guy) and the amp rig alone is more than a few grants, with no snake oil involved. As his room is big, and he wants a wide dispertion (so when he has a living room party everybody hears the music right) we need to move to movie theater speakers and the power they need is huge. Especially the subs need a lot of power. That's why we need pro audio amps to have enough power and good ones (Lab Gruppen or Powersoft, we still discussing) cost a lot. As they standard have noisy fans, we will have to mod them also (what also costs money). We need at least 3kW RMS power for each sub (there are 4 of them) and 2 x 800W & 85w for the main speakers. The space is 12x20x5m and is semi-treated in the sense that the inner walls are 30cm thick loam plaster that has very good acoustic specs next to very good heath insulation and humidity regulation specs. Floor and ceiling are solid wood with behind thick isolation. The total rig will be arround 40K€ we guess at the moment, which is still cheaper than some cables some use .A decent amp costs anywhere from $100-1500 depending on what you need it to do.
I guess for bigger home theater setups, it will be similar. There is a lot of very high quality that can be had cheap today (which is great), but not everything can be done cheap. Especially if you want a lot of headroom for uncompromised result (no distorted transients) like we do here.
