my friend is giving me a Sony 5.1 receiver because he is getting a new one. I just wanted to know if 80 watts are good enough/loud for a bedroom because that's where I'm going to be keeping it if I take it.

Yes; 80 watts is generally going to be plenty for most budget speakers. The average 2.1 computer speakers are probably only about 15 watts per channel. If you're looking for speakers, just be sure to look for highly-efficient ones. Efficiency is measured in db at 1w/meter, and is a standard measurement if you ask or look. A rating of below 86 is going to be low, 90 or above is going to be highly efficient. Good luck, Boz

Wattage is not a very useful measurement in comparing one receiver to another, since you can arrive at varying wattages depending on your measurement and testing methods. many manufacturers artificially inflate their numbers using "peak" power, which is not a true indicator of output. Further, without knowing the make and model of your receiver, as well as the speakers that you plan to power with said equipment, it is impossible to say whether either of your receivers will be decent, good, or great at powering your respective speakers. My statement was more general in nature that 80 watts is sufficient to power most speakers at normal volume levels. In fact, normal volume levels - such as normal talking volumes - require very little power. Happy gaming, Boz

80 watts plenty unless you have really expensive speakers. My 90 watt 7.1 receiver does my KEF/B&W 685s perfectly.

It depends on the source as well.

My Denon is 90wpc (with 8ohm speakers, 125wpc with 6ohm) and volume goes from -80db to +18db.

For normal music listening I find -40db plenty loud enough, DVDs seem to be mixed quieter, but still -20db is fine.

80wpc should be fine if paired with half decent speakers.
