Friday nights are best enjoyed @ 100 dB

To get an idea you need to know what the efficiency of your loudspeakers is and the power output of your amplifier.

Say you have a bookshelf system with an efficiency of 91 dB (1W/1M) typical. If you listen with an average amp output of 1W your level is 91dB (per channel) 1 meter away. If you're listening at 45 watts (average would be rather high) but to figure this out just take 45 and press the log key on your calculator. The result is 1.7 rounded. Multiply by ten since the d in dB is deci or 10x. That gives a result of 17dBW. Add 17+91 (the efficiency of your loudspeaker) and you have 108dB. That's pretty loud and for an average level - unreasonable with most music. (Of course the way they compress pop music it's very possible given the mashed crest factors but that is another discussion altogether. )

The newest addition is at the top of the rack - Music Hall MMF 2.1 turntable, underneath that is the receiver (HK AVR 335) followed by the rest of the heavenly stuff, Paradigm Studio 60's and an SVS PC+ subwoofer.

Sorry for the blurry pic though, camera doesn't have a very good lens... basic P&S camera.

Don't you mean 100 dBA?

What weighing scheme are you using? A, B, or C? ;-)

Don't forget that "hi-fi" systems suffer from quite a bit of power compression.
