What do you consider "loud" for your system?

Loud for me is 85db. Normal listening levels for me are around 60db. Not exactly a head banger anymore!  That ship has sailed.

Just to clarify, dynamic range can be looked at in more than one way.

My comments above were directed toward the original post -- the perception of how loud the music seems when listening -- richmos said he is listening at 90 dB with 96 dB peaks, using a classic rock album.

I looked at the song "Money." The Audition statistics showed a 59 dB dynamic range, with periodic peaks 10 dB above the average level. That's pretty good for a rock record (but it is an "old school" recording.) So, you can see that there is nowhere close to 20 dB in peaks above the average listening level.

The other thing good dynamic range can do is let you hear instruments and sounds that are much softer and in the background while the overall volume level is loud. A poor dynamic range will leave these softer sounds buried in the background noise.

richmos. You have it right. I generally listen to rock at 95 dB. Louder does not add much and risks your ears. Always warm up your ears. Never go immediately to full tilt boogey. Start at a lower volume and slowly turn it up over 5 minutes. Give your ears a chance to accommodate.   

@mijostyn...That's the way i usually approach it. Start at around 75-80 db and then get cookin'. It's rock n' roll...right?
