yioryos, your exclamation point made me wonder if you find some lack of credibility to beavis' assertion that he listens at @85db. i do not know why beavis mentioned this but many of us do own meters for kicks and also to conduct objective tests on overpowering amps as well as a myriad of other useful comparative tests. personally i think anyone involved in 'hi end' stereo sound would find it VERY informative to have a SPL meter laying around. they can answer a lot of sonic questions accurately and save a lot of time. just my 2 cents. i keep it next to my remote(s) and refer to it for kicks eg. if i decide to measure a loud passage to find out how loud it 'really' was.
A question I suspect reveals a lot of ignorance...
Does the volume at which I listen affect the rate at which my tubes "age"? I'm thinking more volume requires more voltage and higher output voltage levels represent "wear" on the power tubes. Thanks in advance for your tolerance.
