Even 10dB difference is ALOT more. In my opinion, either you seriously need to see a hearing specialist or you have some super inefficient speakers.
It is always a little tricky doing these "what level do you listen at" comparisons. AFAIK
the efficiency of the speakers is actually not relevent if we are all talking about 09 and newer Denon AVR's with Audyssey MultEQ, as autosetup establishes "0" on the Vol dial as 75dB at the MLP for the internal testtones.
What would chage the SPL (and hence perceived loudness) for a given setting on the Vol knob is where you are seated (closer or further from the speakers in regards to MLP) and the level of your source
. Also, if you have changed the channel trims or changed the source level in INPUT SETUP part of the menu that would also matter. I am unclear if reference level offset matters in this regard.
We have had this discussion about 4 Ohm speakers on several of the Denon threads. This is a matter where the efficiency of the speakers does
come into play. The distance of the listener from the speakers is also crucial, as is the size of the room. Also, a powered sub takes a huge load off the AVR so is highly recommended. So if twin2 is going to use a 1610, which is not designed for a 4 Ohm load, he should take all those factors into account before purchasing. The automatic protection circuit will kick in to prevent amp damage but would also interupt one's listening pleasure.
Twin2's speakers' 89 dB sensitivity is about average. So, assuming an average size living room, a powered sub, and speakers set up reasonably close (<12'), then reasonably loud levels should be safely sustainable, as jd has indicated. IMO "reasonable" does not mean blasting nightclub levels, but rather similar to what you would enjoy in a movie theater. One more point is that SPL is objective, but loudness is subjective. Many people like to "turn it up" because that's when the music "comes alive" on many older systems. Because of the "equal loudness curves" the lower bass and higher treble sound weak at lower volumes. This is what makes DynEQ so valuable, is that it tweaks the EQ perfectly. I can truly enjoy wonderfully EQ'd, balanced, great SQ at a good 15 to 20dB below where I used to, for 95% of my listening. And as Splicer mentioned, 10dB higher is a significant difference, as it doubles perceived volume and uses about 10X the amp power (watts) output. See here
Splicer, your comments about keeping to "reasonable" listening levels to prevent hi freq hearing loss are also quite apropo. Folks should be aware that although the brain accomodates to loud sounds (so after awhile it doesn't seem
so loud, until you turn it off and someone tries to talk to you), the middle ear's ability to dampen loud sounds is limited and cochlear damage will occur based on level and length of exposure.
