It's funny you mention tube amplifiers. My interest was sparked after listening to two tube power amplifiers from Audio Note (P1SE and P2), which sounded beautifully, so I considered taking that path.
Then I found out that it takes the doubling of watts to achieve an increase of 3db (if I understand the mechanisms correctly).
I downloaded a measurement app yesterday (Spectrum for iPhone). My normal listening level is around 55db measured 1 meter from the speakers on axis - with peaks up to 92db.
I'm not sure it measures correctly / is correctly calibrated. Will look more into this in the following days.
