maski ipaskel mo sa pader ang manual, tech specs, lab reports, reviews etc., pag di nagtugma sa panlasa mo ang napapakinggan, useless kesehodang "exact science" pa yan
The amplifier is almost an exact science as depicted by its THD measurement (less than 1% at rated power). Here, you can be dead sure, what you see in the specs (in decent gears) is what you will get (hear in an ideal speaker, if there is one).
The speaker remains one of the most difficult to tame in the electronic chain, despite development in science. Add to this is the interaction it will make with the listening room. Contrary to amplifiers, here, the specs will not give you an idea what the final sonic quality would be - thus, you have to listen very carefully for an issue. And different genre of sound has its own unique issue. Thus it is up to you to draw your selection criteria:
(1) leaning to musical materials and what kind of genre
(2) leaning to HT
(3) striking the middle ground (knowing & tolerating compromises)
(4) break out from your limitations and employ tools to vary amplifier characteristics according to your mood of listening
(this is digital age)
Some considers the speaker as the most critical choice that you have to make - then placing it the right way in your sonically mysterious room comes second. The amplifier will only be selected based on the loudness you want your speaker to deliver the goods - thus your wattage issue. It is almost unproductive to compare SQ of amplifiers with less than 1% THD. You dont compare amplifiers as most pdvd members do it - comparing -20db loudness of 1 to another, and making conclusion that louder is better (sensitivity specs of amplifiers are different, and has nothing to do with SQ)
All of the above are science (exact science if you may) - but in physical world, applying science concept derived from controlled (ideal) environments are not always possible (or maybe dont come easily as just plug n play aka PC), thus limitations/issues abounds. However, this does not mean that voodoo from thin air suddenly becomes applicable and solve your sonic problems!
P.S. Speaker specs, specifically frequency response, if truthfully graphed can give you an idea of the sonic characteristics - but timbre, organics, etc etc (different taste) is so vast a subjective issue to be measured. Some speakers (many high ends) give good response but so wild an impedance dip that no amplifier will ever survive driving it to make a decent sound.
