Exactly the only way to test your sound reproduction accurately is with equipment that samples sound at the same rate it is produced making any missing data between samples undetectable.
True, but MY ears are the final arbiter of the quality of sound reproduction of MY audio systems! Yes we can objectively measure everything, but my SUBJECTIVE experience of the sound counts for the most!
Clean power is all the same. Not all amps will sound the same though. Even from within the same class. This is due to no amp having a perfectly flat output response. This is not a problem though with good eq work. That is why it is recommended to redo you rta work if you switch amps. When redoing the rta you might only need to bump a couple frequencies up or down a db or two to achieve the same desired response curve.
This is why when doing rta work and using a huge dsp eq there is an eq curve not a dead flat eq. The goal is smooth curve no spikes. The human ears are also more sensitive to high frequency which is why the curve tends to have a fat bottom
No. you should never have to retune unless power changes. Any decent amp will have the same sine wave
Most good full range amps claim less than 3db difference over the spectrum this means some areas will have a slight dip or hump not all amps will produce this same response
You will not hear and barely measure +/-3 DB across full range. Again, what can be measured with precision equipment won't be heard with human ears.
Truedat!
