That's crazy, although I suppose it's nice to know your amplifiers will drive your speakers to mechanical overload without clipping!
Yeah, my question was about how the individual ones measured as opposed to what the specs are. I suspect crossovers are particularly susceptible to variations in performance from unit to unit since the rolloff slope, frequency and phase is particularly sensitive to the actual component values, on which there will be a tolerance. The specs of many loudspeakers are similar or identical but they can sound very different.I'm sure the data is available if you care to search but the ones I have to hand;

I believe there are/were measurable differences. My point is the threshold(these all have very good numbers) and an opinion that it is how these parameters combine that can account for the differences we hear.
What about recidivists?My question remains, assuming we have a consensus between objectivists(TM) and subjectivists(TM) that amplifier A and amplifier B sound different, and there are measurements which back this up:
what measured parameters, and by how much would they need to be different?
Volume pots selector switches capacitors and resistors sound difference even though the same values.
A Alps blue and a Noble and a Dact sound very different with the noble having a warmer fuller darker sound to the Alps and the dact sounds clearer and brighter like a Arcam amp v a cyrus.
If you cant hear this you have no resolution in your ears or your system.
Can I just digress slightly in the opposite direction?
Let us assume, for the sake of argument, that we have a pair of amplifiers on which there is general agreement that they sound different. We may then assume and agree that they will measure differently, too.
To suggest a difference: one amplifier is more exciting and involving than the other. The music sounds more dynamic, the musicians sound more skilled and committed to the music, their sense of timing and pitch is more obvious and 'right'. Everything is just much more enjoyable and fun to listen to.
Assuming that the nominal power output is the same for both, what other parameters could be 'in-play' here, and what sort of difference in the values of those parameters would be necessary, or indeed audible?

Hi just a theory, but most amp designs are pretty competent and have the ability to meausure the same. So it must be down to the quality of the components used.
If anyone doubts this I'm sure that regular contributors to the DIY section of Pink may enlighten us all.
Component swapping is the most fruitful of all DIY audio pastimes.
It may sound like heresy but some resistors are thought to sound better one way round also non polarised caps.
In that case, I suggest an amp with subtitles.
Tweeter, I'm re-tuning my TV, it's taken hours, so much so I've missed the reason why I was doing it in the first place, which was to watch the Wimbledon final.
I gather from the tenor of your remark you're having a shit day, too. Lighten up.
