Fantastic video from the ever reliable and knowledgeable Erin. It should please both camps.

Don't you think asking for lab-style results from Joe Public is a bit of a tall order? I do realise that this means statements so made will be opinion and not fact.Very good video, as he provided verifiable evidence of the differences (Unlike some posters in forums)
I agree, however the problem comes when they present their opinion as fact, which means verifiable evidence is required.Don't you think asking for lab-style results from Joe Public is a bit of a tall order? I do realise that this means statements so made will be opinion and not fact.
Even if you have, it doesn't mean they all sound the same.I reckon the thread title can be answered with a simple question:
Have you ever changed amps and heard NO change in sound?
You've misunderstood.Even if you have, it doesn't mean they all sound the same.
Got to be honest and say that I'm not a fan of generalisation.Indeed some amps are " Tuned " Rega sweet sounding
Until the dissatisfaction kicks in.If amplifiers do not sound different, then let us all go out and buy the cheapest smallest amplifier from China and we will all be happy.
Some people have done just that - saved a fortune and never look back.If amplifiers do not sound different, then let us all go out and buy the cheapest smallest amplifier from China and we will all be happy.
You put it so succinctly, enjoyed the read. 🙂Power amplifiers definitely sound different, they also sound different in different ways depending on which loudspeakers they are driving. There are very good technical reasons why, based on power supply stability (as had been mentioned) output stage configuration and component matching (class A, class AB, class B, class D) and feedback loop stability etc.
It is quite possible to measure these differences and amplifier designers will no doubt have done so. In most cases there are compromises made based on cost and marketability. However nothing is perfect and so even cost no object amps will have done differences.
It's worth noting that an amplifier will sound different based on the load the cloudspeaker presents and it is often the more efficient speakers that can show up amplifier inadequacies as they are not only efficient at converting electrical energy to sound energy (i.e. motion) but also motion into electrical energy. The amp should sink signals sent back into its output by the speaker (damping factor) without distorting it out becoming unstable, this isn't always the case and is often why an amp that sounds fine with one system doesn't with another.
