Bigger is a meaningless metric. Transformers are not rated on how "big" they are but on the voltage and current they produce.

A - The power transformer's sizeTry this first experience: take a small current device (solid state or valve) as preamplifier, dac, phono stage...
Listen it (I guess the original transformer is a 50VA).
Take the same device and change only the transformer by a 160VA. Listen it.
Now, you can change the transformer by a 300VA and listen.
Step by step with this experience, the sound's quality increase. Indeed the sound is less metallic, more natural, your amplifier seems to be powerful and low frequencies are more present... Why do devices which need only 10W, sound better with a 300VA transformer than a 50VA transformer?By increasing the transformer's size, lots of things change:
The self is a tank of energy,
It works easily and faster,
Bigger transformer is a good mains filter. (Device is protected from high frequency pollution generated by dimmer switch, switching power supply, electric motor... and protected from low frequency pollution: your own audio power amplifier!)

Depending upon the current consumption of the "10W" circuit, a "50VA" transformer may well be insufficient in the first place. The circuit could be current-starved by such a transformer. In which case, it would be no wonder that the 300VA transformer would sound better. Much better.
... I suspect that what he means by bigger, and the basis of bigger that I am interested in is in a larger transformer of the same type, made in a very similar way with higher VA rating. Not comparing different types of smaller or larger transformers to each other. This thesis, of lower noise with a higher VA transformer of the same type is his thesis, not mine. T456
It is irrelevant whose "thesis" it is. The point is a simple one: bigger is not a metric with which we measure power transformers.
If the hypothesis is that a power transformer with a higher VA rating will allow less noise into a system then you need to state it that way.
That's what I just did. Bigger= higher VA of the same type of transformer. What more do you want?

For you to stop posting all this crap that you found on the internet, and acting as if you know what you are talking about.
No chance of that though.
