A - The power transformer's size

Try 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!)
