Does using two power supplies, one for each channel, improve sound perceptionthe improvement quality or not?
In the case of power supplies with +/- I could say that something has improved. Not in the case of the power supply only with +.

Edit: the correct term is quality improvement

If you have a one power supply of good quality,
I say it is just as good as two power supplies.
It is not a matter of one or two. It is more important with good quality.

Yes, a quality power supply makes the difference.
However, I see many projects that use two power supplies.

"improve sound perception"
Is kind of subjective , even if you can measure differences.
For a poweramp which usually has unregulated power supply , I would use seperate transformers. For a HP amp I chose a compromise . 1 transformer and rectifier , but after the mosfet on/off switches , L & R get their own CRC and regulators. Whether that really improves sound perception is a good question but it can't hurt and stays affordable.

Actually; and please take this in the spirit it is intended and that is to help with advancing your command of English; it would technically be more correctly written as, 'A qualitative improvement'.
Ha! sorry I just realised I bumped a thread for that.
I like a more brute force approach, using unregulated single supply with (2) 4700uf 35v per rail for each 15v rail.
One supply is absolutely fine. Whatever your budget one good supply is likely superior to two cheaper ones.
And its not as if the power requirements are that high.
