(saw the other thread about this, but it was 12years old and didn't want to grave dig it
)
As the title says, I'm making a small headphone amp and it requires split/dual power supply of 2x12V.
Now I've checked out this schematic and these two comments about the sound being better with the virtual ground circuit.

From the other thread:
The amp is with TPA6120 chip, and I planned on getting a new transformer with two outputs but I already have the 24V single output one.
So, should I continue building with the current transformer that I have and go for a virtual ground power supply? Or get a new dual output one, and build classic symmetrical power supply?

From head-fi:
Although a simple and inexpensive virtual ground solution, some audio designs will sound better when using it. For example, when powering a headphone amplifier with this circuit the bass notes may sound considerably clearer and more life like. The reason for this unusually good performance may be that the voltage regulators create an "unbudgable ground" - holding the ground point in place very firmly compared to other circuits, virtual or not.
From the other thread:
I only have experience from headphone amplifiers, but I've found active virtual ground channel to sound better than passive (relying on capacitor quality). I've never used fancy capacitors though, just Panasonic FM, Sanyo WX and such.
