I'm glad the sun is shining and birds flying..:-)

You confuse me...I found a circuit for car preamp and the designer also
design a switching PSU with this "artificial earth" I just wondered if I can
do it other way,

Me ? Today nothing is bothering me ! the sun is shining, the birds are
singing... ;o)
But your amplifier outputs will be heavy bothered if you'll supply it from
a switching one, mainly because the supply can't follow fast load
current change. As an example a common PC supply has 1 to 2V noise on +5V
line. A small noise on your amplifier input will gave you a lot of
problems.
