Many people still think that power supply has to be linear and
heavy to deliver great performance. In reality many designers
use large heavy transformers because of this belief - that
creates better sales (If it is heavy it has to be good). Look
at new class AB amplifiers from Jeff Rowland - all use 1MHz
SMPS and are very quiet. Black amplifier by Bel Canto claims
amazing 120dB of dynamic range. Do you think it is because of
heavy power supply? New Benchmark ABH2 - a class AB amplifier
achieved 130dB dynamic range using SMPS. Also their new DAC2
got 10dB quieter than DAC1 by using SMPS (multiple) instead of
linear power supply. From technical view point linear power
supply is a non-regulated noisy switcher.
