A regulated supply-rail voltage means that the amplifier can be made to approximate more closely to a perfect voltage source, which would give twice the power into 4 O than it gives into 8 O. This is considered to have marketing advantages in some circles, though it is not clear why you would want to operate an amplifier on the verge of clipping.

signal portions and other sensitive circuits for the best performance. For an audio power amplifier, regulated supplies need high bandwidth for good audio performance. The complexity and cost for such a power supply design may not be acceptable. Most linear regulator ICs do not have high bandwidth and

The GT-102 has an electronically regulated power supply. That makes it unusual among audio power amplifers. But in some ways, it offers an advantage similar to class A operation. Class A amplifiers can be among the most linear of amplifiers, and the least efficient. They draw a constant current from the power supply, no matter what signal is being delivered …

A regulated amplifier power supply tries to maintain a steady output voltage. As the input supply voltage sags it will try to draw an increasing amount of current. As many of us know, it gets expensive to increase the current supply (high output alternator, large gauge wire, etc.). Barry Schanz Enterprises, LLC dba Mobile Audio Academy F fly_marlin

Unfortunately, most audio products (DACs, amplifiers, servers) will require a custom solution. In essence, a better power supply will sonically “align” the complex analog and digital signal into something that’s properly outlined and shaped. This alignment is responsible for the tighter lines and an overall more insightful listening experience.
