Switching and linear power supplies in hi-fi

Andy2 - I think the majority of digital front end equipment
use SMPS units, but most analog devises are still running
on linears.

With good design and quality parts, SMPS units can perform
very well. Their lower cost, weight and lower power consumption makes them very attractive.

Nighthawk- nice to hear from someone that understands
the potential of a SMPS when proper filtering and regulation
are applied. FYI- on the input side, these supplies also benefit from better prerectification AC line filters,high speed diodes and faster primary filters.

Andy2- if your digital equipment uses a SMPS, reducing its' output noise will make a major improvement in sound quality. The more digital devises that are in the circuit
path, the greater the potential improvement.
