Single-ended operation avoids the recombinant errors that arise when an
audio signal -- split into phase and anti-phase to be separately amplified
as in push/pull designs -- is reassembled. In a single-ended design, the
signal remains whole from input to output.
The audible benefits? A sense of naturalness and realism -- often referred
to as "the single-ended magic" -- that p/p efforts lack nearly
by definition. The disadvantages? Reduced power since a single output device
is now asked to do the job for which a p/p design would employ at least
two, and in most cases multiple twin banks of paralleled devices.
Art Audio's single-ended designs are expressively designed to drive even
speaker loads that traditional SETs of equivalent output ratings cannot.
The model-specific pages include actual owner feedback to clearly indicate
what speaker loads each amp is suitable for. However, there naturally are
limits to what can be achieved even wiith brilliant design and modern high-current
That is why Art Audio makes available custom monoblock SET versions of the
PX-25 and Jota. They're designed to wring the utmost of power and drive
out of their respective circuitry.
