I have a PAIR of Parasound A23 working into Magnepan MG1.6s
Pull jumpers and connect.
Intent is to go Active using a MiniDSP at some point.
Total output is the same or exceeds the prior amp, a PSAudio GCC250 which was an ICE 'D'' amp.
On paper the output is less, 400 per speaker as opposed to 500 for the GCC, but the Parasound feels stronger.
Given the 600hz crossover, which is near the 50:50 power point, I'm expecting big things when I go active. Theory tells me I could get as much as 3db additional 'juice'.

Follow Ups:
Been there..done it, moved on
Frankly it made small if Any differences on MY setup.
Subsequent replacement by a single low power Firstwatt Amp was an epiphany upgrade
Clearly doubling up on amps can make some differences,
under 2 basic scenarios though:
A) the Speakers used are an interesting load
B) the single amp is of erm Suspect performance (completely inadequate to needs)
.. Double amps essentially increase headroom ..On the other hand Line level crossovers (active or passive) coupled with an Amp per channel can make significant differences.
Far more than merely doubling up amps does.

You're absolutely correct just as using two mono block amps have no advantage over using one stereo amp lol.And to think having the highs and mids not sharing the main filter cap with the bass driver doesn't make a difference ...............?
And to think all of those engineers, manufacturers, etc just wasted their time and money designing and building dual mono amps that apparently have absolutely no advantages over a typically designed stereo amp when all they needed to do was ask you and you could have set them straight.

How far do you pull your MG1s from the wall?

Panels sound best when 4 feet or more from the front wall. This timing gives the ear / brain a full chance to distinguish the first arrival from the reflection.
