thegreenman, you only see what I want you to see... ;)
(Quite mysterious, eh?)
There are certain ways using multiple channels may (for the community's sake, notice the word "may") sound better than a stereo amp or monos.
Do not be overly impressed by rigs with many amps; it is not a sure indication of superior sound quality. In several respects, a more streamlined rig is preferred. It is far easier to screw up the result when multiplying functions, and it is far harder to dial in a rig to perceived perfection as well.
If you would like to see the list of amps I have reviewed, check my reviewer profile at Dagogo.com under the "Staff" tap at the top.
I just sent back some mono amps, so at the moment I have the Kinki Studio EX-M1+ Integrated Amp, the Redgum Audio Articulata Integrated Amp, and the Legacy i.V4 Ultra Amplifiers here. I have another top secret on coming soon. Sorry, I do not typically reveal the identity of review items far in advance of the article. I can tell you this; it will be a stereo amp and about 100Wpc. I suspect it would sound very good with the Legacy Whisper DSW Clarity Edition speakers you mention.
To give you some idea of how vastly amplification can range in terms of performance, the Redgum integrated amp has bested several other SS stereo and mono amps. It has terrific ability to push less efficient speakers such as electrostatic speakers. Amazing rigs can be built with monos, stereo, integrated, and multi-channels.
There is often something lost in the effort to push toward the lower power, higher efficiency end of the spectrum. When you have heard both ends many times, you understand that. A person has to make a choice between the set of attributes most desired, and you usually cannot have both.
