Yes... I have read quite a few review comments re: the Phonitor...
... and... here are some of the several that impressed me... which suggest it is the unique soundstage that most distinguishes the Phonitor... particularly... as it relates to the introduction of the Auditor.

Moreover... its not remotely rational that SPL could have "discovered" some new design that would cause the sound quality of their amps to well exceed the many other great amps in their price ranges... or... much lower (in the case of various DIY / boutique amps)... except for the reports of "speaker-like soundstage" in the case of the Phonitor.
However... it is rational that they might have developed some new approach to processing the sound that would produce a speaker like soundstage that would distinguish the Phonitor... or... the Auditor, should they add the sound processing controls to it. That is most interesting aspect of the Phonitor, by far.
After all Smyth seems to have done so...
Which is, after all, my primary interest in the SPL, and Smyth products - the other more commonplace aspects of their sound quality, are of little interest to me - since they're provided by many other products, at more competitive prices (particularly in the case of DIY / boutique amps) - back to the "value proposition."
Nor, except in the case of the Chinese made amps, is there any rational argument that DIY / boutique amps do not provide a much greater "value proposition" than virtually all commercial products. Is there an exception somewhere... perhaps... but, I know of none. Do some commercial amps sound very good... perhaps, as good as DIY / boutique amps - sure... but... typically at much higher prices.
So... for me... the only rational justification for compromising the focus on the "value proposition" is... "all together now"... some unique aspect of these products, which create a realistic, speaker-like, soundstage... which is paticularly noteworthy, since these are seemingly the only two products (the Phonitor and the Realiser) that suggest they provide that (so far as I'm aware). And... in the case of the Realiser... it is really unique... perhaps "revolutionary." Such a unique quality... might justify their higher prices - at least until a competitor is available.
