I wouldn't say frowned upon it's just the problem is which two amps are you comparing. There are countless implementations of the PPA and certainly more than one way you can build the CK²III. With most commercial offerings you might have a couple of choices to customize an amp but for the most part they won't represent large sonic differences. With DIY designs this is decidedly not the case.
