Melbguy1, to hear my personal opinion of Apogees take a look at my response to the other ongoing thread here entitled "TSW Apogee Diva Ultimates Any Good"? I will add to it that, as I had mentioned before, I think the room size, in conjunction with ideal electronics and careful placement will be the deciding factor in which model Apogees you choose...
As for electronics, my Tube Research Labs are also something of a 'niche' product in as much as it is a small, hand - built designer product as compared to something like the excellent Conrad Johnsons you mention (I am a former CJ owner and LOVED my Premier 12 amps which I would never have given up if it hadn't been to use them as $$$$ for their replacements, my current TRL monos...).
Paul, (Mr. TRL) isn't especially 'entwined' with reviews, advertisements...or even touting measurements...it's more a word-of-mouth type company who simply crafts his product sort of the old fashioned point to point (tedious!) way and lets his products speak for themselves. Great stuff, long wait list...very nice guy. Oh yes and also: end of road/"done looking" performance.
Unfortunately I have never heard the Vitus amps but I do agree with your philosophy about all the seemingly less important factors adding up to make a REAL difference.
Stick with it.
