Well, Phil, you say, and I paraphrase:
	1) Some people say that time domain behavior doesn't
matter above 5kHz or so
	2) Some people say that CD distortion is so low
that there's no sonic difference
	3) Some say (understandibly) that minute differences in
playback levels will influence listeners more

Then you say,
	"Well, how can you all be right?"

It's a nice debating technique to say that, but it's also TRUE.  
They are ALL right about what they've said.  Why?
1<-->2  Phase distortion ::= Time domain distortion
and the people who are (informedly) saying 1 and 2 are saying,
in part, the same thing.  Furthermore, 1 is simply a subset
of 2.
The people who claim 3) are pointing out (VERY correctly) that
minute <.1dB> differences in playback levels will mask ALL of
1) and 2) when the spec's are at the CD level.   

I don't understand just WHAT you even intended to say with your
article, given the incorrect (but effective in debate) assumtions of the 
first two paragraphs. <Unless the ONLY point was making debate 
that is intended only to influence uninformed people.>


Another really offensive debating technique you use is to say
...don't get into trouble until above 5kHz...

What do you mean getting into trouble? Apparently a distortion
that's 40-50dB better than any vinyl ever made, and a phase response
that's SMOOTHLY changing, rather than raggedly jumping all over the
place like a cutting lathe and mastering deck, is getting into trouble,
while the gargantuan CHANGES in group delay (let's use the relevant
terms, here) that one gets from a tape deck (not to mention the
self-erasure and scrape/flutter noise) aren't trouble at all.
I'm confused, Phil,  what are you saying, perhaps that analog
recordings are even worse, and not worth anything at all?

Didn't think so.

Do me a favor, Phil, co-post your articles to net.flame.  This is
net.audio, I'm trying to be polite, and I'm trying to keep my sheer
annoyance down to a loud scream.  If you post an article to net.flame
<where it belongs> I'll reply in the tone that I feel is really
appropriate. (If I have time and energy, I  sometimes wonder if
it all matters in net.audio.)

ENOUGH!

Everything you know is wrong!
Distortion is Fidelity
Weakness is Strength
Assertion is Truth
