You confirmed my expectations.

Then why include it in a post of this type? To confuse? Or just a 
smokescreen? It was off topic for the thread, put up a separate post to 
gripe about the TCDD10's pre's. I'm in complete agreement with you on 
them based on what I've read and heard. Unless you wish to pass it off 
as a ATRAC problem...

You misunderstand who is all worried.

It's very similar to the experience mac users have to use minidisc. 
Mention that you use mac and it's very common for windows users to 
question your sanity. And you naturally respond to say why you use macs, 
and thank you no, you are perfectly sane. That does not mean mac users 
constantly are engaged in some kind of angst, we just like the record to 
be clear. In actual use a mac user has to worry over his computer less 
than a windows person. (though with OSX that's less so) We just get on 
with our lives and interests. A computer is just a tool we use, mostly 
without thinking about it. Which is why we choose macs.

The situation is very similar with minidisc. Most experienced users know 
exactly what they will get, and that's very good. When I'm recording I 
worry about soundfield composition, mic setup, gain adjustment and so 
on, ATRAC is not at all part of my worries. I might as well worry that 
the recorder case will implode, or terrorists will attack.

The folks who engage in ATRAC-angst is the anti ATRAC folks. They never 
use minidisc as a rule, have no experience with what they are talking 
about. Do some little isolated test and proclaim themselves expert on 
the subject and the experienced folks with minidisc fools. I don't at 
all mind that, unless they try and impose their religion on others. In 
particular when they try and confuse the facts and relative importance 
to beginners who don't yet have the experience to judge on their own. 
Then those using minidisc do try and provide some balance. To place all 
this in perspective. And get accused of ATRAC-angst.

Remember, this discussion started with such a beginner asking for a 
comparison of recorders. Followed by a inexperienced anti ATRAC person 
trying to pass off clipping as ATRAC, a classic ploy as I showed. It is 
important that beginners in digital recording learn to accurately 
recognize clipping and how to avoid it. Or do you not think so? They 
should certainly not look at clipping and think it's something else they 
can't fix. Let's not teach them to do that. No amount of hand waving 
will change what was attempted. Though there has been considerable 
effort on the part of Anti-ATRAC folks to sidestep the issue. The real 
issue is not ATRAC, it's confusing inexperienced beginners who want to 
learn to record nature. As such it is not a subject that can be taken to 
the minidisc groups. The buck stops here.
