yes, it's a pity, but understandable - and not only for the sarcasm following...
According to a developer no more than 3% of the downloads of his $99 device resulted in a purchase.
Probably 2% were convinced anyway (and just wanted to confirm their decision), so for a 1% success rate I wouldn't even think about it.
Even betting on horse races is more profitable...
on the other hand the sound examples aren't that bad - regarding 'sound'. One simply has to ignore the 'musical' content

at least it worked with the Profit5 (in my case) - which was the first CWA device I couldn't demo.
I bought Zarg's QWave because(!) of an audio example and didn't even ask for a demo - it would have been a waste of time
I completely understand your point, but at least there IS some usable information by what people 'review' here, what's used in the 'music section' of planetZ, and some experience with CWA sound in general (it doesn't sound bad just overnite).
cheers, Tom
