How long have you use it?

</ul>

I have used it for 2 days
<ul>

Have you tried many other models before buying it?

</ul>

before I was on the NS7 Xponent is a very good machine to start on this kind of support
<ul>

With experience, you do again this choice? ...

</ul>

without hesitation, a veritable war machine
<ul>

What is so special that you like most and least?

</ul>

most: the sound is simply superior to the Xponent (it feels much the 24 bit NS7), the grip (... welcome to the pro), stability (M-Audio will have to work at this level one)
the monk must be a pain in the ass to find fault (it is only my opinion ...)
<ul>

How would you rate the quality / price?

</ul>

expensive ... but it's worth, then I think you know what you want (it's still a Rolls)
