Yeah, I'm running the X-AMP as well. Wonderful piece of gear.
Here's some reviews on the X-AMP:

For those of you who are wondering about reamping, it's pretty simple stuff:
Send your recorded DI track to a discrete mono ouput on your soundcard. Set the level on that channel to 0. Run the line level out to your amp, place your reamp box before the amp. Set your reamp box's level to 0. Then plug in your pedals or whatever & plug in your amp & go. It's that simple. If you need a quieter signal for a cleaner tone, you can pull back the reamp box's trim control, as it's best to make the adjustment there instead of in the DAW.
When I'm doing reamping, I think of the send levels & trim control as "volume pots" on a guitar. Well, that's the analogy I keep telling myself, anyway & it works. Seriously, it's just idiot proof.
I'm only speaking for using the X-AMP, which is an active box. The Redeye & Cubinerti might be slightly different, I'm not sure: I've never used them.
Of course the real challenge when reamping isn't so much how to hook things up, it's where to place the mics, what type of technique, what type of amp, cabinet, pedals, etc, etc, etc, that we all obsess over constantly.
I've put a good eight years into learning how to mic a guitar amp & just about went insane learing how to do the "Fredman Technique." Fortunately, some of you guys really dig the sounds I'm getting & want those sounds for your own projects. Hence the prepping guide.
