Hey Atalwar, just wondering what a/d & d/a converter, decent headroom and good native h/w sample rate mean?
I just play my guitar and record sometimes, I don't know all the technical stuff behind it all, but would sure like to know more!
Thanks

Kyle,
The a/d conversion,samplerate are the essential parts of the digital domain/recording. as the input needs to be converted to digital numbers before it gets processed. How good this conversion is depends on a lot of factors like quality of op-amps,the dsp engine etc and this stands the units apart.
What i meant was look for a unit that gives you the numbers/quality from today's standard.
The issue i have noticed with my podxt atleast is that it has a very limited range and a very non standard/low sample rate (39062.5 hz) as opposed to atleast 44.1 Khz requred for good quality and atleast 48000 Hz required for decent quality (96000 and above for pro quality). The Quality is not that much of a concern if you are playing live , but when recording you can just hear the strange things and lack of some tone and it not just cutting the mix. To be safe you would be better off with a X3 unit as they are newer units and might have better chips there i think but do check the specs for sure.
Also a important thing in sample rate conversion (a/d conversion) is that it should be hardware based for such units dealing with external analog input, if its just the driver that's giving you a higher samplerate by resampling then it not going to sound much good at all as its trying to compensate for something that just ain't there in the first place (because the dsp didn't capture it).
Excuse Me if it sounds like a tele shopping ad 
For years I was not getting a very good tone out of pod, thinking that it was my guitar or pickups etc and have ruined every possible screw on the pickups etc, few days back i plugged a cheap usb m-audio interface in there was quite a noticeable difference. Just To check, i tried a high quality firewire interface from a vocalist friend and the difference was Depressing.
