I have a headlite and I must say it's the best sounding amp I've ever owned. I've had a working pro 400, a 350x, sm-1500 and a 750x. The headlite is a bit of a warmer sounding amp, it has more of an sm series sound than the x series. There is a thread with some sound clips in it somewhere in the recordings section, just search for headlite and it should bring up the relevant Threads. Any questions pm me, I got mine from guitar guitar and they expressed some interest in stocking them.
