I just received my Xenos amp. I got the x1ha-epc and initial impressions are great. I ran it back and forth against my bithead and I feel the xenos has the upper hand in every way. It's really hard to compare the two, but i did notice the xenos pushes out lower notes and it just sounds like there is 'more' to the music.
the size is my only concern. I can't really see myself taking this everywhere all the time. if i have a bag, no problem. but there is NO WAY this will go in any of my pockets and in a jacket would be pretty cumbersome...
It is very well constructed. I really like the solid clicking of the jacks. At first I thought there was maybe something wrong with them since I've never had to push my headphone or line out so hard. They seem really snug. And don't get me wrong it's not so hard where you are forcing the connects in. Just different than what i'm used to in my very limited experience with this wonderful gear
Perhaps most amps are like this!
There is no hiss unless i really crank up my hd595 to volumes WAY WAY past what a normal person would listen to. i've yet to try it with my IEM's super.fi 5pro.
TOnight I'm going to really listen once the ipod charges up and will give a some pics and a better review for ya'll.
FWIW, i'm using hd595, alo copper dock, 30gb 5g ipod.
