For clarity I'll point out what I'm not saying. I'm not saying that the Lyris is a bad amp, on the contrary its an excellent bang for the buck amp. Nor am I saying the the 580s sound bad out of the Lyris. I think they sound good. I think the HD580s sound good out of my computer's HP out as well (I'm not talking about DAPs). I'm also not saying that the 580s need a desktop amp to sound good. The problem is I don't see that the Lyris offers much if any improvement in SQ over the computer's HP out. If anyone can hear differences in SQ with the Lyris, I'd be very interested to know what I'm missing. If 1time is just looking for greater volume alone the lyris will no doubt do him nicely. If he's looking for improved SQ, he'll probably be disappointed. I really don't see the point of using a portable with a desktop computer and the 580s when even a modest desktop will probably do much better and the HP out is at least almost as good.
Huckster: As I've stated repeatedly, yes, the Lyris provides plenty of volume but I'm not talking about volume, I'm talking about
control.
If you don't understand what I'm talking about you might skim through
this thread and focus on those post that talk about the roll of voltage and ohms in amplification. ( Please note that the over all thread does not deal directly with the 580s.) There are also many other discussions of this that would explain it better then I could if you care to look for them.
HeadphoneAddict: No nothing is broken. What I'm talking about are not huge "OMG this sounds awful!" types of problems but rather pretty subtle differences. I think the problems I've mentioned are what people are talking about when they say Senns are "dull", "veiled", "boring" , "slow", etc. Like I said not huge, but significant enough that they bugged me. Getting the GLite ameliorated these problems enough to where they don't bug me any more.
