Thanks, HeadphoneAddict. I'll look for them on eBay. I am also interested in the 300mAh Powerex...
And, the most important thing: I got my Lyrix!!!
It's faster than I expected after reading all the comments here. I was notified 3/28, and got it 4/5, so it's 8 days including weekends. Not slow at all.
I only have about 6 hours on it, because I haven't got my battery and extra adapter. I used the adapter for my laptop to power my Lyrix, and it worked fine. However, I need to use my laptop, so I couldn't listen to my Lyrix for too long. I'll get an extra adapter soon, and batteries too.
The improvement is subtle for now. The music is "flat" when I listen directly to the laptop, and it's more full and "round" through my Lyrix. However, the difference is not dramatic. I think it'll be better after I have more hours on Lyrix. I've also read somewhere that the headphone out on IBM ThinkPad laptop is very good. If true, then this probably explains the less dramatic difference.
I can here background noise from my laptop especially when I choose high gain for HD-580. I know it's from my laptop because I don't hear any noice when I use my PDA as source. This makes me want to buy a USB DAC even more... However, I didn't notice any noise if I plug HD-580 (or other headphone) directly to my laptop. I am not sure why.
I don't have an iPod or any other MP3 player (yeah, it's hard to believe...), so I am not sure how the Lyrix performs compared to the MP3 output.
OK, I guess that's all for now. I'll update the progress I have on my Lyrix.
