Yeah the Sunrise even shouldn't be compared to commercial offerings, it's far better than the LD MKIII. The thing with the Project Sunrise II, is that it's mostly DIY with Jeremy and another guy at RockGrotto who designed the amp. That means that even though the commercial offerings have advantage of economies of scale, it's only to a certain extent. The Sunrise has been compared favorably to the Schiit Lyr at http://www.head-fi.org/t/601207/project-sunrise-ii-kit-review. I can paste what was said there about the Sunrise and the Lyr according to MisterRogers:
I've spent the last couple of days listening to my HE-500's with Project Sunrise II.
Compared to Lyr, Lyr has the following advantages: * Power. While PSII is in no way underpowered for these headphones, extra power equals extra headroom.
This to me, translates to slightly more air and space. * Slightly wider sound stage. Compared to Lyr, PSII has the following advantages: * Slightly better detail. * Slightly deeper sound stage. Overall, with HE-500's I could switch to PSII full time and not miss too much.
Actually, I think you can buy it on from the Project Sunrise site or on ebay for like $300, I'm not sure. I'm ready to get one, for the HD650 I'm getting since I'd like more detail of the Sunrise, better than a wide soundstage of the Lyr, but I'm deciding whether to get either the Odac, the TEAC or the Bifrost, I've heard differences between DACs in the £200-£400 range are minute, even in blind tests, I dunno, which to get.
