I think stv014 is correct.. and it isn't the lack of bass extension as much as it had been just being used to the way the HD 650s colored the sound with elevated bass. But as I said in my response to him, even the HD 650s seemed to be missing something in the low-end when running directly from the Asus ESSENCE STX as opposed to the Schiit Valhalla.
I also think another part of it has just been that I was not used to the extension to the high-end.. as the HD 650s are veiled in comparison.. but I had gotten so used to that and even learned to enjoy it quite a bit.
That being said, I'm learning to appreciate the extra detail the Audeze give me. Even if it can be just a TAD more fatiguing for my ears over a longer listening session.
I'm still looking forward to getting the Schiit Lyr though. UPS tracking says it'll arrive Monday.
Just thought I'd post some impressions on this... since I was wondering about it myself.. before i got the Audeze.
To start off with.. I have a Schiit Lyr on the way, and I'm glad I do.
While they sound just fine straight out of the sound-card, the lack of bass extension is very evident.
Having upgraded from a pair of Sennheiser HD 650s running off a Schiit Valhalla, it feels like a slight downgrade right now.
But even then, there is a clear and noticeable improvement in the soundstage and general speed and recovery of the sound.
Playing with the EQ in the driver software for the Xonar, I created a flat, tilted slope toward the bass. Adding about 8db+ to the lowest 30hz frequency in the EQ controls to try and compensate a bit...
and it sounds pretty nice.
It really does blow me away how well they handle sub-bass notes without distortion at higher volumes. Tight and impactful without losing control.
So I'm really looking forward to hearing them with the proper voltage running through them.
All that being said... if you're planning to spend the money on these headphones... then plan to invest in a good, proper amp soon after you purchase them.
Mine arrives on Monday. =)
I'll update my impressions when my amp arrives.
