But to appease anyways,
I've heard the 800s with a HeadRoom Airhead with an iPod LOD as a source and the combo was awesome. The 650s behave the same way with HeadRooms entry level portable stuff. It's a smooth, relaxed presentation that I really enjoyed. Is it the best I've heard from those headphones, nope. But it was in no way bad, disappointing or un-involving. I know it gets better, and I would bet the OP does too, but that wasn't his question. He asked if they would be worthwhile, not their best. So my answer to his question is perfectly fine."
I've had the Total Airhead together with the HD650 and felt it was a poor match. I had iBasso D2+ Boa with the HD800 and felt it was a poor match. Neither were driven close to their respective potentials. IMHO, and the opinion of many others, the HD800 needs a desk amp to fully drive them. Why would you spend $1k+ on a headphone to cheap out on a poorly matched portable amp?
