Hey guys, I am hoping you can help me spend my money I'm using a pair of HD-650 at home, connected to a Audio-GD Compass connected to my desktop. I've been using the Compass for a few years now and even if it wasn't presenting some hardware issues, which it is, I want to try a tube amp, which I've read forms a good combination with the HD-650. Last night, I was one click away from ordering a Schiit Bifrost and Lyr, when I decided to make one more round of research. Turns out some people don't like the fact that the Lyr is a hybrid tube amp. Those same people recommend the Valhalla or a Woo Audio WA3 over the Lyr. So, now, I'm back to researching. Fast-forward a few hours, now I'm seriously considering the WA6, a bit more expensive, yes, but I don't mind spending a little bit more if I'm already going to pull the trigger on a tube amp. But now I'm not sure which DAC to go for if I go with the WA6. So, between the Schiit mid-range non-balanced line-up (Asgard, Valhall, Lyr) and a WA6, which would you guys recommend for the HD-650? If the WA6, which DAC? The only other headphones I can think of trying in the future are the Beyerdynamic DT880 (600ohm) and maybe the HD-800s. I apologize if this post seems a bit -- scatter-brained. I'm basically thinking out-loud, and the text above is what's going through my brain right now Thanks in advance!
