Seriously, Prednisone is some serious stuff d00d. Are you going to be ok?
I'm surprised I'm not dead. Swollen throat and lymph glands for five days straight and no solid food until just a few days ago.
Anyways, on the Vahalla amp: it's output impedance is 30 ohms. That's rather high and makes it unsuitable for anything other than the HD558, HD600, HD650, HD800, 250/600 ohm Beyers, etc. An exception could be made for Grados, where the Vahalla even provides agreeable coloration for them. Orthos are highly NOT recommended. I've tried HE-400, HE-500, etc. with the Vahalla. Results were not good. The Vahalla is a tubey sounding amp (lush, syrupy, soft, etc.) and I got it for this reason.
With Vali, one can get by with HE-400, Paradox, MadDog, LCD2, etc. It's very different sounding from the Vahalla. Much clearer sounding, more resolving, faster, etc.
The Bottlehead Crack has an even higher output impedance than the Vahalla at 120ohms. Again limited to the usual high impedance headphones. With the speedball upgrade, the Crack is really a great amp. More accurate sounding than tubey. I actually feel the Crack is a better sounding amp than the Vahalla. The downside of course if that you have to put it together.
Maybe I should make a "Guide to Schiit Amps".
