Just taken a look at the internals of the Schiit, only one thing I don't like - the Alps Blue is configured PCB only, so there's nothing you can do, except maybe fit a new different pot. Volume control has a lot to do with the sound you hear, why do you think some are prepared to pay a lot of money for fancy stepped atts. My first intro to real hifi was on a forum dedicated to tube gear and in the early days there was real experimentation with components. The good old boys were all for PIO caps, most newbies soon rejected them, along with ditching carbon resistors. A big improvement was to 'shunt the pot', the pot being an Alps Blue. this can be viewed on the World-Designs forum, scroll down and look for the tweaks, it's there. It really transforms the Alps Blue into something an awful lot better. Most just used ordinary metal film resistors, I used Z foils - there is no comparison between a shunted Alps and the standard model. I don't think that Schiit intends it's punters to mod any of their gear and I don't think most want to anyway. I'm just pointing out how important to the overall sound the volume control is - it looks to be a well designed piece of gear. Using the one tube and a good one at that is nice, with adaptors you can tailor the sound to your liking. I'll bet it would sound good using a 6F8G TS RP but then any piece of gear does with that tube.
