Hi there! So I am completely new to the whole "Hi-Fi" stuff - never owned a headphone-amp or anything. Now as you can tell from the title i'm lookin for a tube-amp for somwhere around 400$. If there is another one, I just dont know about, please let me know ... I'm not limiting to these 3 options. I heard, that the LD and Schiit are rly good for the price and i dont care too much about the _no_rolling_ of the valhalla as of now. I just found no comparison of these so I'm kinda lost here... Also: Is the 'special edition' of the LD worth it's hundred bucks? I listen to all sorts of music (mostly Metal/Rock - but also psytrance and.. well, anything - so i'd prefer a balanced 'allround' solution) and i'll be getting a "Cambridge Audio DAC magic" as soon as a friend of mine gets to the UK in september.. I'd appreciate any help!
