500+ Head-Fier
Its never a waste of space my friend we're all learning here. The Huge / LG / WA5 are all great pieces of course and will make most headphones sing. Its more the case that I feel you really need a great dac and amp for the HD800s to shine. When properly driven they have a presence and soundstage that imo is only reached by the top electrostats. Just in case it interests you, i have recently backed both the LHLabs Geek Pulse DAC and Lambert tube amp on IndieGoGo as i am also not willing to spend 10k on my chain. Im hoping that they will make a good budget system for my 800s coming in at $650 + shipping for both. I'd recommend having a read about them on these forums.
As for the camera analogy i didn't mean for it to come across as each component having an equivalent but moreso just as a general reminder than in many hobbies your gear is only as good as the weakest link. Glass is definitely a far smarter investment than bodies although with the current rate of advancement in sensor technology (sony) and lower price points of stunning glass (sigma art series) i think the lines are getting blurred.
Funny you mention that analogy as I was thinking that exact same thing and with Sony's newer SLT cameras and great sensors I am getting some stunning pics with fairly cheap glass which I like.
