Hi all,
I'll probably post this as a separate thread, but I want to give some thoughts/impressions on the Teton/HD800 pairing - based on the Dubstepgirl HPguru review. I bought the Teton, along with the USAF 596, Tung Sol 5998, and metal base Sylvania 6SN7W tubes, and others. Ended up favoring the 6528 over the 5998. HOWEVER - tube rolling is all in vain, I PEQ'ed this complement to neutral, and frankly I cannot believe how people praise the sound of these amp/HP combos otherwise. With my PEQ, the sound is unbelievable, velvety, smooth, full ranged. As an example, I was modding a pair of HD6XX with wood cups, and quite enjoying them, I was listening to Ulver's Assassination of Julius Caesar coming home on my portable rig (Hugo2). When I got home, I transferred to my home chain (plugged the Hugo2 to Teton-HD800) and turned on the PEQ I had been tweaking for the HD800 - and OMG, it's night and day, basically like going from rags to silk, well, to be honest, it sounded immediately better, but the real revelation was going back to the plain un'EQd HD6XX - what sounded amazing on the way over, now was harsh, loud, mids too forward, lacking treble details, bass too boomy.
I'll be honest, I've PEQ'd other headphones before, and adding the Teton has made that easier for my HD800, but in truth, I once again find that, assuming one gets a nice headphone and decent enough amp, learning to PEQ to neutral is probably the most important step to truly great sound. I am amazed with my PEQ-Hugo2-Teton-HD800 chain now, and I wonder if even some of these reviewers have ever heard such a great sound, with their as-is gear. Wish I could get my hands on a HE-1 rig...
