About the Vali and grain, I've noticed it improves with warm up so far as grain is concerned... By the way, Is this good with the hd800? http://marketplace.lhlabs.com/products/pulse-xfi-dac-headphone-amplifier
I was an anti-cable believer until I heard it with my iems : the Linum BaX does change my H8P signature and Piotr from Custom Art measured it by FR-ing Pro330v2 iems with stock cables and with BaX (and the resulting measurements prooved there is indeed a difference).However, I'm still not a cable-believer in that, in my experience, it brings differences ranging from 0% to 0,5% (numbers pulled out of my ass to give an idea), and only with some iems, not all. And all the difference I have seen seemed to be restricted to pure signature (the BaX giving an ever so slight V-shape).As a result, I would not focus on cables to yield anything sensible. And that is without taking into account $$$ to yield those results...
Linum cables purposefully add resistance. Bax- 1.5 ohmMusic- 2.0 ohmVocal- 4.5 ohmI think the numbers above are correct; need to double check the product pages. This is one of the reasons I'm looking forward to the Super BaX- not only does it not tangle but it's only 0.75 ohm.
Anybody here have experience with the OTL amp built by 2359Glenn over at Head-Fi? Supposedly designed and voiced with the HD650 and/or HD800 in mind.Threads/links for reference: 2359glenn | studio (Head-Fi)Tweak-Fi thread re: OTL amplifier
