OH gawd, to much work
any one ever try the iGrado, I was thinking about picking one up and DAMN my indeed is NOISY as crap, which means I really need to look into a better tube as that noise is really getting to me, I miss the WARMTH of the tube but NOT the excessive noise >.> that thing is NOT for sensitive cans xD
I don't necessarily want to send you off on another buying spree, but I think the noise is due to the Indeed circuit, not the tube. After the first minute or two warming up, Zigis' amp is basically background noise-free. I've only used decent tubes with it (a generic Amperex made in Holland circa 1970, a Sylvania JAN 6DJ8 of unknown vintage, two 1970's Amperex Bugle Boys, and 4 Russian Vokshod 6N23P tubes), but none have been noisy. The Q701 might have dampened the background noise somewhat, but 62 Ohm impedance isn't exactly a high dampening factor.
On another note, right now is an exciting time for graphics cards. New nVidia cards have just been released within the mid-range budget, and are reducing the prices for some quite competent graphics. I'm having a hard time picking between a $180 GTX 570 with a $30 rebate, the new $175 GTX 650 Ti Boost, or a $205 GTX 660 with a $20 rebate. Kiiiinda wanna pick the cheapest, and then snag the next X-Fi Ti HD sale or a Z-series sound card, but it might also be good to stretch my budget just a little for the GTX 660 with better power consumption rating. We be doing some immersive gaming soon, neh?
