Wow, there's some misconceptions floating around here...
To put it up top - I work for Mandriva. I wasn't involved in this particular deal and these are not official company statements, but obviously I should mention that.
One, the problem is not, per se, losing business to Microsoft. As...
I think the guy who wrote that article is getting his ACPI and his APIC confused. In Linux, at least, you can disable APIC (which does IRQ routing) without disabling ACPI. I'd assume you can do the same on Windows.
Actually, I find this kind of post depressing. Disregarding the first issue, which was your fault, they sold you a defective product (sub buzz), and after you prodded them several times, they replaced it. This constitutes great service which is worthy of a forum post? I'd say anything _less_ is...
jason: all the firestone amps are designed to be general-purpose (they power anything from Grados to 600ohm old-style AKGs to well over 100dB), so the Beyond should power the HD580s fine. You might want to get in touch with someone from Firestone and ask if they'd recommend the Beyond or the...
Yeah, "USB is better quality" is frankly bullcrap. Think of it like this: you're paying an extra $13. whoopee. but that extra $13 has to pay for basically an entire sound card in the headphones. Unless your sound card is really, really, really terrible, the USB headset will likely sound worse...
Everything will sound better.
Amps are necessary with high-impedence headphones to actually make them loud enough to listen to. They do this by increasing the level of voltage of the signal sent to the headphones. Their other function is to increase the level of current, which can improve the...
actually, there's a couple of guys on head-fi who rate phillips pretty high for cheap stuff. if you can't find a pair of the senns to compare, don't sweat it, the phillips are probably fine...
Buffering the output stage in a simple amp design (like the cmoy) basically increases the level of current delivered, which is what low-impedence cans want from an amp (they don't need voltage since they're, well, low-impedence). So you shouldn't be looking for buffers so much as an amp designed...
The headphone socket on the z5300s is the single worst piece of audio equipment I've ever had the displeasure of listening to. It's just hideous - noisy, distorted and massively underpowered. Plug the cans directly into your soundcard and they'll sound a lot better. If you're still not happy...
