Just yesterday, I won the Audio-GD NFB-10.2 from Toxic Cables. Since they're in the UK, the amp that's getting sent to me is 220V, and I live in the US, so I need a step up transformer. Which one would suffice for a desktop amp like that? I've had my eyes...

There's a cable I've been looking at for my HiFiMan HE-400's. It's the 2.5 meter cable from Q-audio (http://www.q-audio.com/). If that cable was DIY'd, how much would the materials cost? They say they're using 220 strand litz wire and silk sleeving, terminated to a 1/4".

I've decided to invest in HiFiMan's HE-400's but before I pull the trigger, I want to get a good deal. I hear stories about people getting the HE-400 for ~$350 but I can only find them for $400. Will they ever be on sale? I checked a few places but it seems as if they're all selling for $400. If...

I want to spend about $400 ideally but $500 max on a new pair of headphones. I don't have any sort of amp I can use right now, but eventually I'll invest in an amp. What kind of amp should I get with that particular headphone, I know there are a lot, so I'll limit my budget there to about $250...

I'm not too good with audio, at ALL, so would someone mind explaining everything to me? I want to improve the sound quality of my headphones and speakers, I have the Sennheiser HD 280 Pro's and my speakers are the KRK Rokit 5's. I heard that having a DAC can make them both sound better, but...

I have some background info. My budget is $200, which I can stretch if I have to. I live in the US (California, to be specific). I mostly listen to dubstep and electronic music in general, I'll also use this for gaming (Not that important though, because I can also use my headset instead), and...

I'm super bad with everything audio. Right now I download 320kbps MP3 files, but when I look at the file formats, I see more than one. I know that there's a better quality format than that, so what's the best format that I can download in? Also, it's my understanding that I need an decompresser...
