It's been a month with my new AKG 551 through Fiio E17 (Treble 2, Bass 10, Gain 12)   I'm not gonna lie. Last week, suddenly the soundstage got expanded by like 100%. Back then there was almost no soundstage at all but now just suddenly it came out. Just what the hell??? Did it finally pass...

    I recently got K551 and honestly I felt like I was listening through a $5 headphone. I had the bass set to max on Fiio E17 and still I couldn't hear any deep sound at all! But now after 40 hours of burning, it's getting better and I started to prefer it over HD598 regardless of its sound...

Unfortunately, I didn't find K550 but I bought this which I believe is the new version of it.     I can't wait to listen to it once after burn-in!

Guys I tried connecting it to my PS3 via Optical cable but there is no sound. I configured my PS3 to use Optical Digital but there is still no sound.

I finally decided to buy Fiio E17 after hesitating for like 4 days every morning ><   As soon as I hooked it up with my HD 598, I expected hissing but there were none. Of course I pumped the bass to 10 since that it what I'm interested with and WOW! I swear I expected to hear "muddy" bass...

I see. I'm not that familiar with headphone amps or audio amplifiers in general but I just keep hearing that if you own a high-end headphone, you should get a good amp or a sound card like ASUS Xonar so that you get most of out of it.   The thing is, when I use EQ from sound settings on...

Hello, I'm frankly new to head-fi.org but I've been surfing it for quite a while and I had to make this thread hoping I might get an answer .   Currently I have Senneheiser HD 598 and I use it with my PC onboard soundcard (Intel mobo DH77EB) as well as with my 42" Philips HDTV through...
