Music Alchemist DreamKing StanD I don't mean to bump old threads or anything, but you guys seem to know about this quite a bit. This is a comment from YouTube by someone named derbigpr50o.
"Just want to share something with people who own or think of buying these headphones. The reason why most people feel like their AKG's have no bass is because people are not amping them properly. People see in the specs that they're 62 ohm headphones, and think they're easy to drive. Well, let me tell you, as someone who owns the Sennheiser HD650 (300-550 ohms), Beyerdynamic DT880 (600 ohm) and Beyerdynamic T1 (600 - 1300 ohms), which are my highest impedance headphones (highest on the market too), and you might also assume hardest to drive, AKG K701's/Q701's are harder to power than any of them. Why? They lack sensitivity. Their sensitivity is extremelly low compared to other headphones at a similar price, and they really need a very powerful amplifier. A lot of people plug them into cheap 100-200 dollar Fiio, O2, etc. amps or soundcards (even Asus Essence ST or STX fits this category) that might look like they have power on paper, but in reality, they don't sound good at all with these headphones. These are probably one of 2 or 3 headphones under 1000 dollars that REALLY will benefit from using a high end amp. This is why you shouldn't really buy these headphones unless you can invest in a proper headphone amplifier, becuase you will be missing out on what makes these headphones so special and what made them so be so loved back before stuff like HD800's and T1's came out and skyrocketed the prices of headphones from 400-500 dollars to 1500-2000 dollars. Most headphones sound the same when plugged into a entry level $100 headamp and a $1000 higher end headamp. These? Nope...their bass extension, presence and tightness greatly increases when used with a really good amplifier, and their overall speed, attack and dynamics increase greatly compared to cheap amps while listening to the same volume, they simply sound far more lively and fun. With cheap amps like O2 you have to listen at high volumes, otherwise they sound dull, boring, flat, lacking bass or any sort of punch. With better amps, you get the fullness of music at lower volumes as well. I was shocked to find how much better my K701 and Q701's sounded when I switched from a 300 dollar chinese Little Dot Mk5 amplifier (which sounded absolutely fine with other headphones) to a 1000 dollar Musical Fidelity M1 headphone amplifier. Basically, you'll get a better sound by spending 1500 dollars on a K701 + a high end amp than by spending 1500 dollars on a 1100-1200 dollar pair of headphones and a cheap amplifier. Why? K701's are still absolutely world class headphones, if it wasn't for slight coloration in the upper midrange, I'd say they're the best at under 1000 dollars. Nothing up to that price beats them when it comes to dynamics, soundstage size, transient response, flatness of frequency response, etc. Ironically, what works against them is their low price. They're too cheap. Until a few years ago they were absolutely the best consumer grade (excluding exotic stuff like Stax) headphones in the world, better than HD600, HD650, DT880, DT990, etc. when paired with proper equipment. Now they sit too low compared to new high end headphones which costs 4-5 times more, and people who don't know anything about the history of these headphones assume they're considerably worse and that they can use them with poor equipment like it's the case with other 200-300 dollar headphones. Well, that's simply not true, and that's the reason why most people who own the K701 never get to hear what these headphones can really do."
Is what he's saying true? I'm just getting into real audio, and am recieving my first real headphone tomorrow (the K7XX's.. which is what this commenter is referring to). I'm hoping this won't be the case cause I'm not looking forward to a 1000$ dollar amp as he claims to get the most from these headphones... 200$ for the akg' were already a stretch for me lol.
