AKG K 701 vs Sennheiser HD 598

<< < (7/8) > >>

Gamerzhell:
@pingry: k701s need a fairly good amp/dac setup with good source material to reach its full potential, straight out of a computer/ipod it isn't gonna sound much better than the hd280. if past listening with sennheisers is anything to go by though, there should literally be a night and day difference between the k701 and hd280. the k701s are renowned for their extremely neutral sound, while sennheisers generally come slightly bass heavy and being closed should make them even more bassy.

@nyking: hd598 is a better allround headphone which can be driven to near full potential out of just about anything.

pingryanime:
Fair enough. I'll go try the headphones in the recording lab when I next get a chance. Those are hooked up to the an entire rig so I ought to be able to hear the difference.

kitamesume:
i still don't understand whats the need of an amp, if you'd ask a real electronics engineer they'd say "thats BS, it shouldn't up the sound's quality rather they'd introduce distortion"

simply put an amp is an amplifier not an enhancer, so that would mean if the power of the output from the source is loud enough without distortions and loud enough to make you deaf for the headphone then whats the point of adding an amplifier?

vuzedome:
If they're actual E&E engineers then they'd probably say something about impedance, and the need of a suitable amp to drive the heavy impedance headphones.
And then there's the sensitivity of the headphone drivers and other technical facts.

Well I'm not an engineer but if an actual engineer were to dismiss these objective facts then well, better hope they're not responsible for safety hazards in our cars.

Now anyone can claim that listening tests are all bull shit but from past experiences, some headphones do require an appropriate if not efficient amp to drive them. Take it or leave it kitamesume but until you've tried the AKG's with a decent headpone amplifier in between the headphone and an ipod, you won't know.

As I've said from the beginning, try it before you buy it.

kitamesume:
i can say there are headphones that do require amps, usually those headphones have more than 200ohms of impedance where as the 2volts Vrms isnt enough to drive it since the total power output wouldn't be over 20milliwatts which is really low for a headphone. headphones that are well under 100ohms on the other hand shouldn't need amps, although some transducers which are stiff as leather would need more than 100milliwatt to be as loud as a sensitive transducer at 20milliwatts.
so if the headphones has either a stiff transducer or high impedance, maybe even both, then i don't see the point of having an amp, a simple test is to use the raw output of the unit and see if it's max volume can reach the maximum loudness of the headphone without distorting the sound, if it does then the output shouldn't be needing any amplification.
