Which have more dynamics?

post #1 of 8
Thread Starter 

i am stuck between HD 558 and srh 840. I don't mind open or closed design. I just want superior audio quality.

which ones are better and have more dynamics?

I'm not sure what you mean by dynamics but overall, the HD558 is better. It doesn't extend as low in bass but it's to be expected from open cans. The HD558 is very well balanced, has a wide soundstage, and really no congestion. Open headphones at this price range are usually better than closed cans at everything but bass.

By dynamics, I mean the capability of headphones to react quickly to sound changes and the ability to produce quiet and loud sounds.

Right. Dynamics is normally associated with how speakers/headphones respond at loud volumes.

Your amplification and the sensitivity of the headphones will tend to affect how they respond in this regard and may be the important factor in limiting dynamics. What you need is amplification that still gives you headroom to cover peaks in the audio signal for your listening volume. According to the manufacturer specs, the SRH840 would be about 8db less sensitive than the HD558, assuming that the amp is capable of driving them about the same given their slightly different impedance. So the HD558 would likely do better with say some portable amplifiers where the amplification was limiting dynamics.

Of course, the ability of the headphones to play very loud (their maximum SPL) is a factor, too. Although that depends more on your listening volumes--could be both are capable of having the dynamics you need at your listening volume with the amplification you plan to use.

That's what I thought you meant but want sure since people sometimes like to throw that word around. Id still get the HD558.

I'm going to drive the SRH 840 with my E6. Is that enough?

Hard for anyone to predict since "enough" is based on your listening volume.

Sometimes (NOT absolutely all the time) one way to tell if an amp will have sufficient dynamic range is to look at the size of the power supply - the transformer, the power capacitors, etc - and on those criteria the E6 is out.

 

However, of course these can be relative. Aside from whether it might be enough for a given headphone (an iPad has a lot of dynamic range for a good IEM for example), one needs to consider also how loud your listening volume is and how much dynamic range (or how many instruments are playing) your music has to begin with; some might not benefit from a lot more powerful amp. Off the bat though I really wouldn't put much faith on the E6 for that, but don't immediately assume that just about any larger portable or even desktop amp would have a heck of a lot more dynamic range.
