I'm also using a Sony 7.1 Receiver which I picked up a little over 2 years ago, yet I have no idea if it's clipping or whatever that means or
regarding the load either. eek.
How exactly do you check for that?
And by the sounds of it, I guess I'll just stick with Open style headphones if they are indeed more accurate. Also to take advantage of DTS Master HD audio for Bluray can you even get 96hz headphones? I'm a complete noob when it comes to this, or maybe the sound that my HD555's are busting out is basically good enough.
I've also heard that you can actually buy seperate pieces like a new wire for example from Sennhesier.com incase you may have damaged a certain part of your headphones. Needing a new wire definitly springs to mind.lol
And if the clipping and load doesn't solve the problem on my receiver maybe this might do the trick.
Your amplifier is likely *not* clipping, as you say you're using a receiver (generally you'll only get this kind of problem from computer soundcards or other very low power devices - most receivers will either include a separate amplifier section for headphones, or drive the headphone output directly from the main amplifier through a filtering circuit (to protect both the amplifier and the headphones) - power is almost never an issue.
If you've pulled the wires apart, that would potentially be a source of damage to the headphones - and yes you can usually purchase replacement parts from Sennheiser; see here:http://www.sennheiserusa.com/service...rt_part-finder
Now regarding sampling frequency and audio codecs and whatnot, none of that matters in context of your headphones, that information deals with digital audio which your receiver is going to be decoding and processing before the headphones (or speakers) ever see it.
Some assorted information for you:http://en.wikipedia.org/wiki/Sampling_frequencyhttp://en.wikipedia.org/wiki/DTS-HDhttp://en.wikipedia.org/wiki/Codechttp://en.wikipedia.org/wiki/Dolby_Pro_Logic
You won't get "surround sound" from headphones, as they are stereo devices (and they should be, you only have two ears), so what your receiver (or other devices) are doing is resampling the 5.1 (or whatever) signals down to stereo as per their specifications (the specification of the codec involved). The "Theatre" mode is likely a DSP effect that your Sony is able to apply to stereo content, and is unrelated to the other formats. Similarly, Pro Logic II is a matrix decoder that is able to be applied to stereo or Dolby Surround/Pro Logic I content to simulate surround sound.
Some receivers (And even fewer outboard processors) will feature a mode called "Dolby Headphone", which is designed to take a multi-channel signal and resample it to stereo, specifically for headphone listening; results are variable - sometimes it sounds stellar, sometimes it's more or less identical to "normal" stereo.
