Would like to put an amp between them and was thinking the FiiO E09K is the way to go. My thought is I want to pick something that is going to be somewhat future proof in case I decide to step up to something like the AKG K701 can. Would like to hear some feedback from everyone. Is the E09K the right way to go? Is there something else you'd recommend?

Also, kind of a separate question, what's the point of the adding the E07K or E17 to the E09K?

I believe the Schiit Magni headphone amplifier, which has a much lower headphone output impedance, then the E9/E09K, would work better with the 32-Ohm ATH-AD700.

 

Adding (mounting) the E07K or E17 to the E09K allows the E09K to use the E07K/E17 DAC feature.

So pairing amp to a system is dependent on the impedance of the headphones? Hmm, I'm a bit confused and it really starts with my lack of understanding what basic specifications mean I think. If anyone can point me in the right direction, that would be helpful.

Basically, It's preferred to have the impedance (Ohms) of the headphones to have 8 times (or more) the impedance of whatever jack they are plugged into.

But, I can plug 50-Ohm headphones into a headphone output jack with 10-Ohms and everything sounds fine

(Others on this forum can explain this stuff in more detail on this subject).

Then some headphones are picky with the source's Amp ic and design just as well with the design of different external amps.

Not sure if this is the right topic… so I have been using headphones with my PC for gaming and films (PC is hooked up to my TV) but I think I want to step up to virtual surround.

I need to use HDMI, but I seem to remember reading that you can still add a soundcard for 3D audio processing, and have it output via another device. (Output must be stereo LPCM via HDMI) Is that correct?

If so, then the sound card DAC quality etc. doesn’t matter at all, only the options available.

Is there any one card I can buy to get all the current options? If not, what is the best choice? From listening to some demo videos, it seems like Dolby Headphone just creates a flat 2D sound field and adds a ton of reverb on everything.

StudioSound,
There is not one card with all virtual surround options included, many of the different surround processing methods are proprietary to a particular manufacturer. I have a write-up explaining different sound processing methods, here: http://www.head-fi.org/t/646786/evshrugs-if-i-knew-then-what-i-know-now-discussion-journal#post_9067400

Secondly, you can send video out through HDMI and send audio through a separate connection. That's what I did for my Xbox, and it's even easier with a PC. Creative sells the soundcards with 3D virtual surround, if there are 3D positional cues available in the source material. If you can catch Creative's X-Fi Titanium HD on sale for around $110, that card has the most compatibility – for old and new games – but for mostly new games (and movies of course) the newer Creative Z-series cards (Z, Zx, ZxR) are also supposed to be worth consideration and have upgraded amping capability.

So is the best card to go with the X-Fi Titanium HD, as it looks like it supports CMSS-3D (3D surround) and THX TruStudio Pro? (2D surround)


It seems most other cards will only support one of the other formats, and CMSS-3D has been dropped from newer Creative cards. I wish I could just pay a license fee, as it's all done in software now anyway, right?

 

 

I need HDMI for a couple of reasons:

  1. I don't want to run another 50ft of cable through the walls - especially not unbalanced analogue audio.
  2. If I don't go through HDMI, the sound is out of sync with my TV. (and the latency is variable, even if there were a way to delay the audio)
post #1298 of 3074
Variable? Gee... dunno what the ideal solution is, guess you'll just have to work on that one.

And yeah, I think THX is limited to 2D in the Ti HD. Remember movies will mostly be just 2D surround source material anyway. I wish I could just hear proper demos of all the different processing algorithms, and buy just the one that works best for me!
post #1299 of 3074

I think HDMI could be problematic. I mean I've heard Nameless say you can pass the DSP effects through USB and it would work, but he said it had a big negative impact on the sound quality. Also, considering you would be running the HDMI from your graphics card, it might not even be possible.

I'm not sure if there's any soundcard on the market right now with HDMI. It seems as though they've gone by the wayside. I'm in a similar boat- the PC is far away from my TV and in a closet and I want simulated surround sound on my Headphones (mainly for movies, not games).

What do you currently have your headphones connected to? The PC? A receiver?

I actually run HDMI out of my video card, with audio, to my den's receiver. I run the other HDMI out to a bedroom TV - the receiver in there doesn't have HDMI so I run optical out of the onboard sound. I do not experience latency.

Depending on how you intend to hook up your headphones, you wouldn't necessarily be running analogue cables. You could potentially run optical or coax out.

 

Note: I'm using an nvidia card (forget the exact model at the moment) and as far as passing along DSP effects - it works fine for movies/music using J River Media Center and various VSTs. Effects applied in other software also pass along fine. Obviously if you get a sound card with built in DSP like CMSS-3D or the like, I'm not sure how you would get it to take effect on your video card's hdmi/audio out. I don't think it works that way :) Test driving a Xonar DG in the same box and I have to use one of its various audio outs to get the dolby headphone processing.

I guess you could say low Ohm (quality) headphones can be more picky.

yea I mention that because of the AKG K702's that I had, that gave me the amp run around and drove me up a wall. Trying to find a amp which they wasn't picky with that was a good match with them. that I could afford at the time.I fixed that problem by selling the K702 off and use the external amp I had at the time with the DT880 pro-250s.

Yes, getting enough current without making the volume too loud. Thing is though, if current = voltage/resistance (if I got that correct), and if the resistance is a constant (and resistance = the headphone's impedance), then... Is it actually possible to change the ratio of current to volume output? I dunno, I read a bunch of Wikipedia electrician stuff a day or two and it just made me more confused. How does current affect sound again?

I'm a long-time X-Fi Titanium HD/headphone gamer and I have a fairly simple non-gaming question to ask. I'm trying to get my headphones and X-Fi Titanium HD sound card properly set up for movie watching with PowerDVD, and noticed something seemingly unusual:

If I set my Windows 7 speaker configuration to 5.1 Surround and then run the speaker test, I can hear all 5.1 test sounds through my 2-channel stereo headphones (plugged into the headphone output on the rear of the sound card). Is this normal? Shouldn't I only be able to hear the front Right and Left channels? Could this mess up movie and game sound positioning?

Keep in mind that the CMSS-3D and THX TruStudio Pro Surround features are turned OFF in their respective operating modes. I want to ensure everything is setup correctly before I apply THX TruStudio Pro to virtualize PowerDVD's outputted surround sound.

It's supposed to be like that.
