I am thinking of buying a new receiver with integrated Dolby Headphone. I will primarily use a Sennheiser HD-595 for sound. Should I look for a receiver that has Dolby TrueHD decoding or would that not make any difference for Dolby Headphone?

The difference between lossy and lossless (TrueHD) is sound quality/fidelity. It won't make any difference to what Dolby Headphone is trying to do (externalize the sound).

I don't quite follow. When you say it won't make any difference, do you mean that a lossy soundtrack will sound as good as a lossless one when played back through DH?

No, I mean the difference between lossy and lossless has little to do with Dolby Headphone. For example: using a lossless track isn't suddenly going to give you better externalization than using its lossy counterpart. Instead, the differences you hear will have to do with sound quality, which will still be there with or without DH.

I think the question should be will dolby headphone even process the lossless track. Everything I've read says it won't.

Of course it will. Dolby Headphone already processes hi-rez lossless audio on DVD-A.

^Do you have personal experience with dolby headphone and HD audio/LPCM?

 

[metal112524]

If so what is your setup, if you don't mind me asking. I'm looking to get a SR4002 and the only thing holding me back is whether or not it will process the LPCM into Dolby headphone, source being the PS3 over HDMI. Any info is appreciated.

Marantz is a good choice. LPCM over dolby headphone will work according to my experience with the SR7002. It's fun and I use it for DVD movies and games. That said, you need to know that the Marantz line does not have the processing power to both decode HD, like TrueHD, in the reciever and implement Dolby Headphone. i think you said you'd use LPCM, so it should not be an issue.

The interesting thing is that i switched back and forth from LPCM and bitstream and discovered that while I enjoyed the frontal sound of speech with Dolby Head on, the bitstreamed stereo downmix actully trumped it. I heard seperation that was surprisingly good, and details were better. I don't remember feeling this way about non-HD over headphones, so I'm not sure what's going on here. It may be that i prefer bitstream to begin with (I do think it sounds better). But for LPCM dolby headphone should work just fine. I have Senns HD580, so I know where you're coming from. The Senns are really great for picking up the nuances of 3d sound, even when downmixed into stereo. The 595 is probably even better for movies. Only downside with the Marantz pairing is the Senns would prefer a brighter match. Not a big deal as I'm being picky. Anyway, i hope that helped.

I have one question. I watch movies on my laptop (unibody Macbook Pro under bootcamp with an external blu-ray player) and I've heard Dolby Headphone on a dvd before with the trial software and I have to say I really liked it. This is one of the reasons I'm thinking of purchasing poweredvd9.


My question is if I connect my headphones to my laptop will I get the benefits of trueHD like this? Basically, can a Macbook Pro with it's sound card pass HD sound through headphones? thanks.


Also, as far as I can tell Dolby Headphone is only 5.1 so a signal greater than 5.1 channels will be mixed down to 5.1 correct?

I am using a Harman Kardon AVR 254 and can confirm that Dolby Headphone works with LPCM up to 96kHz. The new Dolby and DTS formats also work as long as the use 48kHz.


Most Blu-ray movies are currently using 48kHz. There are a dozen or so titles that use 96kHz (mostly music). Only one title that I know of uses 192kHz (Akira). Most of this information can be verified at the following site:

I have compared the following two setups:


1. Panasonic BD-35 HDMI > AVR 254 > DH > Senn HD 595

2. Panasonic BD-35 optical (2-Ch PCM) > Headroom Portable Desktop Amp > Senn HD 595


For Blu-ray movies, I prefer the first setup. Dolby Headphone creates a 3-D sound stage that is very immersive.

Bumping an old thread here...


What about lossless Dolby Headphone over 7.1 analog? I was looking at the new Oppo BDP-83SE with those high-end DAC's.


Oppo 83SE -> 7.1 analog -> HKAVR254 ->Dolby HP implementation -> Phones


Would this result in lossless dolby hp?
