Dolby Headphne with an amp

[freakydrew]

hypothetically speaking, if my soundcard supports Dolby Headphone (how many movies aside from Pearl Harbor actually use this?) will using an amp from my pc somehow mess with this technology?
I am looking at buying a Littel Dot II+++ with Beyers DT770 (250 ohm) and soundcard on order is Xonar HDAV deluxe.

thanks

I don't understand... any movie that is multichannel AC3/DTS can be used with Dolby Headphone.

sorry...I'll blame the Sunday afternoon gin and tonics for the unclear post.
Specifically, if my sound card has Dolby Headphone, will an external amp plugged in to my PC change the "magic" or will it be the exact same sound (with obvious amplification) as if my headphones were plugged directly into my PC.
This is still not very clear, sorry.

Ah, your asking will the Dolby headphones still be avialable when using a external amplifier.

That really depends. Most sound cards that have this setting will only have it avialable when your card is in headphone mode. When you switch to 2 channel mode that you would use to connect a external amplifier you would lose the setting as your not using headphone mode.

As long as we are not talking about a card with a internal amplifier then you shoudl be able to use your external amp with the card set for heapdhones mode.

I hope I am understanding your correctly and responded with what you needed.

Well, I use a Go-Vibe and movies sound fine. I wouldn't think an amp would affect Dolby Heapdhone unless it has a crossfeed filter.

I using DH1 on my Qinpu Q1 right now. aslong you have it set to headphones it should work just fine.

you are generally using the same input for stereo speakers or headphones on most soundcard. So no an external amp will not interferr with it. If you have an AV receiver which automatically enables the dolby headphone or in my case silent cinema then you will not get it by connecting an external amp to the analogue outs. I don´t know if there is a workaround for this I would be very interested. Since my headphones get all muddy on the AV receiver so I don´t benefit anything from using the surround feature.

There is such an adaptor, too. (JVC SU-DH1)
Surround Sound Headphone Adaptor - SU-DH1

Essentially, if I happen to find a movie with Dolby Headphone encoding I am almost better off to unplug from the amp and plug directly into the soundcard.
thanks for all thew advice.

Movies are not encoded with Dolby Headphone. The player software or soundcard can add the effect to the output.
The long and short of it is, aslong as your card doesn't have a built in headphone amplifier you can use a external amplifier and set the sound card for Dolby headphone.
You will have the Dolby headphone affect and your external amplifier.
Hope that makes sense.
