Yes. One device that tried to stay in the market for a while under many names ended up in it's best form the Sennheiser DSP Pro headphone amp.
Dolby pro logic in a small package mainly for headphones.
I have one and love it. It is NOT a good high end headphone amp, but for Dolby pro logic or movie listening I am happy with it.
Most people don't know how to set it up or understand it, so it died on the marketplace. You can still find them on eBay sometimes. I won't get rid of mine.
Since I chose "high end" (on the cheaper side) audio for my main system, it meant really, I was not going to invest in "home theatre". But I do have a video rack (which I just rewired, UGH).
I do feed audio to my tv, which in turn feeds to my main system. But I got rid of my speaker based Dolby unit today, it was just not worth it. But I use my DSP Pro for ear blasting headphone movies in my system.
I was also called the "Lucas" for a while and a few other names. There is some stuff on the net for it.
It is NOT crossfeed. It is really five channel sound. Nifty little device.
You might even find a new cheaper variant of it sold new, but look for the DSP Pro.
