I have never tried TacT, 2grand a piece is too much for me. I do however play my audio through AudioMulch, which does the same thing, no need to spend any money. That means my music\movies are stored on my pc. =\
I never heard of anything called ambiophonic speakers, u can use any type of speakers for ambiophonics. I used to have a massive sound barrier between my speakers, turning the living room into something horrible, until of course my girlfriend moved in =\. Though I would recommend it if u have enough space, the sound is simply better with a true barrier, and my speakers arent even that expensive.

I dont see why youd need a dvd player if u have a pc lol. As to blueray, you can download movies in full hd legally (and piratebay makes things even simple)
If u want ambiophonics and keep it simple, I say stick to a pc. Unless youre a real highend freak and use a record player, then i say use a real barrier. I still dont realize what the benefits from the TacT really are except that you can use it on a regular amplifier. I know RalphGlasgal personally, the guy who came up with all this ambiophonic stuff, and he doesnt really approve it either, let alone the price. (I think he is getting some money from TacT, and hes actually advertising TacT cooperation and its products on his website XDD)
Only real reason ull want the Tact is if you want to use your regular amplifier and no physical barrier.
You can call some speakers more suitable for ambiophonics and some less. Although it doesnt make a real difference, according to ralph glasgal horns are least suitable and electrostatics the best. I lov horns and horns is what I use and its perfectly in order just as it is. However speakers which are too big, will screw up your soundstage (think of the imperial horn). Low cutting your speakers at 100hz in whatever setup and letting a subwoofer take over is a grand idea seriously improving your bass. Bass is not localizable, so theres no reason to process it ambiophonically, ull only decrease the volume and the precision.
hope this helps

AudioMulch, i lov it. First time I used it was for ambiophonics. I started experimenting with it, fell in lov with it, and now, bit more than a year later im producing music on a regular basis =)
If anyones using it for pc and doesnt feel like paying 180dollars, feel free to contact me and enquire my serial number.

EDIT; dude, you dont need Vsts to run ambiophonics on AudioMulch. Google "audiomulch RACE" and ull find out how. ou need to know the basics of how the programm works though.
