It's BAAAaaack!

At least this time it's really expensive, (and digital) so it's bound to get good reviews.

    Oddly enough, you can get 3D imaging with good speakers.

    BACCH has been around for quite a while. Kinda like controlled nuclear fusion. ;)
    Indeed, it's even been discussed here before (thread started in 2015).

    My Carver CT-23 preamp has the Sonic button. I tried it in the 90s and wasn’t impressed. Haven’t used it since.

    ... and, don't forget, cats & kittens, at the other end of the spectrum, there's Schiit.

    It's basically David Hafler's "Dynaquad" ambience recovery scheme in an expensive package (albeit with some other... umm... Schiit thrown in on top, like jimmies on the sundae).

    My C16 also has Sonic Holography, I was not impressed either. No matter how I had my speakers set up all it seem to do was recess the vocals back deeper into the music.

    I had my speakers set up exactly like it recommend in the owners manual.

    Fail.

    Dynaquad requires at least three speakers, the diagram shows four. Another iteration has a front-center channel in addition to the rear speaker(s). It's a poor-man's "surround sound". The basic premise is Left channel, Right channel, (to provide "normal" stereo) then add L + R for the front center, and L - R and/or R - L for the rear "ambience" speaker(s). Add in a volume control or two, or three, and some switching. Some folks like it, some don't. I find it very listenable, dirt-cheap and completely unsophisticated compared to the various and increasingly-silly/complex Dolby and DTS multichannel schemes. But then, I'd rather listen to ONE "quality" speaker (two, preferably) than eleven or fourteen or thirty-nine-point-six bottom-feeder speakers including a multitude of "sub" woofers which in reality aren't even proper woofers let alone "sub-woofers", scattered semi-randomly and invisibly around the room.

    Crosstalk-cancellation is a whole 'nother thing, unrelated to "surround sound" although somewhat compatible with surround-sound. The Bacch gadget...and Carver's...and Polk's SDA, uses two speaker cabinets. I guess a person could argue that the SDA drivers kinda-sorta represent a speaker-within-a-speaker ("four" cabinets); but I don't think most folks would.

    My friend has carver sonic holography, he's tried it every which way, and said it worked best believe it or not with the speakers right next to each other.

    Well I can say I definitely didn't try that!

    I thought it kinda strange, but he claims it works, although I didn't ask him what speakers he was using he has many to choose from.

    A trip to your local weed store might provide the holographic images one seeks!

    Just to let you know I heard this today at Axpona. This is nothing like Sonic Holography. What this did was truly amazing. I heard birds and flies flying around my head that it actually made you think they were in the room with you, 100% realistic. When the music came on once again super realistic. Uncanny how realistic it made the instruments sound. Only problem it was just a tiny area this worked in, BUT that area was insanely super realistic!
