Holographic imaging


Hi folks, is the so called holographic imaging with many tube amplifiers an artifact? With solid state one only hears "holographic imaging" if that is in the recording, but with many tube amps you can hear it all the time. So solid state fails in this department? Or are those tube amps not telling the truth?

Just found this thread today. My first thoughts on reading through it are that this thread hilariously proves just how many different definitions there are out there for these terms that audiophiles like to use. The only way to be absolutely sure that we are speaking of the same thing would be to be in the same room listening together.

That said, I think atmasphere has done an excellent job of describing what most people mean by them, with the exception of bloom. I have never before now heard that term described as coming from distortion, though I have heard it described as "coloration," which I suppose could be reasonably argued is the same thing. However, I think both Detlof and Newbee have more accurately described the phenomenon of bloom, which does naturally occur, particularly in a good hall.

I would also agree that tubes and horn speakers are still the best way to hear this particular aspect of sound recreation, especially of an orchestra in a great concert hall. I would add, though, that the recording engineers and their mike placements and mixes have a huge, not to be underestimated effect on this. I have been a part of many live orchestral performances that sounded amazing only to listen later to a recording made by a well-meaning engineer who got it amazingly wrong. And if that happens, which it does far more often than not nowadays (not to start this argument over again, but digital recording has a very great deal to do with it), even the very best system out there, no matter what type it is, can't fix that. If I had a penny for every audiophile who lost faith in a system or component when the actual fault lay with a poor recording.....
TBg,

Believe me I'm not interested in arguing either, but realize that the definition I provided is not mine, I'm just sharing it. Take it for whatever its worth.

I'm just trying to help provide some clarity in terminology where it exists so as to help cut to the chase rather than argue what certain words mean.

Personally I learned from it that Carver holography really isn't holography at all. Its just one engineers approach to providing a bigger sound stage with improved 3-d imaging if that is to someones tastes. Obviously, its not to many, at least via the means provided.
The best holographic imaging I've experienced is through a Vac Avatar driving B&W speakers. There's something about cone based speakers and tubes that deliver a full sonic image that literally dances in front of you. I'm not sure I would always contribute holographic imaging to good sound staging though. It seems you can get a realistic, pin point sound stage but not necessarily have it be 3D if that makes any sense. Overall tubes tend to solidify stereo images better than solid state but I wouldn't say it's an absolute. I've heard some pretty good almost 3d imaging from a solid state amp but with a tube-pre. Room acoustics also play a big part along with the low level detail that others have brought up.
Learsfool,
stupid of me, I should have thought of adding horns to the list of speakers which do best in the fields which are being discussed here. Thanks for reminding us. Thanks also for pointing out once more the importance of the recording engineers and their miking and mixing techniques. I often wish, Mohr and Layton were still around.......
Hcat apparently sounds interesting to the untrained ear.

Let the guy go; he's championed other suspect products as well. Most of them flavor of the month products like this one.
