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?

Holography in my experience is only present in the best recordings....it is especially present in a live broadcast. It is dependent on speakers,amps, and cabling. Under the best conditions the speakers are transformed into perfect air pumps where the sound is effortless. Like coming out of thin air...everywhere and you are transported to the actual venue. I have experienced this with my Vac Renn Amp. Speaker placement,extremely clean power and a cabling synergy are needed I think to acheive this level but if it's not in the source it won't be produced.
Mapman, if it is true that "holographic imaging" is in fact "bloom", why do I hear this very often with tube amps and not with solid state? Either solid state or tube should be wrong then?

Chris
Some seem to think bloom may be one form of holographic imaging that is more associated with tubes, but I think only that not all holographic imaging is bloom. Holographic imaging can occur with or without tubes.

Honestly, I'm not sure exactly what bloom is. I've just heard people refer to it as adding some additional aspect of dimensionality to sound when present. Personally, I am somewhat ambivalent regarding bloom, though I do like the sound of good tube systems when I hear them.

Can you explain what you mean by either solid state or tube should be wrong then? I'm not sure I understand.
Mapman, what I mean is: if one way of reproducing music is different than the other, then either both ways are wrong or one way is the correct way.
Example a solid state amplifier has less bloom with a particular recording while the tube counterpart has plenty of bloom and harmonic richness --> which one speaks the truth?

Chris, you can't answer your question without hearing the original performance, which we seldom have the opportunity to do. This is one reason that attending a lot of classical performances develops a useful reference. This listening experience doesn't give you an ironglad judgement as to what's "right" and what's "artificial", but it does help.

I say that the very best tube and the very best SS are equally accurate. Added bloom or holigraphic effect are not part of the best systems. I'm talking about brands like ARC, BAT, Lamm, Rolwand, Boulder, Ayre, etc. They're very, very close, no matter what the owner of a particular unit may say. None "blows away" the others at this level.

When you hear an amp or pre that immediately strikes you as warm, extra rich, larger than real image, then some euphonic coloration has probably been added, usually on purpose by the designer. These systems attract a lot of followers and can give their owners much satisfaction.

If you don't get to hear a lot of live music, then try to hear a really great system with some of the brands that I mentioned. Take your favorite recording and see how it compares to what you're used to. There's more than one way to develop your references.
