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?

Tbg,

You indicate you've heard MBL.

Have you ever heard Ohm or German Physiks?

I understand and appreciate that you do not lean towards the omni sound from ehat you have heard.

Personally I have heard Ohms only and like the wide range, wide/omni dispersion, highly coherent Walsh driver approach in general.

MBL uses multiple drivers in the Radialstrahler designs as I understand it to achieve omnidirectionality within a particular frequency range.

I am not a fan of designs that attempt to integrate many drivers in general, omni or otherwise, because believe it is difficult or near impossible to do well. maybe MBL does it better than most...I don't know.

If you have not heard an Ohm or GP design in particular, try to keep an open mind. I wouldn't equate all onmi designs equally any more than I would any other category of speaker design.
My impression is that my equipment is much more "holographic" than what I hear in live music (jazz, chamber), and live music is much more dynamic than what I can get out of my system.

On the "holography" side I find that good SS (Pass XA30.5 for example) is very good on locating the instruments within the soundstage with depth and stable localization, but that tubes make the individual instruments sound more 3D as a source, the instruments themselves seem more 3D within the soundstage to me with tubes than SS. I don't know which is a more "distorted" signal, but that has been my experience pretty consistently with the same speakers and room placement.
Pubul57,
I think that your observation holds good for most of our rigs, at least I made the same observation, when I had the chance to compare the WAVAC phono pre, which is tube with the Boulder 2008 phono pre, which is solid state. The Boulder threw an impressive sound stage with the highest rate of transparency I had ever heard, whereas the WAVAC gave individual instuments and voices a degree of air and bloom which came closer to the real thing than I had ever heard before. Wished one could have both.
