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,

I am of the opinion that a really good pair of horn loaded speakers might be the only design out there that might do it all as well or better (though in a larger package) and could lure me off of the Ohms some day.

Good omnis (Bose are not, Ohms are only pseudo-omni techically) and horns (from what I've heard) probably share little in common other than the ability to truly disappear and provide the illusion that the players are right in your room.

The Ohms in particular also have outstanding dynamics though they do require a lot of clean power in comparison to horns.

HAve you heard the Ohms recently?
Mapman, what horns have you heard that are omni-like? I find that very surprising.

DC, I haven't heard any horns recently at all.

But I've heard murmurings that designs like the larger Avantgardes, for example, when properly set up, can totally vanish and present the illusion that the performers are in your room.

I tend to believe that it is true but haven't actually heard it with my own ears.

I can say for a fact that this does happen with the Ohms.

Horns and omnis like MBL or German Physiks and even the Ohms are clearly two ends of the spectrum in regards to design, but I'm thinking they can achieve similar effects in regards to holographic imaging through different means.
DC,

Horns would achieve their "life like" tendencies more via exceptional dynamics I would suppose than necessarily via "holography".

I have this vision that the exceptional dynamics of a very good horn system with just even average holography would be a stunning combination. I am not so certain though that any horn design would blaze the trail though in regards to pure "holography". Also, most horn designs that I see that I think might be able to cut it are too large for me to even consider putting into practice in my house.

Horns are one of those areas in audio that I have not experienced to-date very much, but it is an area that I do have a lot of interest in exploring someday in greater detail when the right opportunity presents itself.
Mapman, I owned the Avantgarde Duos and Trios. They do not disappear, in fact, unless you are quite far back from them they do not have integrated sound. Nor are they anywhere near as dynamic as the Altec VOTs with their compression drivers or the Klipschorns. I also had the now discontinued Beauhorns using Lowther drivers. They were dynamic and used a single driver, meaning they were blessedly free of a crossover. They also imaged quite well and mated well with the H-Cat electronics.

I do agree that a quick sound is essential to realism, but it is necessary not sufficient. My LaCampanellas are horns above 700 Hz and have four small and quick drivers below that.

I have once heard the MBLs sound okay and have been interested in their development for at least the last twenty years. They are omni only in the top frequencies and while open sounding are not at all holographic. German Physiks in my opinion are not worth discussing.

It has been many years since I heard Ohms.

I think until you hear the H-Cat line stage and amp, you will not have any idea what I am talking about.
