Description:

This amplifier design is based on Holographic - Cloning Amplifier Technology that is the foundation of H-Cat and is responsible for the remarkable undistorted realism this unit can convey. It has receieved raves from owners worlwide and can drive almost any speaker even though rated at a conservative 100wpc. This is a demo in house unit in perfect condition. This is an attempt to make the H-CAT™ amplifier method more understandable to the average audiophile reader and to clear up any misconceptions about the nature of H-CAT™. It has been difficult thus far to introduce a product so radically different in its operation to the audio industry. All I ask is that you be open-minded when it comes to learning about H-CAT™ and how it deals with amplification.
It has come to my attention that many audiophiles visiting my web site believe that H-CAT™ is using special circuitry to manipulate the audio signal and somehow generate the illusion of 3D imaging. This could not be farther from the truth. In fact it is just the opposite.

It is understandable that many would come to this conclusion because the only exposure of 3D type circuitry thus far has been introduced by designers who feel that they have the solution to dimension and space cues found in recorded material. They do not.

Several “holographic” products come to mind - all of which rely on the introduction of signals added to the original stereo channels to produce a phenomenon of dimension to the listener.

Here is text taken directly from literature on such a product…

“This is accomplished by sending a complex crosstalk signal from the left and right speakers in addition to the normal program. These extra signals are virtually identical to the unwanted second sound arrivals but they are out-of-phase with them and they cancel each other out. The result is a more three dimensional and wider soundstage, where the positioning clues are restored.”

This was a clever circuit arrangement that was designed to “overcome a problem in obtaining accurate sound reproduction”

Here are the facts as plain as possible:

H-CAT™ does not operate this way nor does it involve the use of opposite channel information or phase inversion or crosstalk or anything even remotely close to this.

H-CAT™ does not take any portion of the left channel information and introduced it into the right channel

H-CAT™ does not take any portion of the right channel information and introduced it into the left channel

H-CAT™ does not use any phase shift to create the illusion of dimension or space. Zero.

H-CAT™ does not use negative feed back (NFB) to remove distortion.

H-CAT™ channels are totally isolated from each other and are completely independent. H-CAT™ is 100% pure analog and has no sampling or digitizing or processing of any kind.

Up to this point there does not seem to be anything special or unique about a simple 2 channel amplifier circuit. Except for one thing – the H-CAT™ method of amplification – the circuit itself - is virtually distortion free and does not rely on conventional NFB to suppress harmonic distortion. This is a dealer demo that not left the listening room.
