 Vortex Filter
Amp to Loudspeaker Modules

The Vortex Filter represents a new and innovative solution engineered to reclaim an area of audio system performance that heretofore has been shrouded in mystery and seldom (if ever) addressed within most engineering circles. As a result, no other conventional audio cable or accessory alone can achieve the sonic benefits commonly experienced by the inclusion of Vortex Filters in your cherished audio playback system. Typically, users can expect the following:

  • An elimination of “electronic fog” or “haze” and/or the effect of a “veil” having been lifted from the system
  • Significantly increased levels of micro-detail and resolution
  • A richer, more palpable rendering of delicate harmonic texture, naturalness and overall realism
  • Improved bass definition, speed and authority
  • Improved sound stage width, height & depth
  • More succinct imaging and instrument localization

The Ultimate Value Series Vortex Filter

The UVS Vortex Filter Amplifier-to-Loudspeaker Module is a value-optimized device constructed with quality components and is particularly convenient for use in multi-channel systems. It is a totally passive (no batteries or other power sources required), dual-channel unit (only one unit required for stereo operation) that is simply inserted into the signal chain between the amplifier and loudspeaker.

Specifically, the UVS-VF is designed to address a heretofore neglected class of Phase-related Distortion that arises within the amplifier/cable/loudspeaker section of any high fidelity audio system.  For effective treatment of two audio channels each UVS-VF is constructed with two totally separate and isolated “Smith Cell” sections, one per Input/Output channel.

The UVS-VF can be ordered in stock form as shown in the above photograph, or or it can be custom-built to your individual requirement, including your choice of Binding Posts and alternative end plates in the form of “L Brackets” for mounting the module to any horizontal or vertical surface you wish, such as a wall or the back of your loudspeakers.

The Smith Cell:

The Smith Cell was developed to address very unique and obscure forms of distortion artifacts that typically manifest, to one degree or another, in even the most pristine of audio systems.  In fact, this area of system performance is a matter of much debate in the audio world, and there are many that have not understood and/or recognized its existence.  These forms of distortion are rooted in two primary areas within the audio system:

  • The microscopic realm of electron interaction with the very atomic and molecular framework of conducting metals and materials.
  • The complex secondary effects that occur within circuit components and conductors upon their exposure to electrical AC voltages and currents.

    To be succinct, the proper terminology regarding item #1 above is that of the"Phonon" behavior within conductors, and how such phonons interact with electrical current as it flows through the conductor.  Phonons are defined as "virtual" particles and can take the form of a single atom, molecule or groups thereof, or a single crystal (termed "Brillion Zone") or group of crystals.  Even impurities in metals or other materials can be viewed as phonons.  One will note that it is via successive phonon energy transfer that thermal energy conducts and mechanical vibrations transmit through a solid material

    While the subject is too deep to adequately cover in this article, just as one example we would make note that phonon behavior is commonly believed to be one of the primary sources of "Flicker noise" observed in electrical systems, and is also known as "Pink noise" (1/f noise) that is observed in biological systems, Gravitational Wave Astronomy  and throughout the physical universe.


    The only real question is one of its audibility with respect to phonon activity.  As far as its "standard" form is concerned, observed as the noise produced by common resistors and other components, it is well-known and must be considered in low-noise amplifier design. So at least on one level we know that it is audible.

    Going beyond that though, it is our contention that said phonon behavior and its interaction with and subsequent modulation of electron current flow, it also manifests as a form of "Phase-Noise/Distortion" and as such represents a more subtle source of phase-related error artifacts in audio systems. Consequently, we also suspect it has been stealthily operating behind the scenes of the audiophile cable debate all along.

    Regardless of their source though, all forms of Phase-Noise/Distortion impart a sonic effect analogous to that of a video camera that is "ever so slightly" out of focus, such that fine musical details and subtle harmonic timbres become slightly blurred and less well-defined.  For further reading and in-depth analysis of the subject, please review our white paper:

     

    There is also a type of “Active Phase-Noise/Distortion” at work in all systems, and the URS-VF was designed to address it as well. For further details regarding it’s source we would refer you to the following section of this website:


    I
    n order to significantly reduce (if not totally eliminate) these two forms of phase-related distortion, we have developed the "Smith Cell."  It relies on a very unique application of materials in a configuration that prevents signal current flow from directly interacting with them, while at the same time allowing these same materials to strip away both active and passive forms of Phase-Noise/Distortion at the sub-atomic level. System performance gains are manifest from the deepest bass up into the higher mid-range frequencies, with typical observations being that of deeper and tighter bass, increased tonal accuracy and realism, greater micro-dynamic resolution, a wider and deeper sound stage, and improved image localization.

     Another observation many have made is that system performance is no longer as highly dependent on the quality (read: expense) of the speaker cable formulation being used.  We as well as others have found that with the UVS-VF inserted in the system, more common and lower cost cables provide nearly the same level of performance as their costlier and more exotic counterparts.  It has even been reported that common "lamp cord" provides very sufficient performance when used along with the UVS-VFs. 

    In fact, it has been claimed that a system employing the UVS-VF and lamp cord for speaker cabling usually sounds better than the same system using exotic cables but with no UVS-VF installed.  This all makes a certain amount of sense when one considers that the very action of the Smith Cell is to ameliorate the effects of phonon induced Phase-Noise/Distortion, which is most likely one of the many factors differentiating one cable type from another.  If one eliminates the fundamental distortion artifacts that given types of similar system components induce, then one also eliminates the primary difference between those different components.

    Construction:

    The UVS-VFs are constructed of quality materials including OFC Copper Conductors and Gold-plated Binding Posts for both Input and Output connections.

    Use:

    Seeing that the UVS-VFs are totally passive devices, no forms of external power or batteries are required for their operation.  Installation is therefore a simple matter of inserting them either at the speaker end of your existing speaker cables and then using a short piece of "jumper" wire to connect their output to your loudspeakers, or the reverse by placing them at the amplifier end of the speaker cables and using a jumper to connect them to the amplifier. 

    As stated above, we have found that the quality of the jumper wire is not particularly critical. Therefore, we provide a 1-meter pair of standard OFC copper cables terminated with Spade Connectors at each end.  If you prefer, (at additional cost) custom jumpers of specified length can be provided that are constructed of other materials of your choice, such as Ribbon-foil or Litz Wire conductors, Banana Plugs instead of spades, etc.

    Finally, the best way to determine just how much improvement the UVS-VFs provide is to place them in your system and listen for at least 20 hours over an extended period of time.  If possible, allow them to "burn-in" for at least 24 hours before your initial evaluation.  You may or may not observe a significant effect at first, but continue to listen for the better part of two weeks.  Then to find out just how much difference they are truly making, simply remove them from the system and listen again.  As many find, you will likely be a bit amazed just how much you miss them and will want to return them to the system immediately.

    Happy Listening!
