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 Reference Series Vortex Filter
The URS Vortex Filter Amplifier-to-Loudspeaker Module is a full-featured device constructed with the best components available. It is a totally passive (no batteries or other power sources required), monaural unit (two units required for stereo operation) that is simply inserted into the signal chain between a given amplifier output channel and its associated loudspeaker. An additional feature that is unique to the URS-VF alone is a user adjustable switch that allows its Zobel Network feature to be configured for achieving the best possible match between your amplifier and loudspeakers.
Specifically, the URS-VF was developed to address the Phase-related and Back-EMF induced distortion artifacts that arise within the amplifier/cable/loudspeaker section of any high fidelity audio system. Within the Vortex Filter are separate “Smith Cell” & “Zobel Network” sections that have been specifically designed to individually address each of these unique classes of distortion.The URS-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, Binding Post locations (e.g. Inputs and Outputs both on one side), and even 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.
