Three-In-One Tube Buffer, Bass Control, and Sound-Stage Expander Fixes Flatness, Focus, and Glare: Jolida Foz SS-X Works Great with Vinyl, Is a One-Stop Solution to Common Audio Problems

A three-in-one tube buffer, bass control, and soundstage expander, the tube-driven Jolida Foz SS-X adds warmth to your system and allows you to experiment to your heart's content with low-end responsiveness and staging dimensionality. Designed by engineering guru Jim Fosgate, it's most affordable – and fun – solution to flatness, focus, and glare available. Just place Foz SS-X between your source and amplifier. You'll be shocked at what it does. It works great with vinyl. And Foz SS-X can even be used to test the phase of a recording or your entire system. The unit's logic display gives you visual confirmation of your system's phasing.

Foz SS-X serves as an effective, efficient, and low-cost solution to common audio problems that have long lacked a simple, one-stop fix. If any of the following issues sound familiar – Two-dimensional sound in your stereo system? Want your speakers to disappear while playing? Getting flat sound from your soundbar? Lacking bass in your bookshelf speakers? Hearing too much edginess from high notes? Need some more space and dimensionality in your headphones? Too much boom in your speakers? Does your gaming lack excitement? – you need Foz SS-X.

Having spent decades designing, building, and auditioning every possible circuit approach to tube amplifiers, preamplifiers, phono preamplifiers, and other accessories as well as collaborating with Ray Dolby in the groundbreaking development of surround sound, Fosgate made Foz SS-X for every kind of listener. The SS-X circuit functions as a single stage between your source and amplifier and can improve the performance of your audio system with tube buffering to clip the edge off highs, add or reduce your bass, and focus or expand the three-dimensionality of your soundstage.

Sound too good to be true? It isn't. Try one in your system today with the security of our 100% Satisfaction Guarantee.

Single-Loop Design Features Three Major Components
SS-X's single-loop design has three major design components. Initially, the signal passes thru the tube which buffers and cleans the signal. Then, the bass equalizer circuit is designed to increase up to 9dB low-bass impact without bass boom. Conversely, in the event of boomy bass, the bass equalizer can reduce the boom up to 9dB. Finally, the dimensionality circuit adds a greater sense of depth and space while helping pull the soundstage outside of your head. Part of a Jim Fosgate US patent originally used in surround processors, it cross-feeds signals between the channels so each channel has a signal from the other which is out of phase. Negative feedback is applied around this stage in a single loop. Output offset gets controlled with DC servos, allowing the video buffers to directly drive the signal path with no output capacitors. Only one coupling capacitor exists per channel in the signal path – and it is enclosed within the feedback loop, eliminating capacitor colorations. Separate, oversized storage capacitors are utilized on each channel to provide solid supply voltage without voltage regulators to affect the signal. The circuit is configured so that audio signals from the one channel cannot couple to the other, preserving soundstage width and depth.

Incredible Technical Specifications
SS-X's distortion and noise levels are below the threshold of hearing. The very wide bandwidth permits audio signals to pass through without coloration. Bandwidth is an amazing "ten times" the threshold of human hearing: 2Hz to 200KHz at -3dB.
