For the past 15 years, Vinnie Rossi (initially forming Red Wine Audio in 2004) has established an enviable reputation for unique audio circuit designs, top quality hand-built production in the USA and sterling customer service.
Professional writers and end-users alike have reviewed his creations in print and online only to overlap by extolling their exceptional performance, superior value and considerate options that allow customers to buy what they need rather than face fully loaded production builds by default.
Fast-forwarding to the second half of 2018, Vinnie Rossi introduced his finest components to date, the L2 Signature Preamplifier and Monoblocks. By mid-2019, multiple L2 reviews confirmed that now the brand had begun to favorably compete against esoteric ‘cost-no-object’ challengers from all around the globe, yet still maintains its forward-thinking high-value roots. One reviewer even asked why none of the larger and more established tube electronics manufacturers had not managed to design such an uncompromising and purist design as the direct-heated triode L2 Signature Preamplifier.
For Vinnie Rossi, approaching premium two-channel audio design from a fresh perspective is at the core of his ethos. In an industry flooded with the same old design topologies that have been circulating around for decades, he chooses to demonstrate his genuine passion for his craft with innovation.

Reference D/A converter with integrated preamp
Proprietary signal conditioning circuits
Discrete I-U stage; allowing the implementation of the state of the art requirements of the DAC chip. Almost all manufacturers rely on ready-made op (operational amplifier) solutions; unfortunately, there is not a single component on the world market that is good enough. In SATIE, therefore, the consistent pursuit of a discrete stage with impressive performance data and sound quality is pursued.
Flag ship ESS Technology DAC chip
Digital to analogue conversion is carried out by the ES9038PRO Sabre chip, regarded as one of the finest silicon implementations in the industry. This chip incorporates innovative circuits delivering spectacular music free from annoying artefacts. 4x balanced 32-bit D/A converter per channel pass over audio to our proprietary discrete analogue circuits. The femto master clock with a clock accuracy of under 0.1ps clock jitter makes this approach feasible.
Analogue volume control / preamp functionality
SATIE uses a highly sophisticated log. ladder network controlled by gold contact relays forming a constant impedance passive attenuator. This architecture achieves the advantages of an active buffer stage without, however, having to accept the disadvantages of additional noise and distortion. By using this outstanding preamp functionality for an external analogue signal (e.g. phono stage) will make SATIE the last preamp you will ever need.
Digital filter with selectable characteristic
The user may select any from 6 filter options on the fly. Besides a standard PCM, high stop band rejection FIR filter giving the best performance on the bench, there are several other options to choose from.
3x Femto master clocks with TJ < 0,0000000000001s
SATIE employs 3 high performance clocks, one for 44.1kHz frequency group, one for the 48kHz frequency group and the third for the reclocking data buffer.
Reference Stereo Power Amplifier
Strictly balanced architecture
The WIDOR features a completely balanced architecture, with no back and forth conversion. In consequence, two identical amplifiers are employed, one driving the speaker+ and one driving the speaker- terminal. While this doubles costs, it relieves the circuit ground from carrying the speaker return currents, resulting in a clean and unspoilt ground potential.
Ultra wideband design
The high quiescent current design of the preamp and driver stages enables a core speed close to 1.5MHz, slowed down only by input and output filtering to match real word requirements. With filters in place, the small signal as well as full power bandwidth (!) measures an impressive 500 kHz. The lower frequency limit is around 0.3 Hz. No coupling capacitors are used throughout.
Inherently low noise
High resolution audio is intrinsically tied to low noise and low distortion. System noise is the lower resolution limit of an analog system, because it determines the smallest signal not masked by a noise floor. Hence, low noise levels and thus a wide dynamic range are desirable. A-weighted output noise measures 20µV for the WIDOR giving a SNR of 126dB or an equivalent to 21 bit !
Regulated power supply
Every section of the WIDOR amplifier is powered by high speed and low noise linear-voltage-regulators. Even the high current drawing MOSFET output stage is supplied by a tightly regulated supply with an instantaneous current capability of +/- 50A. Ripple and noise free supply rails are essential for the low noise operation of the whole amplifier. It further helps to reduce distortion and improves damping factor.
Lateral MOSFET output stage
The lateral MOSFET transistor originally developed by Hitachi in the late 70’s is probably the only semiconductor power device solely made for audio use. Famous for its tube like characteristic and perfect bias stability under any load conditions, the WIDOR uses a two pairs of tandem devices in each output stage. The H-bridge output transistor array is energized by a heavy duty toroidal transformer running a bank of 480.000µF storage capacitors.

Based on the resources of one of high end‘s most distinguished design companies, the Swiss cables product range offers truly innovative technical design and sonic merits at a groundbreaking price-performance level, manufactured to the highest standards in Switzerland.
Swisscables - signal- and power-products - incorporate latest generation metallurgy, application specific, field-optimizing conductor geometry, premium connectors and novel micro distortion-free insulation technologies whose sonic benefits cannot be achieved with the materials employed in the majority of high end cables available today, whatever their price. Made in Switzerland in conformity with modern eco-standards.
The success we achieved so far with Swiss cables is thanks to the following facts:
- We use only first-grade materials and all our cables are fully handmade in Switzerland
- Swisscables have all UP OCC solid core conductors of special copper alloy
- We wrap the wire in a light natural fibre which weights approximately 2 g per meter
- The implemented geometry is adapted to the required length of the cable
- The wire network is introduced into a flexible tube and around this natural bre is solely air (air-dielectric!)
- We use wood as resonator for our connectors
Characteristic features of the different ranges are the dimensions with the corresponding geometry and the different connectors which lead to more energy and let you experience the soundstage again more intensively.
