Swissonor RS Solid State Amplifier

"RADICALLY SIMPLE"

solid state ... mais tres tres tube !

SWISSONOR   RS Solid State Integrated Amplifier

RS=Radically Simple 

 

If you need more power to drive medium efficiency loudspeakers, without giving up the radical fidelity of Swissonor tube amps, this item is for you. The strictly double monophonic design using two huge toroidal transformers enhances an ultra sober design, composed of a passive line preamplifier and a single chip OPA per channel, wthout any intermediate stage.

 

The optional phono preamplifier module with passive RIAA equalisation allows it's use in a high end vinyl disc music system. The rugged construction on a cast iron mainframe with decoupling elements translates the Swissonor philosophy into the universe of solid state technology:

 

  • Shortest signal path, connectors and cables used for connecting separate components are eliminated

  • Design eliminates impedance and gain mismatch and reduces the number of active circuits

  • One oversized power supply for each channel

  • Separate ground wiring together with central ground connection and ground lift for best signal purity and lowest hum and noise

  • Passive line amplifier followed by a single 3886 OPA power amplifier per channel

  • High quality components all around, as Block toroidal transformers, very long life low inductance capacitors, ALPS blue velvet volume control and double layer gold plated cardboards.

"LE QUARANTE-CINQ"

Swiss Zen

SWISSONOR   TYPE 45 SE  Integrated Amplifier

This is the version of the classic V.S.O.P. integrated amplifier using 45 triodes in Single Ended configuration. The back-to-the-roots concept brings the most musical sound possible to very high efficiency loudspeakers  -- minimum 96 dB Thiele Half Space Reference Efficiency.


Optional OP Phono amplifier in passive RIAA design, or optional Digital to Analog Converter (DAC) make it really versatile.
 

As a high performance Swiss Made unit, the Type 45 SE's circuit is three-dimensionally decoupled on a cast iron base frame using the same receipts as its benchmark, the AM series:
 

Shortest signal path, connectors and cables used for connecting separate components are eliminated. Design eliminates impedance and gain mismatch and reduces the number of active circuits. Separate power transformers for tube and solid state sections Separate ground wiring together with central ground connection and ground lift for best signal purity and lowest hum and noise.
 

Preamp-driver with a bootstrap of 12AT7/6201 triodes, power amplifier with Full Music 45/n Mesh Plate triodes. Without negative feedback loop.
