Mechanical strength has been a hallmark of Perreaux products since the company first started production back in 1974. The concept behind the physical design and construction is that each structural member should contribute to both rigidity and performance.

The SM6 is a truly balanced preamplifier, from input to output. The positive and negative halves of the signal never touch, remaining balanced throughout all stages. This circuit topology offers the ultimate in performance, providing increased noise rejection and lower levels of distortion.

Four discrete output stages operating in Class A provide output buffering. This enables low impedance loads to be driven, over long cable lengths using any cable.

There is a separate power supply for each section of the preamplifier. One for each of the volume control chips (two chips are used to keep the system fully balanced and therefore, to maintain separation, each chip is supplied with it’s own separate power supply), another one for each of the output buffering stages (once again because the SM6 utilises a fully balanced circuit topology), another for the digital logic and the final power supply looks after the input relays. The advantage of this is that there is complete isolation from stage to stage. The digital noise is kept completely out. This is further evidence of a thoroughly designed product offering.

Many audiophile grade components are still provided with analogue controls that are adjusted on the faceplate of the unit. The SM6 features an infrared (IR) remote control meaning you don’t have to get out of your chair to make an adjustment. Some of the functions available are: standby, mute, volume up/down, display on/off, input select and balance.

Perreaux engineers pay particular attention to designing the product to ensure maximum separation between internal signal and power earths, only meeting at a central starred point.

The SM6 uses two digitally controlled resistor ladder volume controls. This is because we treat the positive and negative parts of the signal separately (true balanced topology). The advantages of using a digitally controlled analogue resistor ladder to adjust volume are precise control, no contacts to corrode creating wiper noise and no analogue component drift.

You do not need to purchase an RCA style splitter if you want to drive two separate power amps simultaneously, as there are dual parallel preamplifier outputs.
