Swiss manufacturer Soulutions have been in touch to tell Hifi Pig about their new 511 amplifier that will start production in October 2016 and will cost 24500CHF (around £17000). The 511 has the same switched-mode power supply found on the company’s 7 series products and is optimised for audio use.
The 511 can be used in three distinct modes:
Stereo-mode (150W @8Ohms, 300W @4Ohms and 600W at 2Ohms)
Dual-mode which gives the same results as above.
Mono-mode (600W @8Ohms, 1200W at 4Ohms and 2000W at 2Ohms)
The amplification circuit is similar to the 711 and 701 amps from Soulutions having at its core a proprietary voltage amplification stage that consists of linearized amplifiers operating up to a cutoff frequency of 80MHz. The Class A operation is supplemented by 500 000 µF of capacitance storage in the power supply
There are a total of 10 power supplies in the 511with those supplying audio and digital circuits being isolated from each other with optocouplers.
