- Based on Purifi Eigentakt modules
- Stable to 2 Ohm (with less power)
- Powerful PSU of 3kW which reduces ripple and keeps the amplifier cooler
- Over 150W at 8 ohms (2 channels).
- Bridging option with more than 600W at 8 ohms (1 channel) and 900W in 4 Ohm with less than 0,0007% THD+N, making sure of distortion free sound at all levels
- Expectional low distortion, perfect linearity and the new class D modules minimizes intermodulation distortion compared to other designs
- A feedback solution that give expectional high damping factor of 13000 and 1400 all the way up to 20KHz (8 Ohm)
- Vera Audio input stage (buffer) with only the very best measurable parts
- No degrading potentiometers in the signal chain. A gain adjustment with 8-step rotary switches with gold contacts
- 0.004% precision resistor which helps to provide a CMRR (common mode rejection ratio) of at least 94dB at 1kHz
- Multi-step EMI filtering in the input stage to effectively keep harmful radio waves away from the audio circuit. In addition, the entire entrance stage is mounted inside a screen in a separate chamber inside the cabinet. There also extra shielded Neutrik XLR connectors
- Very low noise and high CMRR makes it even a perfect combination with horns or other high sensitive speakers
Functions and cabinet:
- Gain adjustment within 0.01 dB on both channels making it easy to match with different preamps/DACs or to incorporate to active speakers with amps to each driver
- A microcontroller monitors all the parameters of the Eigentakt modules and will warn with the LED in front of any overloads and temperatures. In the event of any faults that can damage the speakers, the amplifier will turn off in less than 200ms
- Auto standby function that automaically switches the amplifier to power saving mode mode after 3 hours of no signal. In standby mode the power consumption is only 0.25W and this function increases the life span of the amplifier. It can be turned off by using the trigger input
- Trigger input with LED light indicator
- Brushed aluminium chassis cut out from one block without any seams or visible screws
- Speaker terminals that accepts up to 6mm2 stranded wire, spades and banana plugs
- Selectable gain in very accurate 3dB steps from 12dB to 30dB as well as mute function
- CMRR of at least 89dB@100Hz and better than 94dB@1kHz (measured based on the IEC 60268-3 standard)
- Very low noise of less than 18uV
- S/N of more than 125dB (stereo)
- S/N of more than 128dB (bridged)
- 1 ohm capable

The calculations below show the power output vs impedance in bridged mode and in stereo mode. Take note that these are not measurements but they should be very close to actual performance.
