FYI, some Infos that I received from Stavros Danos, the Managing Director of Aries Cerat Ltd :
" The Kassandra II series comes in two models,the Mk2,and the Signature Limited edition.
The Mk2 is already in production and available, lead time is 8-9 weeks after receipt of order,and is 18.000 Euros retail.
The Signature LE will be available in Q4 ,2015,and is 55.000 Euros retail.
Both model's output stage can drive easily headphones down to 120ohms directly,but have no volume control.The analog volume control is an optional module,at 1500e extra cost and is a remote controlled hybrid shunt-ladder,discrete-resistor attenuator.
Power output for headphone use is 0.24W (6Vrms) for 150ohm cans,and 0.2W for 300ohm.
Further specification are:
Output impedance: >40ohm
SE output( true balanced as option ,no extra cost)
Digital inputs:
Customized.
Any combination of Optical,AES,s/pdif
Asynchronous ,low noise powered USB,galvanic isolated
Double local re-clocking of data and clock stream
Sampling rate: up to 24/384KHz( USB input)
DSD over PCM (with software plugin)
Frequency responce:
-3db at full output : 6Hz~100KHz
Distortions/noise:
-80db 2nd Harmonic at -40db output level
-110db 3rd Harmonic at -40db output level
-120dbr noise floor
Power consumption: 170W"
