Dear Customer,

 

What  more  can  you  do  after  launching  the  Morpheus  one  of  the  best  dacs  available  today?  All  the  options  and  features  that  the  Morpheus 
already  had  but  now  on  steroids!    Introducing  Pasithea  by  Sonnet  Digital  Audio,  a  powerful  Digital  DAC/ 
comparable to others with a price tag whichis twice as high! The biggest difference between his predecessors 
based on a new generation of the previous used SDA-2 dac modules. This new SDA-3 module is able to run on a unusual high voltage
does this improve the signal to noise ratio but by working with four modules per channel a very low output impedance can be achieved.
the Morpheus, consumed energy is kept as low as possible and despite the eight SDA-3 modules used, the Pasithea consumes an average of 
16 Watts in full operation. As each SDA-3 module is using four R2R ladder networks in balanced mode, a total of 
involved to give the Pasithea top performance. Needless to say that we use Non Oversampling techniques. Our own designed and
DAC chips will guarantee a unique listening experience! The result of this process is an extremely high linearity, right down to 
gives the Pasithea a realistic 24 bit dynamic range. Due to new technology as used for the volume control, 
“variable”  or  “fixed  mode”.  As  a  result  the  Pasithea  can  be  used  as  a  digital  pre  amplifier  and  driving  power  amplifiers 
intervention of a normal pre amplifier or as a normal dac having a fixed output level.  Next the Pasithea is equipped with an expansion slot for 
DSP functions. If used the Pasithea will detect the module automatically.  

 

The  MQA  module  is  one  of  the  options  available.   MQA  (Master  Quality  Authenticated)  is  an  award
technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is 
small enough to stream or download. After MQA module is installed the Pasithea is able to play back MQA audio files 
and  streams,  delivering  the  sound  of  the  original  master  recording.  MQA  decoding  is  activated  by  default  in  the 
Pasithea menu so MQA

 

will be indicated on the display when played. 

 

The new approach of the Pasithea is a step forwards as it omits all electronics as used for a normal pre-amplifier. It is musical,
oversampling principle and simultaneously incorporating the technological progress  that has been made over the years while developing our 
products. 
 
We wish you many years of enjoyment experiencing music! 
 
You’re sincerely

Introduction

 

All  the  options  and  features  that  the  Morpheus 

DAC/  Pre  Amplifier  ,  a  product  that  is 

his predecessors  is the fact that the Pasithea is 

to run on a unusual high voltage. Not only 

modules per channel a very low output impedance can be achieved. As with 

3 modules used, the Pasithea consumes an average of 

a total of thirty-two  R2R ladders are 

Needless to say that we use Non Oversampling techniques. Our own designed and engineered 

emely high linearity, right down to -144 dB, which 

 the Pasithea can be used in both 

can  be  used  as  a  digital  pre  amplifier  and  driving  power  amplifiers  directly  without
