I am not good in writing a review of a Hi fi gear, still trying to paint a picture of this little wonder!!
Parasound ZDAC is a compact but full featured DAC small in size but weight 2.5 kg around I assume its because of its torodial transformer (Within a DAC exciting right??)
Currently its got connected with my Laptop 8 GB RAM with a Profigold USB Cable.
My laptop is optimized by a free software called Fidelizer on Extreme mode (Several internal services including Firewall have been closed by it,no problem for me as I use it only for Audio

) Media player is set on High priority mode and
It works IMHO!!
Currently I am using J River 18 with WASAPI Event style,its sound too good for my ear atleast.
My DAC is connected with Cambridge audio Azur 651a amp by Profigold Ultra performance stereo audio IC (pretty expensive for my wallet

) but it makes difference in my opinion.
Amplifier is connected with Mordaunt short Aviano 6 FS. CA 651a which has a inbuilt DAC 16/44. I think from that point to ZDAC is totally another Audio transformation story. Sound has become immaculately analytical and natural specially Bass has become really pronounced and tight.........some people said its clinical for me its not I think my MS 6 is on A warmer side and ZDAC just makes it more detailed.
Mid range has become much fluid with a lot of texture compared to in buit DAC of CA651a. Everything sounds totally new to my ear.I have to listen my entire collection once again Never thought about it!
Moreover its an huge improvement from my earlier set up.
Last but not the least all these thing happened because I have heard the advise of our FM Guru "BHAGWAN "
Thank you Bhagwan Sir for this wonderful piece of advise.You were absolutely right, I am not regretting at all!!!
