Thank you for your mail.
I could connect and play the USB SPDIF. !!!!
I am impressed, Amazing sound.
I am a fan of analog sound and this is nearest to analog I heard.
Beautiful music I cannot believe its the same CD sound so good.
I feel you are a master about sound and a genius.
I am very much interested to hear your other DACs,
Currently I am using a Audio Note KIts (ANK) kit I assembled DAC 4.1 from Brian Smith , CANADA. It has AD1865 chip.
I am reaaly happy with the USB SPDIF , I have almost tried 20 USB to SPDIF convertors from Art Veloce, Teralink X2 and many others….
