@viethluu Mea Culpa, Mea Culpa - I meant to reference @auroravengeance who stated
@arafiq the Aquarius is basically a clone of Denafrips Terminator. Musician is an original brand created by the company that develops and manufactures Denafrips stuff in China, that is why Musician and Denafrips’ stuff look nearly identical. Denafrips is just a brand created by a distributor company in Singapore.
Denafrips is much more than a brand. Their products as you agree are engineered at a higher level. The Aquarius uses Femto clocks the Terminator OCXO and the Terminator has separate power supplies for the digital and analog sections. I don't believe the parts in the Musician DAC's are better than Denafrips.
I had a Terminator and now a Terminator Plus with an Iris DDC. The Terminator prefers the I2S input.
FWIW the prices quoted by @soix are Singapore dollars the US equivalent are $6460 for the TP and $1790 for the GAIA, my Iris was $ 550. The Iris was less expensive than the Clock cables, less expensive than the power cord and less expensive than the HDMI cable I use with it. For me it fixed the gremlins with USB.
