BATTERY POWERED
The power system design was optimized and the audio section was powered by a 7.5F (7.5 million uf) supercapacitor. While in operation the SU6 is charged by an adapter (included). The SU6 internally is powered by the super capacitor to ensure clearest sound reproduction.
CLOCK SYSTEM
Built-in CPLD pre-shaping technology, FPGA-based source synchronization technology re-shaping the isolated I2S signal, thus eliminating the additive jitter caused by the isolation chip. The newly designed FPGA algorithm, built-in FIFO buffers the data and then outputs, SPDIF output is re-encoded by FPGA, so that the coaxial output can support PCM 384K and DSD DOP128 at the highest. Using CRYSTEK’s CCHD-957 high-performance femtosecond crystal oscillator, with the self-developed constant temperature system and ultra-low noise super capacitor power supply system, further improve the short-stability performance of the clock.
Original single clock system, all circuits of the whole machine adopt synchronous clock design, in which USB clock is synthesized by PLL derived from femtosecond clock.

- USB input socket is a standard USB-B type female socket, USB power supply range is 4.5V-5.1V;
- BNC interface and RCA interface output standard S / PDI signal, the level is 550mV
- XLR interface output standard AES / EBU signal, the level is 3.3V
- The word clock (WCLK) output uses BNC interface, the level is TTL (no load), the output impedance is 75 ohms
- DC POWER input socket uses DC2.1 socket to support 7.5V-9V DC input (in order to realize the fast charging of super capacitor).

I am very happy with the sound. The first hours it wasn’t very impressive but now the sound has improved a lot. After 150 hours the SU6 started to shine!

The Singxer SU6 is proving to be a major improvement in my system. Delightful!

First, outstanding customer service from Jos. I was sent the wrong item and he took care of the issue immediately. Now on to the review.
I had been using my Gustard R26 connected to my pc with a wired internet connection. When I received the SU-6, I connected the pc via USB and the R26 with IIS. The sound was better, but not by much. My initial impression was I paid HOW much for this? I told Jos I was not impressed with the SU-6 and he told me to wait. A couple of weeks later I turned my preamp and amp off but forgot to turn off my PC and left roon running overnight. When I turned my preamp and amp back on the next day, I was stunned. The sound had completely changed. There was more clarity in the music, more depth, and a bigger soundstage. I now have about 80 hours of use and the sound has improved further. I was told the sound will reach it’s peak improvement after about 300 hours. The SU-6 makes the journey to get there fun and enjoyable. I highly recommend it, it’s well worth the price. Just be sure to give it time to reach it’s full potential.

Seems to work well with my Wireworld Silver Sphere HDMI cable and my Holo May KTE.
My whole system sounds ‘right’ now in a way I’ve never heard before. It’s a feeling that’s similar across all input formats and musical genres. Excellent soundstage, neutral frequency response, realistic timbre, excellent micro detail, good low end drive and the blackest of black backgrounds.

The Singxer su6 tagled your equipment up to a much higher level. Especially if you’re playing with a Nucleus, Nuc or Rhein z1 you certainly have to meet this sensational SU6 . Stronly recommended i’ve you like timing; rythm and refined heights. I’ts you’re number One choice.

Had a great listening evening yesterday. To be honest, the sound with the Singxer SU-6 (coming from my Vortexbox Audioserver premium xl) is breath taking. I am really surprised how it works that way and why others are (probably) do not include this technology …. in addition, I have tried several components and settings, nothing works like the singxer …. Great weekend! Michael

Very pleased with the SU6! It has a silky and refined heights, great details and controlled bass with the right amount of tightness. Midrange is rich and very nice textured.
Mike (geverifieerde eigenaar) –
Have been enjoying the Singxer SU6 for about one month now and am very happy with the sound.
Am still in the “running in” phase but even now the system is sounding both more musical & much more richly detailed.
Sjoerd (geverifieerde eigenaar) –
Thanks! Sounds a lot nicer indeed! Wow! Thank you for your advice, very happy.

After ordering, delivery was fast, because it was on stock. My MicroRendo has USB out and I needed a converter, which has data simultaneously available in AES, SPDIF (RCA and optical), I2S (HDMI, RJ45) format. Instead of the included PSU, I powered it with a SBooster 9V lineair power supply and the USB port with a SBooster 5V lineair power supply. I use two DACs simultaneously, a Sabre DAC for the loudspeakers, a NOS DAC for the headphone. This is the best sound, I can get with my DAC’s, even Spotify sounds like near_CD quality. This is a DDC and just a link in your whole equipment chain, so the final sound depends on the rest of your installation. But as they say “garbage in, garbage out”, the source quality is the start of the chain.
Fred –
The Singxer SU6 is superior in imaging, texture, bass definition, dynamics and detail.
Christophe Adam –
WoW – I am really impressed !
Much better sound with Singxer SU6. Even though it has been already great now it is really better. I am happy!
Many thanks
Adam
