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.

FEATURES

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.

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.

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.

The Singxer SU6 is superior in imaging, texture, bass definition, dynamics and detail.

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
