This is a NEW Singxer F1 w/aluminum case that is for sale together as a package. It’s NEW condition with no hours of use.Pre-assembled. Manufacturer recommends 500hours of burn in time before you evaluate it’s final sound. Our customers say it will sound Bright when during the initial burn in. The same goes for the Singxer SU-1, a common trait with the Crystek 575 clocks. Personally,I don’t bother listening to it at all until after the break in is finished. I turn on my system and let it run for about 2 weeks straight. This will take the edge off and will relax into it’s final sound.

We want to be upfront and honest to set your expectations before purchasing. Most DDC’s we have owned will have burn in times that are required.

F-1 digital interface module, the whole network starting. The first use of the second generation XMOS chip developed high-XU208 USB interface, support firmware upgrade. Self-developed schematics and firmware (including XMOS and CPLD), non-reference design.

The reason why Singxer F-1 is so great is that it primarily uses some of the following TECHNOLOGY:

1. full isolation technology, 150Mbps full-chip isolation, interference can be completely isolated from the PC;

2. source synchronous shaping technology and CPLD technology, I2S signal isolation after the re-shaping; thus eliminating the isolation chip to bring added jitter;

3. the independent development of the system clock, using femtosecond CRYSTEK custom clock, ultra-low phase noise, low jitter.

F-1 digital interface of our team to develop a high-performance USB digital audio interface, using the XMOS latest xCORE-200 series chips. F-1 is the rare use of ultra- low-jitter femtosecond clock digital system interface. F-1 digital interface using standard USB2.0 input interface, while F-1 has a wealth of output interfaces, including coaxial RCA and I2S interfaces.

Features:

1. F-1 is the first using the XMOS latest xCORE-200 series of high-end USB digital interface products.New generation XMOS chip, using more advanced processing technology. It’s performance compared to the older U8 chip has doubled, reaching 1000MIPS processing capabilities.

2. it is known, the weight of the core is digital audio algorithms. Our team in the field of digital audio work for many years, at the same time get XMOS FAE support team, we conducted a number of technical improvements and optimization algorithms on the basis of the original firmware.

Screw position, I2S pin position is fully compatible with Italy Amanero module

The entire board with three crystal design, all are imported SMD crystal using active crystal. Wherein the audio

Crystal is CRYSTEK CCHD series customized version of the crystal.
