hugoboss said: like you said the new xmos moving so fast . diynhk already released their own xmos xcore 200 chipset 16 cores but it's diy board XMOS 768kHz DXD DSD512(DSD1024) high-quality USB to I2S/DSD PCB World's first Real 768k USB to I2S/DSD PCB for audiophile Diyer to enjoy! dsd 1024 waow The Xmos used in this pcb is XU216 2000MIPS and it contains two tile. It is equal to two XU208 combined in one chip, one dedicated tile is used for the USB data and the other tile is dedicated to process the audio data with the DAC. This PCB uses linear regulator and it do not have onchip/onboard DC-DC switching converter. It is power hungry(due to linear regulator) but it should favour many people who do not like to use DC-DC convertor. The xmos in this PCB is clocked directly from 45.158Mhz and 49.152Mhz audio oscillator, the timing and jitter is at less two times better than PCB uses 22.5792MHz 24.576Mhz audio oscillator. it claim double the f1 1000mips to 2000mips and using ndk crystal clock it cost us89.5 1) Newest XMOS XCORE-200 2000MIPS 2 Tiles 16 Cores upto 2000MIPS in dual issue mode 2) 4 layer PCB, Solid ground plane (a must for high speed digital circuit) 3) NDK NZ2520SD Ultra low phase noise oscillator and Murata capacitor sourced from Japan directly (guarantee no fake product from China) According to the official datasheet, the phase noise of NZ2520SD is much better than the famous crystek 957 under 25khz(human listenable range) For easier comparsion(lower is better), we overlay the two phase noise graph at the same scale, under 25khz(human listenable range) nz2520sd(red line) is better, over 25khz(human unlistenable range) crystek 957 is better. 4) Dedicated I2C port for the OLED VU meter display to avoid using the same I2C port control the DAC/ADC chip(if needed) which can causes interference to the DAC/ADC chip (common fault in most design on the market) 5) OLED display is the latest technology with highest contrast, complete dark background, full viewing angle and it looks much better than the commonly used LCD display. 6) Full copper one piece housing, gold plated(not cheaper gold flash) high quality Molex USB connector. 7) Compact size 50mm x 50mm 8) PCB is powered by external 3.3V(800mA max. 400mA typ.) regulated supply, it is usually connected to the same 3.3v digital power DAC is using(warning: over-voltage or reverse-voltage can damage the xmos chip immediately, double check before power on) damn to fast now. can you imagine 16core only for usb also it claims ndk is more better than crystek i hope u got your damaged dxiopro board replaced with this thing! if you see cleary seems like diynhk want to beat the singxer face to face . with its spec claim. (double the xmos xcore 208) now we just wait if diynhk will released a finished product like dxiopro 4a to compete with f1, or maybe even su-1 gonna be interesting! now melodius, breeze, gustard where is your xmos 200 product . it's hot now! we can said now 2016 is the year of USB AUDIOPHILE EVOLUTION Click to expand...

This is different then the Pro4a, it uses 16 core, 8 for USB conversion, 8 cores for the DAC conversion. The new XMOS 200 series has the ability to do Digital Audio Conversion. So it's basically a one solution digital source on a single board. They continue to misread the NDK chart on the comparison between the SD and the Crystek CCHD-957. The 957 has better phase noise over 2500Hz, not 25KHz. They're mireading the log freq scale.

hugoboss said: yeah xmos 32 cores it think some people will buy it even it cost double the 16 core after 32 core etc etc etc is there any excuse like "poor usb computer" i think usb will beat i2s connection in the future so lets just hope someday it happen. if usb can beat i2s (hdmi or rj45) we dont have to buy any converter , any *** converter whatever lets hope! Click to expand...

USB is a different conversiin then the one i2s handles. So the need for either a separate DDC or an internal one, usually on a separate board. The DDC can output the processed digital stream as either SPDIF or i2s. Usually both. I2S was developed as an internal connect, inside a CD player, between the transport (cd spinner), and DAC board. It was made for very short cables, inches, not feet.

Now the question is - how good of a sounding DAC these new XMOS 200 chips will be. I'm more interested in the XMOS for USB conversion, then DAC conversion. But who knows.

  Hmm, it doesn't have a dac inside.   One die (tile) with 8 cores is used for USB signal handling   AND   One die (tile) with 8 cores is used to handle digital audio processing, which means: conversion to SPDIF and I2S   XU216 has 2 die's (tiles) . or wafers, in one chip, and in total 16 cores - 8 per die (tile, wafer) Hifiman HE-400i with Defean Lambskin leather pads + Balanced cable / KZ-ZS10 + Balanced cable / Zishan DSD AK4497EQ modified version / Topping NX4 DSD (for sale) / Sennheiser HD250 Linear (for sale)

Well it's confusing as they mention:  From the DIYinHK ad you posted:

Joined Apr 12, 2013 Posts 5,930 Likes 515 So the XMOS Xcore 200 have the ability to output analog (that is what a DAC does convert digital to analog), but also output I2S, SPDIF, DSD/DoP.   It also looks like it can accept a SPDIF digital input.   So the question is what is on that flat cable pin output.  I bet analog outputs, SPDIF inputs.  But better performance to 768kHz (kinda ridiculus at this level which 2 times DxD) to a AKM 4495.     Anyway - maybe this could also be the precursor in the new XMOS speed, cores wars! And what the Pro4a will be based on. One issue is going to be the extra power draw from 16 cores vs 8 cores.  

PCB is powered by external 3.3V(800mA max. 400mA typ.) regulated supply, it is usually connected to the same 3.3v digital power DAC is using(warning: over-voltage or reverse-voltage can damage the xmos chip immediately, double check before power on)  Click to expand...

Yes it does - but seems to work fine with the Breeze 3.29 driver as well.  Looks like it needs no 'driver handshake' like Gustard U12.  In fact both S-1 and X-1 work. Open install!  Nice!  These signed drivers are a pain.   Just paid for my shipping - EMS the second F-1, X-1 and Q1-S in one package.  I noticed some changes in the second X-1 - notably a Murata transformer for SPDIF.

More the merry!  Better clocks this time?  I sure hope so.  I think Singxer and DIYinHK have raised the bar to NDK SD or Crystek CCHD.  Enough of those $5 JYEC OEM TXCO's!!!
