難得師兄會試同"fallback to original"!
十分同意音樂感要行先, "靜D"只係錦上添花.

部機成皮半嘢, 咁Q貴, 唔玩盡啲點得! Now, I am working on the Hack to UltraLock2™ Jitter Attenuation System. Hope I can success by this weekend.

Almost done and already performed some testing. Benchmark's USB interface, firmware, UltraLock2™ Jitter Attenuation System are really really good ,low jitter, smooth and stable.

I2S signals were extracted just before ESS9018. Those are the final PCM / DSD signals that have been processed by Benchmar's UltraLock2™ Jitter Attenuation System. It is so difficult / high risk to solder on three consecutive pins of ESS9018.

Once I2S signals have been extracted, they can be sent out to other dac by an I2S to LVDS-HDMI interface. It has been installed into my dac 2. Now, my existing dacs with HDMI-IN(like TDA1541A, WM8741, Wyred DAC2, Buffalo III, ...) can enjoy the super clean and almost jitter-free PCM/DSD signals from Benchmark. After some listening test on various dacs, I would rate a '9' on Ultralock2 and '7.5' on its own dac.

The Benchmark's UltraLock2™ Jitter Attenuation System simply provides upgrade to all my existing dacs. As Wyred4Sound Dac2 and Benchmark are using the same dac with difference mainly on output stage. I don't want to comment on those 2 Dacs based on my subjective view. But, I will say the output stage of Wyred4Sound Dac2 is not weak at all.

只可以又作個比喻, 你話Wyred DAC2 個output stage 靚唔靚?

You can purchase the HDMI-I2S send & receive cards at here.

If you feel comfortable with LAN cable, then you can use 2 pieces of teleporter instead at here

Hi Steve ching,

A question about cubox. Yesterday I got it, and follow your link to download the IMG file, then I use VM Linux format the SD card, and run the
"zcat xxx.img | dd of=/dev/sda". It writes data to the card for about 40 minutes. Then when completed, I disconnect it and put into cubox. However, it just not boot up. I check with "fdisk", it shows two partition (first is 9MB, second is 3.xG, rest of the sdcard), the problem is, it reports cylinder figure for partition boundary is invalid. I tried three times last night but problem still exists. Do you have any idea?

Thx

P.S. I tried using "zcat" command and simply use "7zip" decompress it first and use "dd if=xxx.img" instead but both said partition invalid.

Just found an image writer which gives a more reasonable speed (9MB/sec):

Try tonight when back home to see does problem solved or not.

I have came across boot up problem on some mini sd cards (e.g. all ADATA). I would suggest to use the HKD39 Scandisk 4GB micro sd hc.

I think it should work. One more important / confidential setup within Diskstation, you must create a dummy folder 'Music' under the standard 'music' folder. All your music files must put under 'Music'. Don't ask me why, just do it otherwise cover art won't work.

Thanks Steve Ching,
I am also Synology user, currently, I put my music files in:
/volume1/music/{Genre}/{artist}/{album}/{FLAC or WAV}

So I guess I no need add additional folder.

Then, it must be

/volume1/music/Music/{Genre}/{artist}/{album}/{FLAC or WAV}

I have no idea on Qnap, but let's try it first.
