Default New Zhaolu D3 DAC with TG-Link for PC Hi-Fi

Zhaolu annouced the new version, D3. It comes with TG-Link input which looks alike the RJ-45 port. This link seems to be only available on Chinese PC Hi-Fi products.

TG-Link is the best thing since sliced bread

That's what they said about CD's too, I remember.


What is TG-Link?
give me the detail's not the hype,

A quick translate.
The test results are a bit messy to read.

Zhao-lu D3 decoders Preview



Zhao-lu electronic format forthcoming while supporting SPDIF and TG-link D3 decoders, Please pay attention.

Zhao-lu D3 stereo digital audio decoder is a new generation of high-standard decoder products. Zhao-lu company is well-prepared for medium and market products, while ensuring the objective test target, fully allow users to listen to the most correct, the most pleasant voice.
Zhao-lu and TG-link D3 can accept SPDIF digital audio signal format. These two signal transmission to ensure that users can listen to hi-fi music program, four digital input interface can completely meet user requirements, which are : SPDIF optical interface. two coaxial SPDIF input interface with the high-speed buffer TG-link personal computer and a digital audio interface. Through the control panel, users can choose to facilitate the necessary port to accept digital audio signal, and, Users can use the designated priority switched digital audio input, when switched on again. Zhao-lu D3 decoders will automatically choose this as input port to facilitate users to determine their most commonly used listening equipment.
For the pursuit of excellence in performance, Zhao-lu D3 will be prone to interference shielding components, circuit and PCB design and a substantial increase in investment in selected parts, etc., with encouraging results : Zhao-lu D3 test results exceeded the minimum resolution of the test equipment.
Following is a 24bit/96kHz some of the test results :

any details on how to plug the zhalou d3 into a PC?

I'd think the TG link connection would reduce jitter that can come in an spdif connection, so it sounds good.

but how is the tg link achieved. is there a special cable required - or connected via ethernet port. if not special cable, is there a usb->tg link interface card and windows vista drivers?

Default TG-Link : Chinese Patent

I did a detective job and found more information about TG-Link at www.pchifi.cn recently. People there mentioned about two Chinese patents.

Patent 200510024999.4

This was practical new has promulgated one kind of audio frequency data treating plant, this equipment included: The digital audio frequency data handling component ydo, installs in the PC main engine end, processing numeral audio frequency data; The first transmission installment, installs in the PC main engine end, may correspond connected with the digital audio frequency data handling component ydo; Arranges/the decoding and the simulation processing module, is located outside the PC main engine end, arranges/the decoding numeral audio frequency data and carries on the digital-analog conversion, but also carries on processing to the analog-digital audio frequency data; The second transmission installment, installs in arranges/the decoding and in the simulation processing module, carries on the correspondence with the first transmission connection and may correspond with arranges/the decoding and the simulation processing module is connected. Has used this practical new technical plan, embraces the audio frequency the numeral and the simulation partial independently comes, the PC end only makes the numeral tonic train signalling operation processing, but will arrange the decoding (digital-analog/a/d conversion) and its the simulation audio frequency processing electric circuit partially moves to the exterior independent installment processes, in this kind of processing method thorough settlement existing technology question.

FYI, for translation, just copy Chinese text put into BabeFish's text area and select Chinese-Simp.

PS For those who need to check Chinese patents. All in Chinese though. http://www.cpsfu.com/G10L/2006/list4.shtml

People laughed about Japanese inventions and Japanese products 30 years ago. Now, they are desperately looking for obsolete Japanese transistors (Toshiba JFETs, Saken BJTs....), some even from that time (e.g. Sony Power JFETs).

I am very much looking forward to what people have to say about Chinese products and Chinese designs in 10 years' time. With a population of 1.6 billion, they have their fair portion of extremely intelligent people.

If you don't take my word, just ask anyone working in the semiconductor industry, or even the magnet industry. They conquered the world market for magnets in 5 years, and now control 80% of the world's magnet supply. Even if you buy a motor from Maxon for your DIY LP, it has Chinese magnets in them. Not to speak of your Philips or Sony CD laser head.....

And if you would forgive me, I deal with patents daily in my work. I don't recall seeing Australian patents other than an example of one hanging on the wall of our patents office -- a recent patent for a latex nipple for babies.
