Zhaolu announced D3!

That Ethernet Connection is very interesting. Ethernet is the only way to get low jitter levels out of a PC. Ethernet basically transforms your PC into the realm of a very expensive transport.

I agree that a PC (or any hard-drive-based media computer) is better than a mechanical one. The PC has no "real-time" information other than the assumed sample rate, so it essentially has to re-clock the data to make it look like redbook (or any other standard). The quality then does not depend on transport error rate but on the quality of the output clock and system noise only. Both of these "problems" are theoretically easier to resolve compared to a spinning mechanism...
It's funny that at the time we considered the CD media revolutionary and the turntable clunky... Now the CD looks just as archaic, I'd say...

The VIA Vinyl Envy24MT Audio Controller is optimized for applications such as notebook audio with a low profile design, and ultra-low power requirements. Featuring support for a number of PC interfaces the VIA Envy24MT Audio Controller can be integrated onto PC motherboards, Mini-PCI cards, or PCMCIA cards. This design flexibility allows the VIA Envy24MT to be used as a standard Peature, an add-on within a system, or integrated into external audio devices. ~1{2T!F.g{I f

The VIA Envy24MT Audio Controller supports the latest 24-bit/192kHz high fidelity content through analog stereo inputs and outputs, as well digital audio connections. For audio workstation applications the Envy24MT also supports two MIDI ports, and low latency drivers such as ASIO.e^"Z#} v

What results is an audio solution with tremendous dynamic range making music more alive from the thundering booms of the bass to excellent mid and high frequency response. Combined with professional audio DACs, the Envy24MT becomes a serious hi-fi contender for playback and recording.

Input/Output
2 synchronous I2S / AC-link output data stream pairs
2 synchronous I2S / AC-link input data stream pairs
Multi-channel AC-link support
Integrated S/PDIF transmitter with IEC958 line driver
Digital loopback and stream routing mechanism
Peak meters on all streams
MPU-401 MIDI UART port
ACPI and PCI PMI support




Here is a translation of the Zhaolu D3 announcement:
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 :
-115dB -115dB (A-weighted)
113dB dynamic range (A-weighted)
<-100dB £¨<0.001% Total Harmonic Distortion : "-100dB (" 0.001%)
-111dB 1KhZ -111dB 1KhZ stereo separation :
-108dB 300hZ -108dB (300hZ--40KhZ)
Zhao-lu D3 use Cirrus logic IC produce nuclear CS4398 digital-analog conversion heart devices, carefully match the peripheral circuits, Zhao-lu well reflected in the structure of the circuit design capability, Moreover, Zhao-lu consistent refinement of the production model, Zhao-lu D3 digital audio decoder to ensure that most users the highest Blair to meet the demands!

I found more information about the TG-Link at a forum on pchifi.cn.

But I not too believed once infatuatedded to the research chip polishes technical the company to be able also to have the similar attainments in this aspect. The I2S patent is the Phillips company. I2C is the Phillips company's patent. I was saying the tongue twister? Does not have. Catches up with bright me also to apply for a patent for these two speeches combination way to go. ...

Popofox and leve also refer it to two Chinese patents. See Thread #47 http://www.pchifi.cn/viewthread.php?...extra=&page=3#

Two PDF files are mirrored at TG-Link.rar. The patent is 200510024999.4 G10L19/00 (2006.1).

Be prepared for Chinese articles. Don't blink your eyes.

Woah, that's a major breakthrough man!

Anyway, anyone have any idea when is the release date for D3?

The SPDIF has a "noise filter" in the receiver. It's called a PLL. The I2S does not. So which is really better?!

But the cable is usually shielded so it won't pick up the noise. I2S seems much better than SPDIF

nuclear heart devices...

[deuginthesky]

I am confused, I can't see any snubber on the pics, how will be made the current conversion ?

[yrh0413]

its hidden under the metal shields, either near the front or the side.

[deuginthesky]

Do we know when it will be for sale ?

I'm planing to buy soon another D2.5a and also a D2.5c to compare.
