When I'm not using the tubed Stibbert V CDP as a transport I replace it with this solid-state Audio-gd CD7SE transport. I'm having a very difficult time deciding which one I prefer. Hope I can soon, so I can sell the other. At the very same time it's nice having a choice between the two!

1) Configuration: Multiple, independent shielding of Power transformers, power supply, signal processing, disc drive , coaxial output circuit, and clock circuit to avoid interference with each other. To further enable the machine to achieve the best results, Audio-gd uses a heavy-weight pure aluminum alloy chassis to stop interference of eddy current of the transformer on the line and all kinds of vibration, the net weight is 13KG.

2) Jitter: The use of low-jitter clock and power driver circuit, independent and parallel dual regulated power supply circuit of the clock power supply, ensures clean and stable clock signal.

3) The CD-7 Final Version employs a high performance SONY DVD disc player, it can accurately and quickly read the data, and reduce error data, with computing power and strong signal of the DSP processor, it has 64MB memory. Audio-gd has redesigned the system by removing the DVD functionality, as a result it only plays CD disc, the DSP computing power is equivalent to Pentium 2 computer, hence it can better perform signal and processing operations, resulting ultimately in sound quality improvement. General load CD dedicated processing circuits, such as Philips and the CDM4, have a memory of only 4KB, which is only equivalent to a 286 grade/level of computer.

4) Coaxial out: No matter how good the data processing circuit, the SQ also depends on the coaxial output transmission circuit, CD-7SE Final Version uses current digital signal transmission ---{like CAST in Krell}--- which can better minimize the impact of JITTER on the digital signal sent to DAC, this circuit is compatible with 99% of standard market designed DACs , the sound quality is much better than the traditional IC or transistor output circuit, it is more comprehensive and significantly reduces the demands on the coaxial cable. CD-7SE Final Version also has another built-in high-performance coaxial output, which is a transistor circuit and has been well received by users for many years, most users agree that the sound quality is better than traditional IC output circuit. This circuit is also the first of its kind in the world and designed by Kingwa and the original version of the circuit was posted in the in 2005. The user can output through the use of different circuits or different output sockets and the sound quality will be different from each socket.

5) Power supply: CD-7 Final Version uses three R-core transformers to match different electric circuitry. The power transformers and rectifiers are carefully shielded from the electric field of the power transformers and rectifiers' frequency transmission. More than 38,000uf audio grade NOVER capacitors are used to ensure ample and smooth power feed. The NOVER capacitors are specially custom order by NOVER (U.K.) according to Audio GD's requirement. A total of 10 PSU groups are applied. 8 groups of Class-A parallel voltage regulators are combined into two groups of cascade-like parallel voltage regulators to lower the internal resistance and to purify power supply. To achieve Silent operation, the control circuit and motor serve circuit are powered with separate regulator.

6) Output sockets: CD-7 Final Version has two RCA coaxial and two BNC coaxial outputs, they are all 75 ohms. BNC has the least JITTER, 10 times or even lesser than balanced digital output. RCA sockets will suit the tastes of a little softer listening preferences of different users.

7) Function: CD-7 Final Version has automatic playback, it comes with a multi-functional remote control (such as direct selection of tracks and many other functions) made out of pure aluminum alloy. It h
