Product Description
The Luxman DA-07X DAC is a top-of-the-line DAC. High-end DAC chips by ROHM are used in dual mono mode. Support is also provided for high data rate PCM, DSD, and MQA. The fully balanced design provides a clean and smooth output with exceptional clarity.
Next, there is a wide range of inputs including two optical and two coaxial inputs as well as USB. The front panel display shows which input is in use as well as the audio format. The display can also be turned off. Lastly, balanced outputs are provided as well as standard RCA outputs.
High-performance DAC chip from ROHM
The DAC chip fitted to the Luxman DA-07X DAC is made by ROHM and used in dual mono mode. ROHM Semiconductor is renowned for its high-end DAC solutions. Additionally, the unit supports most of the available audio formats, including, 768kHz 32-bit PCM as well as DSD up to 22.5 Mhz. There is also comprehensive MQA support.
A fully balanced design
The analogue circuitry in the Luxman DA-07X DAC is fully balanced. For example, the differential output from the dual mono configuration drives a discrete buffer stage. There is then a low-pass filter circuit that removes any digital noise. Lastly, a digital filter switch is available and anti-jitter technology is used to deliver a clean and stable output. DIN-balanced outputs are provided.
Good connectivity
As well as USB there are two RCA coaxial inputs as well as two optical Inputs. Many devices can be connected without any lead swapping. There is also a professional EBU input. Outputs include standard RCA connectors as well as two balanced outputs, one for each channel.
There is also an additional coaxial and optical digital output. Lastly, trigger inputs and outputs are provided for remote on/off switching.
What is A DAC?
Modern music sources are mostly digital and there are many formats. PCM is mostly used by CDs while DSD is used by some movies on disk and online. DACs convert the digital stream back into music using a chipset. The quality of the chipset is important, and the chips used in the Luxman DA-07X DAC are made by ROHM, one of the top manufacturers.
Some digital sources can suffer from jitter. Jitter is a displacement in the digital signal, In the case of CDs it is caused by rotational instability. As a result, the Luxman DA-07X DAC and other high-end DACs have jitter removal circuits to provide a stable output.
Lastly, MQA stands for Master Quality Authenticated and is a high-end format aimed at audiophiles. Only high-end DACs such as the Luxman DA-07X DAC support this format.
Why a separate DAC?
Built-in DACs are sometimes added as an afterthought, Consequently, the main advantage of the Luxman DA-07X DAC is its performance. Lesser DACs are not balanced nor do they have such comprehensive input capability. In fact, most DACs only have two or three inputs.
Another high-end feature is MQA support, this has to be licensed so is less often a feature of DACs. There is also the separation of low and high-level; signals. DACs integrated into amplifiers have to be shielded from the magnetic fields of the surrounding large transformers.
