About the DAC 07
The new DAC 07 is a complete new design. Again most of the efforts has been put into the power supply. The use of capacitors and chokes has lowered the noise even more. Also the DAC chip has been upgraded to a 32 bit converter.
The input range has been extended to 3 optical 3 RCA 1 XLR and 1USB. (Different customer options are available)
The output now has both single ended RCA and Balanced XLR. Both outputs can be used at the same time.
A few testimonies are available at the facebook page Newontech
This converter is based on the 32 bit Burr Brown DAC chip PCM1795. This is a DAC chip designed for high end applications. The Receiver is a Crystal CS8416. The power supply is based on high quality regulators LT317 / LT337 for the analogue section, and LP2951 for the digital section.
The construction is fed from two different windings from a well over-dimensioned transformer. And six different supplies are included on the PCB giving a clean and stable supply for each circuit.
The output stage is made of the LME6172 op-amp, which is a very high slew rate / bandwidth amplifier. The PCB is specially made for audio, and has been manufactured using a specially plating process. This process is usually reserved for Space applications. The process gives a very fine and compact cobber structure.
Every board is hand soldered to insure a strong and lasting connection. And different types of solder are used for the analogue and digital parts. For the analogue section a special clean tin is used, this is an ESA / Space approved tin. This is new tin and not reused tin as in most ordinary solder wire.
