T+A DAC 8 DSD D / A converter

Volume control is also unusual for a DAC, but it makes perfect sense if you want to use active speakers or use the DAC 8 DSD together with external power amplifiers as a preamplifier. The volume control is very complex and takes place down to low volumes with analog actuators, so there is no loss of dynamics or channel differences, even at low monitoring levels. It can be bridged with the help of two gold contact relays and is completely removed from the signal path when it is not needed.
It was particularly important to us to develop a very good headphone amplifier with a high power supply capability, which makes the DAC 8 DSD even more universally applicable.

For DSD data that can be supplied from the PC-USB input, we have developed our own, unique converter, the T + A True One Bit DSD Converter. It is completely analog and a real 1-bit converter, because we did not want to use the DSD mode of a PCM converter like other manufacturers. In this way we ensure that DSD data, as in our high-end DSD / PCM player PDP 3000 HV, is processed absolutely unadulterated and without harmful additional conversion in the real one bit stream. 15 years ago we already had the galvanic Separation of the converter / analog section developed, it completely isolates the digital part in the DAC 8 DSD galvanically from the analog part with the help of ultra-fast digital isolators from Silicon Labs. This prevents any interference from entering the analog section from the source devices!
The “state of the art” analog stages are symmetrical and completely discrete and do not use OP-AMPs. Unlike OP-AMPs, they do not get their linearity from a “hard” negative feedback, but from the quality of the circuit design and the components used, which are elaborately selected and adjusted. The DAC 8 DSD also offers a unique switchable analog bandwidth, which has proven itself very well in our high-end players. The analog reconstruction filter of the DAC 8 DSD can be switched between 60 kHz and 120 kHz cutoff frequency. The “Ultra-Wide” setting of 120 kHz allows a perfect frequency and phase response with corresponding broadband power amplifiers, as T + A naturally has.
