Pro-Ject DAC Box RS Final Edition – DAC on ECC88 tubes
Pro-Ject has released the Pro-Ject DAC Box RS Final Edition digital-to-analog converter – the new product features a pair of audiophile Diamond ECC88 tubes. All circuit elements of the Pro-Ject Audio DAC Box RS Final Edition have undergone a special selection, and the internal wiring has also been upgraded. The DAC output stage is implemented in a balanced circuit, while the tube circuit can be either connected or disconnected using a button on the front panel.
The Pro-Ject Audio DAC Box RS Final Edition DAC offers a rich commutation set, which includes an I2S input with Master Clock, a balanced AES/EBU input, an optical Toslink, a coaxial input, and a USB-B port. The DAC is capable of decoding audio in DSD formats up to DSD128 and PCM up to 24 bit/192 kHz. The new product is based on a pair of Texas Instruments PCM 1792 chips and offers a choice of digital filters.
If desired, the included DAC power supply can be replaced with an optional Pro-Ject Power Box RS2 linear source based on a large toroidal transformer. The Pro-Ject Audio DAC Box RS Final Edition is already available in Europe at a recommended retail price of €1,199. The optional Pro-Ject PowerBox RS2 power supply is available at a price of €999.
