The Virtuoso — Roon Ready Network DAC
I will never go off key.
Many DACs let you shape your music by tweaking digital filters.
After all, there’s only one way your music is supposed to sound–the way it was recorded.
Roon is the most engaging, enjoyable way to browse your music.
Together, Roon and Musica Pristina deliver the power, flexibility, and performance benefits of networked audio, with the easiest setup and highest reliability available.

Why Choose A Virtuoso Network DAC?
- 4 inputs
- S/PDIF (Coax RCA), AES-3id (BNC) and AES/EBU (XLR)
- Ethernet (Cat 6, requires Roon)
- Dual mono D/A circuitry
- Up to 24 bit / 192 kHz resolution
- Dual mono analog circuitry
- Fully balanced signal path
- Differential vacuum tube (6H30P) gain stage with integral power supply
- Analog discrete resistor stepped shunt attenuator
- Frequency response / bandwidth: 10Hz to 100KHz (-0.3dB)
- Total Harmonic Distortion 0.07% (THD)
- Balanced (XLR) Stereo output
- Single-ended (RCA) Stereo output
The Virtuoso sports four inputs. The first input is an S/PDIF on a Coax RCA connector. The second is an AES-3id input on a BNC connector. The third input is AES/EBU on an XLR connector. The fourth input is an Ethernet port providing access to a built-in Roon Ready player.
Why no USB input — the “U” stands for Universal after all? First, we believe that Ethernet based audio is the best path forward for storing, controlling and transmitting digital audio data signals. Second, we think USB is a second class citizen when it comes to audio playback, evidenced by the plethora of workarounds available on the market today (dedicated PCIe USB cards, supplemental USB power supplies and USB reclockers to name a few).
All inputs are galvanically isolated from the DAC Board. This ensures that external devices, and their inherent noise, does not pollute the the internal circuitry, nor other input devices.
Fed by isolated inputs, Digital to Analog conversion is performed by a pair of Burr-Brown 1794 DAC chips. Each IC is used in mono mode to create one channel of the Virtuoso DAC. Each channel provides the signal as a differential current output.
On the DAC board, power for the digital section is separate from that of the analog section. The analog section of the DAC board is fed by ten (10) individual regulators, each with its own purpose.
The current output from the DAC chips is passively converted to voltage by an array of tantalum resistors. This voltage represents the low-level analog audio signal.
The dual mono analog amplification section is fed low-level analog signals from the I/V circuitry. A differential vacuum tube (6H30P) gain stage, with an integral power supply, is used to provide fully balanced outputs at 2VRMS Max.
Each channel is powered by its own current regulated power supply.
This amplifier uses a stepped shunt volume control implemented with high quality discrete resistors.
The Virtuoso provides 2VRMS Max Output on either XLR or RCA connectors. A switch configures balanced or single-ended output on both output connectors.
