dCS Bartok Review: Part 1
▾
Pros
• All in One Box (With Headphone Amp)
• Ring DAC Quality
dCS Bartók uses the very latest dCS Digital Processing Platform and Ring DAC™ technology, originally developed for the Rossini series.
• DXD Upsampling
Featuring DXD upsampling as standard, the multi-stage oversampling design offers optional DSD upsampling plus an extensive selection of DSP filters to suit individual taste and music choice.
• Upgradeable Firmware
Its single FPGA offers streamlined signal processing and superior flexibility, effectively making it future-proof.
• Balanced XLR4 Headphone Output
• MQA Decoding and Rendering
• Broad Connectivity
Bartók plays music through an array of industry-standard USB, AES or S/PDIF digital inputs. It can stream over Ethernet from a NAS drive or online music services such as TIDAL™ or Spotify™, and from Apple devices via Airplay™. The network interface can perform full MQA™ decoding and rendering.

Digital Inputs
Network interface on an RJ45 connector – acts as a UPnP™ renderer in Asynchronous mode, streaming digital music from a NAS or local computer over a standard Ethernet network, decoding all major lossless formats including FLAC, WAV & AIFF at up to 24 bit 384kS/s native sample rate, plus DSD/64 & DSD/128 in DFF/DSF format. Other formats include WMA, ALAC, MP3, AAC & OGG. Some formats are limited to lower sample rates. Supports Apple AirPlay at 44.1 or 48kS/s. Network Loop Out connector on a second RJ45 connector. USB 2.0 interface on a B-type connector operating in Asynchronous mode, will accept up to 24 bit PCM at up to 384kS/s plus DSD/64 & DSD/128 in DoP format. Operates in Class 1 or 2 mode. USB-on-the-go interface on type A connector operating in Asynchronous mode, streams digital music from a flash drive at up to 24 bit 384kS/s plus DSD/64. 2x AES/EBU on 3-pin female XLR connectors. Each will accept PCM at up to 24 bit 192kS/s or DSD/128 in DoP format. Used as a Dual AES pair, it will accept PCM at up to 384kS/s, DSD/64 & DSD/128 in DoP format or dCS-encrypted DSD. 2x SPDIF on 1x RCA Phono and 1x BNC connectors. Each will accept PCM at up to 24 bit 192kS/s or DSD/64 in DoP format. 1x SPDIF optical on a Toslink connector will accept PCM at up to 24 bit 96kS/s
•
Analog Outputs
Output levels: 0.2, 0.6, 2 or 6V rms for full-scale input, set in the menu. Balanced outputs: 1 stereo pair on 2x 3-pin XLR male connectors. These outputs are electronically balanced and floating. Output impedance is 3Ω, maximum load is 600Ω (10k-100kΩ is recommended). Unbalanced outputs: 1 stereo pair on 2x RCA phono connectors. Output impedance is 52Ω, maximum load is 600Ω (10k-100kΩ is recommended).
•
Headphone Outputs
1 stereo balanced pair on 1x 4-way male XLR connector. 1 stereo unbalanced pair on 1x 6.35mm (1/4”) 3-pole jack. Full-scale output levels are 1.4W rms into 33Ω, 0.15W rms into 300Ω. Output levels are 0, -10, -20, -30dB, set in the menu. Minimum headphone impedance is 33Ω.
•
Wordclock
2x Word Clock Inputs on 2x BNC connectors, accept standard word clock at 44.1, 48, 88.2, 96, 176.4 or 192kHz. The data rate can be the same as the clock rate or an exact multiple of the clock rate. Sensitive to TTL levels. Word Clock Output on 1x BNC connector. In Master mode, a TTL-compatible word clock appears on this output.
•
MQA
Full decoding and rendering of MQA data from the Network and USB2 inputs. Final rendering of unfolded MQA data only from the other inputs.
•
Residual Noise
24-bit data: Better than –113dB0, 20Hz - 20kHz unweighted. (6V output setting)
•
L/R Crosstalk
Better than -115dB0, 20Hz – 20kHz
•
Spurious Responses
Better than -105dB0, 20Hz – 20kHz
•
Filters
PCM mode: up to 6 filters give different trade-offs between the Nyquist image rejection and the phase response. DSD mode: 4 filters progressively reduce out-of-audio band noise level.
•
Conversions
DXD as standard or optional DSD upsampling
