Mitski sounds lush and organic in her Be The Cowboy album, as long as we avoid the grunged-up effects on tracks like Why Didn’t You Stop Me? and Blue Light. Two Slow Dancers brought her into my living room and its correct tonality made things all more believable. It was the same with Run Your Finger Through My Hair by Blues Company. This invitation to the blues cannot be declined as I found myself listening to the Ares into wee hours.THE LAST WORDThe Ares is a worthy competitor to other DACs regardless of their architecture, and has been a staple for people who want to venture into R2R territory.If you’re looking to upgrade from your entry-level DAC, you should definitely give the Ares a try. Its effortless presentation and expansive soundstage, especially at this price point, makes choosing it a no-brainer.

HIFIMAN EF400 Desktop Headphone DAC & Amplifier R2R DAC In great condition and works great. Please look at all the pictures. It comes with everything in the pictures.

Gustard R26 R2R DAC in black finish. Includes remote. I don’t have the manual but I’m sure you can find it online. Has a few light scuffs from moving into and out of rack. But otherwise functions perfectly. I have the original box and quite heavy for a DAC. Free shipping in contiguous USA only. Thanks for looking.

Used but in great condition EF400 R2R DAC/Amp. Comes with original box, USB cables, and power cable.

This is a Denafrips Pontus II, a very special R2R DAC which has served me well for a couple years now. It has never skipped a beat regardless of input used. Selling because I am taking my system in a different direction. No original box. Enjoy! Capabilities listed below: ADAPTIVE FIFO BUFFER RECLOCKINGThe DENAFRIPS approach to address the jitters issue by FIFO BUFFER RECLOCKING. The adaptive FIFO buffer store the source digital audio data in the memory. These data are read from the memory using the low phase noise, precision FEMTO Clock, located right in the DAC.This technology is close to the perfection, especially so with the local FEMTO Clock. The jitter is so small that it can be neglected.PROPRIETARY, STATE-OF-THE-ART USB INTERFACEThe PONTUS is equipped with the proprietary USB Audio Solution, powered by STM32F446 Advanced AMR Based MCU. DENAFRIPS redesigned and optimized circuitry, allow the DAC to be used as high-end DAC with computers / streamers. It supports 24bit/1536kHz PCM data stream, and native decoding of DSD up to DSD1024. It comes with licensed THESYCON USB Driver for Windows Platform.PROPRIETARY SPDIF DIGITAL AUDIO RECEIVERThe SPDIF Coaxial, Optical, AES/EBU input support up to 24bit/192kHz digital audio format. The PONTUS abandon the use of Digital Audio Receiver chip. The digital data is decoded by the on-board FPGA (Field Programmable Gate Array), signal path is shortened and eliminated the undesirable coloration.PROPRIETARY R-2R AND DSD DECODING ARCHITECTUREThe PONTUS is equipped with 24Bit R-2R DAC to decode PCM data stream and 32 steps FIR analogue filters hardware decoder to decode DSD data stream. These designs guaranteed the PCM format can be perfectly decoded, at the same time, the DSD format can be perfectly decoded as well. It is rare in the currently market that a R-2R DAC can hardware decode both the PCM and DSD formats.There is also a picture of the internal architecture with the following description:DIGITAL SIGNAL PROCESSING – All digital input data are stored in the on-board FPGA high-speed RAM.FEMTO CLOCK – These data are read from the memory using the low phase noise, accurate FEMTO Clock, located right in the DAC. The processed data are sent to the final stage Discrete R-2R, for DA conversion.R-2R LADDER NETWORK – The data bits are converted to analogue signal by the true balanced R-2R ladder network arrays. The linearity of the conversion is guaranteed by the high-precision thin film resistors, with low thermal effect temperature coefficient of the low 10/15ppm.

This is a very solidly made, mellow sounding DAC based on the AD1865 chip. NON oversampling or NOS design. Excellent Condition. Works as it should. Cosmetically excellent (with some very fine scratches) Finished R2R Decoder AD1865R NOS double parallel DAC decoder
