Denafrips Ares 12th R2R DAC. Purchased in March. This unit is in good working order. Hasnt been used much during the time Ive had it. Includes power cord and all original packaging. It will ship in original outer box as shown in picture.

Vendo questa scheda PCB che realizza da I2S a uscita analogica stereo. Una manciata di porte TTL ed una rete di resistenze R2R ladder per avere luscita analogica. Vengono convertiti fino a 24 bit. A 16 bit gli ultimi 8 sono a zero, non lavorano e sono ininfluenti.Linterfaccia è totalmente in hardware non ci sono CPU. Lavora in modalità non oversampling e accetta frequenze di clock oltre il classico 44.1 Khz. Nelle foto la vedete lavorare a 24 bit 96 Khz I due canali Sx e Dx sono perfettamente sincronizzati. La linearità è garantita dalle resistenze utilizzate con tolleranza di 0.1%. Potete vedere il segnale triangolare in uscita.Prima della rete resistiva sono stati inseriti tre buffer da 8 Bit (totale 24) per aumentare la disponibilità di corrente.In questo modo, rispetto le versioni precedenti, si è potuto abbassare drasticamente il valore delle resistenze R che è stata portata a 600 ohm. Così facendo gli operazionali di uscita non sono più necessari e sono stati eliminati con grande vantaggio sul suono. La bassa impedenza di uscita che si ottiene permette di pilotare direttamente gli stadi di preamplificazione successivi. Gli integrati buffer (HCT244) sono alimentati con una alimentazione a parte di 6V generata da uno stabilizzatore lineare incorporato nel circuito. E possibile selezionare tensioni da 5, 5.5 e 6 V partendo da una 12V di ingresso. Il segnale analogico che si ottinene ha uno swing di 6Vpp pari a 2V rms.Il condensatore di accoppiamento in uscita montato è del tipo al tantalio ma è possibile eliminarlo e montare condensatori personalizzati. Un filtro passa basso passivo anche semplice R-C sarà necessario a piacere eventualmente direttamente montato sui connettori di uscita. Alimentazione 5V DC per il digitale, 12V DC -> 6V per i buffer e la sezione analogica. In foto vedete la PCB completa in funzione. Ottima per costruire il convertitore definitivo senza DAC e senza OP, suono puro diretto dei BIT senza retroazione alcuna di noise shaping o di circuiti di preamplificazione ad operazionali. ATTENZIONE: Si vende esclusivamente la scheda della prima foto. Tutto il resto è mostrato a dimostrazione della funzionalità della scheda ed è escluso. Essendo un dispositivo OEM è destinato a tecnici esperti. Essendo una compravendita fra privato è esclusa qualsiasi garanzia. ---------------------------------------------------- ENGLISH ----------------------------------------------- I am selling this PCB board which makes a stereo analog output from I2S. A handful of TTL gates and a network of R2R ladder resistors for analog output. Up to 24 bits are converted. In 16 bits the last 8 are zero, they dont work and they are influential. The interface is totally in hardware there are no CPUs or DSP. It works in non-oversampling mode and accepts clock frequencies beyond the classic 44.1 Khz. In the photos you can see it working at 24 bit 96 Khz The two left and right channels are perfectly synchronized. Linearity is guaranteed by the resistors used with a tolerance of 0.1%. You can see the triangular signal coming out. Three 8-bit buffers (total 24) have been inserted before the resistive network to increase the bit current output. In this way, compared to the previous versions, it was possible to drastically lower the value of the resistances R which was brought to 600 ohms. In doing so, the output operational amplifiers are no longer necessary and have been eliminated with a great advantage on the sound. The low output impedance obtained allows direct driving of the subsequent preamplifier stages. The buffer ICs (HCT244) are powered by a separate 6V power supply generated by a linear stabilizer incorporated in the circuit. It is possible to select voltages of 5, 5.5 and 6 V starting from a 12V input. The analog signal obtained has a swing of 6Vpp equal to 2V rms. The intalled output coupling capacitor is of the tantalum type but it is possible to eliminate it and mount a customized capacitors. A passive low-pass filter, even simple R-C, will be necessary if desired, possibly mounted directly on the output connectors. Power supply 5V DC for digital, 12V DC -> 6V for buffers and analog section. In the picture you see the complete PCB in operation. Great for building the ultimate converter without DAC and without OP, pure direct sound of BITs without any feedback of noise shaping or op-amp preamp circuits. ATTENTION: Only the card in the first photo is sold. Everything else is shown to demonstrate the functionality of the card and is excluded. Being an OEM device it is intended for experienced technicians. Being a sale between private individuals, any guarantee is excluded.

This listing is for my Musician Audio Pegasus - R2R DAC To my ears this is better than the Denafrips ARES II DAC and only selling due to an upgrade to another R2R DAC and to be honest the sonic difference between the Pegasus and my new more costly DAC is minimal! making this a bargain in the R2R world. It is used but in excellent condition and in full working order with original packaging and instructions. Free postage and will be shipped using Royal Mail special next day delivery with full tracking and insurance for piece of mind. Any questions just ask.

Denafrips Ares II R2R Dac 9/10. I love this DAC! But I see no need in keeping it since upgrading to the Venus II 12th... Yes, it is that good, the reviews are true, so true, I replaced it with a Venus II 12th DAC... I bought the Ares II roughly 1 year ago from Alvin at Vinshine Audio. It does NOT have the latest firmware upgrade, you can do that yourself if you want. Personally, for the money, and owning the Venus II 12th, this Ares II is a steal. It will come in the original shipping box. When I purchased, it did not come with a power cord, but I will throw a good one in for you so you can hook her up right out of the box. The unit is 9 out of 10, no issues, case is scratch free all the way around. I can contact Alvin at Vinshine, and more than likely have the warranty transferred to the buyer, there is roughly 24 months left on it. Happy Bidding! And I will ship out immediately upon close of auction via USPS insured, CONUS only.

Denafrips Ares II R2R Dac. Lightly used before upgrading to Pontus II. Incredible sound and even better since the latest firmware update was installed. Like new condition. DAC and power cable. Not in original box. Will be carefully double boxed for shipping.

Denafrips Pontus II 2 DAC Digital Audio Converter. This DAC made my previous DAC sound like it was broken , such was the difference. It really is an astonishing bit of kit. I purchased this in March 22 from Vinshine Audio as part of my bid to build my dream HiFi so still has nearly 2 years warranty left. Denafrips are an amazing company that continue to support their DACs - they have just released an FPGA firmware update for this DAC - I havent installed it so the buyer can have the choice of whether to do it https://www.denafrips.com/firmware-update There is a small scratch on the top right of the faceplate that was sustained in the shipping from Singapore to the UK, I have and will include with the sale a new faceplate Denafrips sent as compensation but I never saw the need to fit it. I also have for sale a Denafrips Iris DDC which essentially upgrades this to a Venus DAC with its improved clock. It also allows USB to be converted to I2S If youre looking at this advert, the chances are you know what an amazing DAC this is, I have a genuine reason for sale that unfortunately we rescued a dog who really doesnt appreciate my HiFi - and as you will see the rest of my high end set up is also listed on here - please check my other items. I would prefer collection where it can be demonstrated workingHappy to post , I have all original packagingAny Questions please feel free to ask.
