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 boxes as shown in picture.

Mint condition, includes original packaging and boxes.

Immaculate condition. About just over a year and a half old and hardly used. All original packing, remote control. A very nice DAC usually retails at £3,199. In my opinion a much better all round DAC than the Pavane etc as you get 85% of it for less than half the price. The only DAC I know to show this one up is a DAC by Aqua which retails for £7,500. 4 x DAC3 modules which are the latest and currently unavailable versions of their DAC chip. I could also include the DAC 2 chips, you can then swap them around to see which you prefer and recoup some cash by selling the other set of DAC chips. Takes AES, USB, Optical and Coaxial. Outputs RCA and balanced XLR.

PCM63P-Y BURR BROWN R2R DAC update PCM63P-K (2pcs KOREA) better to TDA1541A-S2 For sale Dac Cip PCM63P-Y of the best audio quality, only used on a fewprofessional equipment, when the best HIFI equipment used the lower K version. These absolutely original chips have been removed from a professionalYamaha processor (see photo), by a specialized technician with desoldering ofthe individual pins to avoid thermal stress on the chip. From the Burr Brown data sheet first version (available on the net) theproduction classes were the following in order of increasing quality. PCM63P PCM63P-1 PCM63P-J PCM63P-K PCM63P-K-2 PCM63P-Y Subsequently the classes were reduced to 3 PCM63P, PCM63P-J, PCM63P-Kwith updated data sheet. When listening, the Y version differs from the K with a fantasticpresentation of the soundstage that widens and increases in depth, with greaterfocus and brightness of the instruments. The sound is very full, round, with alot of body and deeper bass. It is like listening to a class Aorchestra against a class B orchestra: the main one being that each of theinstrumentalists in the class A orchestra not only controls his instrument better,but also produces the best sound quality from his instrument. Same with thisY: everything just sounds richer, theres more resonance, it soundsright and absolutely realistic. The improvement from the K to the Y is similarto or greater than the difference between the normal P and theK. Ive heard recent R2R Dacs with SMD resistors but I think theyare far from this CIP if well implemented with receiver, oversampler andanalogue output stage up to par. The CIP “Y” was produced in Japan and Korea, the Japan productionexhibits a softer and more mellow sound, the Korea production has a neutral andnot “sweetened” sound compared to Japan. The difference between the 2 productions Y and perhaps alsofrom the K is probably due more than to post-production selectionsto different qualities in the materials and raw materials used for theproduction. 4 of each type had been mounted on the yamaha electronics in a randomposition (see photo on the card) probably due to the industrial management withsame code. Packaged in a suitable antistatic box, as shown in the photo For sells outside EU please as quotation PCM63P-Y BURR BROWN upgrade per PCM63P-K (4pcsmade in Korea) meglio di TDA1541A-S2 crown In vendita Dac Cip R2Rdella migliore qualità audio, usati solo su poche apparecchiature professionali,quando le migliori apparecchiature HIFI usavano la versione K inferiore. Questi cip assolutamenteoriginali, sono stati tolti da un processore professionale Yamaha (vedi foto),da tecnico specializzato con dissaldatura dei singoli pin per evitare stresstermici al cip. Dal data sheet Burr Brownprima versione (disponibile in rete) le classi di produzione erano le seguentiin ordine di qualità crescente. PCM63P PCM63P-1 PCM63P-J PCM63P-K PCM63P-K-2 PCM63P-Y Successivamente le classisono state ridotte a 3 PCM63P, PCM63P-J, PCM63P-K con data sheet aggiornato. All’ascolto la versione Yrispetto alla K si differenza con una fantastica presentazione del palcoscenicosonoro che si allarga e aumenta in profondità, con una focalizzazione e luminositàdegli strumenti maggiore. Il suono e molto pieno, rotondo, con moltocorpo e bassi più profondi. È come ascoltare unorchestra di classeA contro unorchestra di classe B: la differenza principale è che ciascunodegli strumentisti dellorchestra di classe A non solo controlla meglio il suostrumento, ma produce anche la migliore qualità del suono dal propriostrumento. Lo stesso con questa Y: tutto suona semplicemente piùricco, cè più risonanza, suona corretto e assolutamente realistico. Il miglioramento dal “K”al “Y” è simile o superiore alla differenza tra il normale “P” e il “K”. Ho sentitoDac R2R recenti a resistenze SMD ma li ritengo lontani da questo CIP se benimplementato con ricevitore, sovra campionatore e stadio analogico di uscitaall’altezza. Il CIP “Y” è statoprodotto in Japan e in Korea, la produzione Japan esibisce un suono più morbidoe dolce, la produzione Korea ha un suono neutro e non “addolcito” confrontatoal Japan. La differenza tra le 2produzioni “Y” e forse anche dai “K” è probabilmente dovuta più che a selezionipost produzione a differenti qualità nei materiali e materie prime usati per laproduzione Sulla elettronica yamaha eranostati montati 4 per tipo in posizione casuale (vedi foto sulla scheda) probabilmentela gestione industriale prevedeva un unico codice indipendentemente dalla produzione.
