Hifiman EF400 DAC/amp. It is used but like new, no show of any wear or damage. Great DAC/AMP, I used with my hifiman HE1000. Time to change it up and switch to something different. Black Dragon cable is included with purchase, over a $200 cable that improves the audio of the amplifier.

Immaculate condition. This is essentially the Metrum Onyx DAC with the addition of a quality pre amplifier. All original packing, remote control. Just over a year old. Nearly a year warranty period remaining. A very good DAC usually retails at £3,199. 4 x DAC3 modules which are the latest and currently unavailable versions of their DAC modules. I will also include the 4 x DAC2 modules, you can then swap them around to see which you prefer and recoup some cash by selling the other set. Takes AES, USB, Optical and Coaxial. Outputs RCA and balanced XLR. Id put the pre amplifier section up with Hugo TT. Signature sound is not far off the TT also as a DAC in general but a bit leaner and thus probably a little more revealing. ****Buy with confidence. On ebay 20+ years, sold many good pieces of hifi. Not a negative feedback ever****

Holo Audio May Level 2 R2R DAC in good/very good condition, fully functional with no issues. Few small scratches here and there (as seen on pictures), originally purchased from Wildism Audio. Comes with original boxes and all accessories. Im the first owner, selling as Im unfortunately downsizing my system. Key features and technologiesHoloAudio Mays next-generation linear compensation technology resolves accuracy errors caused by resistor tolerance after compensation, achieving a 0.05% variance in tolerance accuracy. The integrated proprietary anti-jitter system drastically reduces the level of jitter without increasing the background noise or negatively impacting the sound reproduction.Based on this innovative design, the May is capable of delivering a SINAD of over 115dB and a dynamic range of over 130dB, corresponding to the highest performance that an R2R DAC can achieve today.The May also takes advantage of the exceptional performance of PLL+FIFO technology for an ever lower jitter level. It uses a high-performance femtosecond VCXO as the PLL clock source.On the power supply side, the two mono channels of the DAC are independently powered by their own dedicated transformer. An optimized construction allowing a better separation of the channels while limiting the interferences, in order to reveal a wide sound scene.An architecture that also allows HoloAudios DAC to natively support, via its USB and I2S inputs, high resolution streams up to PCM 32bit 1536kHz and DSD1024. The two XMOS XU208 USB interfaces use proprietary firmware developed to ensure very low latency and reliable data transmission. The May also features two independent I2S inputs over HDMI, each with an independent 4-channel circuit, making the clock signals less susceptible to interference and jitter than in a conventional LVDS system. Each I2S input can be configured with a different pinout for maximum compatibility. NOS & OS ModesThe HoloAudio May offers several convenient configuration options. For example, a NOS mode can be activated to cancel any oversampling, with the original data going directly to the converter. This mode may allow for some distortion problems.On the other hand, the OS mode allows oversampling of the PCM and DSD streams to reach higher frequencies, before digital/analog conversion. The OS PCM mode takes a PCM or DSD stream as input and oversamples it to PCM. The OS DSD mode will take a PCM or DSD stream and oversample it to DSD.Custom PLL circuitThe May DAC features femtosecond clocks and ultra-high performance discrete voltage regulators. It features an advanced custom PLL (Phase Lock Loop) circuit designed for extremely efficient jitter cancellation. Even the highest jitter levels are almost completely suppressed. The Crystek CVHD-957 VCXO clocks in the device are responsible for recovering the digital signal and reclocking it. However, this function can be deactivated, allowing the performance of this system to be observed. A FIFO buffer allows the clock signals to be stored temporarily, making it possible to avoid using ASRC technology, which would have the effect of altering the audio data.SPECIFICATIONSProduct typeDAC R2RInputs1x USB-B2x I2S via HDMI1x Optical Toslink1x AES/EBU1x Coaxial (RCA)1x Coaxial (BNC)Outputs1x Single-ended stereo RCA1x Balanced stereo XLRSupported sampling ratesUSB : PCM up to 32bit 1536kHz, Native DSD up to DSD1024, DSD DoP up to DSD512I2S : PCM up to 32bit 1536kHz, Native DSD up to DSD1024Optical, Coaxial, AES/EBU : PCM up to 24bit 192kHz, DSD DoP up to DSD64THD+N0.00017% @ PCM 48K NOS, 1K (-115dB)0.00025% @ DSD128X, 1K (-112dB)Dynamic range130dB @ PCM 48K NOS115dB @ DSD128XOutput voltageRCA : 2.9Vrms @ PCM 48K NOS, 1.45Vrms @ DSD128XXLR : 5.8Vrms @ PCM 48K NOS, 2.9Vrms @ DSD128XImpedanceRCA : 27?XLR : 54?GENERALSupply voltage220-230V 50/60Hz, fuse type 2A SB 5x20mm110-115V 50/60Hz, fuse type 4A SB 5x20mmConsumption60WHousing materialAluminumDimensionsDAC : 430 x 300 x 55mmPower supply : 430 x 300 x 55mmTotal weight18kgColorBlackPower cable & Remote controlIncluded

I have for sale a gently used and wonderfully functional Denafrips Ares II. It works exactly as designed and sounds great. I will transfer the remainder of the 3 year factory warranty (21 months left) to the new owner by emailing Vinshine (per their process). That way you have piece of mind with your purchase. Denafrips has a service center in Buda, TX should you need to exercise the warranty. I have successfully updated the firmware on this unit twice now. The first time was from the original factory firmware to the 12th Anniversary firmware, then again to a revised version of the 12th Anniversary firmware with improved midrange and bass performance (most recent firmware release). I am only selling this Ares II due to a recent upgrade to a Pontus II. Denafrips DACs are awesome. I am not accepting returns with this DAC as the warranty is only transferable one time. Please be certain of compatibility with your system and your desire for this DAC prior to purchase. There are a multitude of reviews available online describing this DACs performance. This Ares II will arrive in its original factory packaging and double-boxing for safe transit. I always ship within one business day of receiving confirmed payment. International shipping is available via eBays Global Shipping Program only.

You’re purchasing / bidding on the item in the title! Item in original box Over the next month or two, I’ll be listing some nice quality watches, high end headphones and amplifiers. This is not part of my regular listings since I post 90% sports cards and memorabilia under my account. The watches and audio equipment collection are from a MILITARY VETERAN AND CURRENTLY A PRIEST who I consider a friend. His collection was mostly purchased while he spent his time serving our country overseas. As a priest, he does not have the disposable income or time to be able to post these items for sale nor does he have the space to store his collection in his humble living area. This person is very meticulous and “A” type so many of his items were kept in original boxes. Please review any and all pictures for the quality and condition of each item, but if you need more information or pictures; please request through the eBay messaging portal. Also if youre interested in purchasing more than one item, I can combine S&H to try save some money; everything will be based upon weight and designation. Good luck and thanks in advance!!! Disclaimer for AMPS: If unit requires tubes, I dont know how long the tubes have been in storage or last used. Every amp being sold should have tubes included and will be packed with extra care.

PCM63P-Y BURR BROWN R2R DAC update PCM63P-K (2pcs Japan)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 A orchestra 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 (2pcsmade IN JAPAN) meglio di TDA1541A-S2 crown In vendita Dac Cip R2Rdella migliore qualit audio, usati solo su poche apparecchiature professionali,quando le migliori apparecchiature HIFI usavano la versione K inferiore.

Il suono e molto pieno, rotondo, con moltocorpo e bassi pi profondi. come ascoltare unorchestra di classeA contro unorchestra di classe B: la differenza principale che ciascunodegli strumentisti dellorchestra di classe A non solo controlla meglio il suostrumento, ma produce anche la migliore qualit del suono dal propriostrumento. Lo stesso con questa Y: tutto suona semplicemente piricco, c pi risonanza, suona corretto e assolutamente realistico. Il miglioramento dal Kal Y 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 uscitaallaltezza. Il CIP Y statoprodotto in Japan e in Korea, la produzione Japan esibisce un suono pi 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 probabilmente dovuta pi che a selezionipost produzione a differenti qualit 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.

Its a modern DAC/amp solution with a compact footprint and price to match, but with sonics that outperform products many times its size.The HIFIMAN EF400 is a DAC/headphone amplifier that provides great sound quality and will power a wide variety of headphones, reports Gene Hopstetter in his review for Secrets of Home Theater and High Fidelity. Its selling price delivers quite a bit of versatility, and it should be easy to implement within a wide variety of devices with USB output.The HIFIMAN EF4000 is an elegant piece of gear that is simple to use but has a sophisticated sound signature that’s slightly bright tilted, rather neutral, and natural but it punches hard when it has to, notes Louis, headphonics.com, October 19, 2022. Construction is hefty, to say the least, and you will realize that the first time you hold one physically. The front panel has a balanced-looking design that will look good anywhere you place it...Discrete HIMALAYA DACIn 2012, Dr. Fang Bian and his team at HIFIMAN introduced the EF6, the legendary desktop DAC/amplifier that delivers gobs of power and a wide, detailed soundstage. Ten years later, HIFIMAN is proud to introduce the new model EF400, which incorporates the best of recently developed technologies, especially the company’s advanced HIMALAYA R2R DAC.The HIMALAYA is a discrete R2R DAC module that is based on the FPGA algorithm. The combinations of its low audio frequency range, out-of-band noise, and low energy consumption make it a perfect match for high-performance audio equipment. The HIMALAYA DAC module supports the standard PCM music signal transmitted by the most common IIS (Integrated Interface of Sound) audio interface, with a maximum resolution of 24Bit.Fully Balanced DesignThe four-channel differential structure features a DAC, buffer, and active filter that add up to unbeatable fully-balanced output for a Class AB DAC/amplifier. The four-channel fully differential amplifier circuit features a maximum output of 10.7 Vrms on a 36? resistor equivalent load. The result is fully balanced output beyond compare.Oodles of ConnectivityAllowing you to take maximum advantage of the EF400s capabilities is a wealth of connectivity choices. It boasts four front panel headphone outputs consisting of a 6.35mm single-ended, 3.5mm single-ended, 4.4mm balanced, and XLR 4-pin balanced output. The rear panel includes an XLR balanced stereo output pair and an RCA single-ended stereo output pair. Also onboard are USB Type C and USB Type B connections.A four-level front panel control lets you select High Gain NOS (No Oversampling), High Gain OS (Oversampling), Low Gain NOS NOS (No Oversampling), or Low Gain OS NOS (Oversampling) to tailor the output perfectly for your headphones. There is also a high-quality volume control.OverviewSleek, stylish, powerful headphone amp / DACHIMALAYA R2R DAC module4.4WPC outputOxygen-free copper wire wound toroidal transformerLarge 30000uf capacitorsFour headphone outputsTwo USB inputsFour-level gain selector with oversampling / no-oversampling optionsHigh-quality volume controlOutputs6.35mm single-ended headphone out3.5mm single-ended headphone out4.4mm balanced headphone outXLR 4-pin balanced headphone outRCA line outXLR balanced line outInputsUSB Type CUSB Type BSpecs:Signal to Noise Ratio: 118+/-3dB (A Weighted)THD+N (Line out): Between 0.002% and 0.004%Channel Separation: 125+/-3dBMaximum Power Output: 4.4 W per channelDimensions: 8.9” wide. 9.7” deep. 2.4” highWeight: 6.7 lb.
