HIFIMAN is especially known for its critically-acclaimed Planar-Magnetic headphones that feature state-of-the-art driver technology. The company also designs and manufactures world-class dynamic in-ear drivers which have also garnered awards and rave reviews Massive Power and Superior Soundfrom a Sleek and Stylish Chassis The Modern Desktop DAC/Amp Solution-Compact yet Powerful Award-winning HIFIMAN HIMALAYA R2R DAC Full Balance Output Specifications： Maximum Power Output: 4.4 W per channel Dimensions: 246.5mm(L)x228mm(W)x61mm(H) Weight: 3.08kg The Modern Desktop DAC/Amp Solution Compact but with sonics that outperform products many times its size In 2012, Dr. Fang Bian and his team at HIFIMAN introduced the EF6, the legendary desktop DAC/amplifier that delivers gobs of power for a wide detailed soundstage. Ten years later, HIFIMAN is proud to introduce a new model, EF400, that incorporates the best of recently developed technologies, especially the company's advanced HIMALAYA R2R DAC. Review: Super dac - Dac de très bonne qualité qui améliore le son d enceintes trop analytiques par exemple Review: パワフルで自然なサウンド。かなり良いです。 - 【外観】 写真だとシンプルな外観ゆえにチープな印象を受けましたが、手に取ってみると非常に剛性があるので、高級感が感じられます。また、ボリュームノブは発売当初の海外レビューだと「軽すぎる」と指摘されていましたが、その後改善されたのか個体差かは判りませんが、それなりに重たさを感じられ回し心地は良かったです。 【音の感想】 全体的にパワフルでありつつも、空間表現や音の聞こえ方が自然です。 以下、帯域ごとの感想 ・高音 マイルドでとにかく嫌な音を出さない音造り。特筆して良いとかは無いけど自然に伸びる感じ。 ・中音 ボーカルは少し奥に自然に定位している。にも関わらず、声の線が太い為、厚みたっぷりで聞かせてくれる。全体的に艷やかで生々しく、聴き応えがある。 ・低音 厚みと深みあって、ほどよいパンチ。それでいて他の帯域を邪魔しない絶妙なバランス。イヤホンで聴いてもヘッドホンのような立体的な低音を出してくれる。キレよりは余韻重視で丁寧に広がる感じが病みつきになりそう。 ・音場 かなり広い。薄っぺらく広げた感じではなく、広大な音場の中で濃厚な音が鳴っている。 高感度のイヤホンでもホワイトノイズはありませんでした。今のところ満足感は非常に高いです。 ## Features - Massive power and superior sound from a sleek and stylish chassis: The EF400 is the modern desktop DAC/Amp solution, with a compact footprint and price to match, but with sonics that outperform products many times its size. Ultra-high efficiency and low power consumption at maximum stability:4.4W per channel balance output. Embedded with HIFIMAN HIMALAYA R2R DAC- Recipient of 2022 VGP Gold Technology Award (Japan). - Experience the prized performance of the R2R DAC: HIMALAYA is a discrete R2R DAC (digital-to-analog) 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 - Full Balance: The four-channel differential structure features a DAC, buffer and active filter that add up to unbeatable fully balanced output for stunning performance from a Class AB DAC/amplifier. The four-channel fully differential amplifier circuit features a maximum output of 10.7 Vrms (THD<1%) on a 36Ω resistor equivalent load. The result: fully balanced output that is beyond compare. - 4-level Function Switch: High Gain NOS, High Gain OS, Low Gain OS, Low Gain NOS ★Headphone Out (Front Panel): 6.35mm Single-ended; 3.5mm Single-ended; 4.4mm Balanced; XLR 4-Pin Balanced Output. ★Line Out (Rear Panel): CANNON Balanced Output; RCA (Single-ended).★ Input: USB Type C; USB-B - 220v ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B1MGWGKZ | | Brand Name | HIFIMAN | | Country of Origin | USA | | Customer Reviews | 4.3 out of 5 stars 90 Reviews | | Global Trade Identification Number | 06925624202408 | | Importer Contact Information | Hifiman Electronics India Pvt.

Because Dr Bian's decoding arrays are inherently very accurate, they don't benefit much from oversampling unless the digital source is very poor and by not oversampling, its analog output has no sonic artifacts left over from an oversampling stage that must be filtered away. So I think that the himalaya's oversampling mode is very low like 2 or 4X - HiFiman doesn't disclose their sampling rates, but it doesn't matter - unlike delta-sigma DACs, that must oversample to minimize the distortions inherent in their D->A conversion and the digital filtering required to reduce them to acceptable levels - R2R DACs oversample to increase their conversion accuracy and dynamic range and require little or no post-processing of their analog output. I've had this EF400 for about a year, and its been flawless, it drives power-hungry planars like HiFiman Edition XS, or Monoprice M1070 with control, authority, and revealing detail. Conversely, switch to its low-output range, and sensitive dynamic headphones like the HiFiman HE-R9, or Harmonicdyne Poseidons are presented against an utterly 'black,' noiseless background. Yeah, 500 dollars is a pretty stiff hit "Just to listen to headphones..." but I believe that the EF400 is pretty much the end game for any setup costing less than six figures. Cheers Jim **Q: can it be used as preamp fot active speakers and control the volume from both?** A: No. The rca jacks are fixed volume and the volume knob on the front only controls the headphone jacks. **Q: does this dac/amp works with Playstation 5?** A: As long as your PS5 has a USB out, which I think it does, the amp should work. The EF-400 only takes USB-B or USB-C, no optical or USB-A. So be aware of that. **Q: Will this power the Hedd Heddphone or any other hard to power Headphone with enough power?** A: I think it has enough power for planar. However, it may not listened good for some headphones, such as LCD-X.

I will admit I purchased a refurbished one and it was in excellent condition so I saved a couple hundred bucks. Thanks Amazon. If you have hifiman planars this amp is for you. That R2R dac along with descrete amp is a stunning. My Ayra organics sound unbelievable. These things are known for brightness and not in a good way but the pairing here is straight from heaven.
