FiiO K7 Full Balanced HiFi DAC Headphone Amplifier AK4493S*2, XMOS XU208 PCM384kHz DSD256,USB/Optical/Coaxial/RCA Inputs, 6.35mm/4.4mm Output

Being a balanced amplifier, it provides a lot of power and can easily drive any headphones and/or IEMs you throw at it. I've been driving my HD660S2 pretty easily with this. The volume knob is non-linear. I haven't studied it too closely, but I'd say it's logarithmic. That means you'll get very low volume upto about 11'o'clock position. After that, the volume grows much faster. Overall, loudness is not a problem at all. I keep the volume at a little west of 12 o clock. For some reason, Amazon India is showing an extremely inflated price of 44k (against an MRP of 59k). I bought this new with warranty from headphonezone.in for about 19k (against MRP of 22k). Not sure why or how the MRP itself is blown up on Amazon. For that price one can get a Schiit Magni Modi stack, which is a higher class of DAC and AMP. Bottom line, if you buy this (check prices on different sites, first), you'd likely never need another DAC/AMP. It's built like a tank and has plenty of power on tap for anything you throw at it.

Teknik detaylara girecek kadar bilgiye sahip değilim ama iyi bir müzik dinleyicisi olarak şunu diyebilirim ki Sennheiser 660s2 yi Fiio K7'de 4.4 mm dengeli giriş ile kullanmaya başladım. Daha önce İfi Zen Air Dac kullanıyordum çok kötü diyemem bu DAC için ama Fiio K7 kullanmaya başladıktan sonra kulaklık resmen 2-3 level atladı diyebilirim. Geniş sahne ve enstürman detayları büyük ölçüde arttı. Ayrıca kulak tırmalayan müzikler netleşti ve berraklaştı. Daha zevkle ve keyifle müzik dinliyorum.

DAC&AMP combo muy interesante. Fácil de usar. Entradas de 6,3 y 4,4mm. Sonido del DAC neutro sin color. Amplificación de sobra para cualquier auricular (excepto para los STAX). Peso liviano. Tamaño bastante reducido. La verdad que si no tienes uno y si tienes auriculares es una buena inversión. El sonido mejora evidentemente entre esto frente a un pc/movil pero mejora aún más si tienes auriculares demandantes como planares o de alta impedancia al tener una salida balanceada de 2000mw a 32 ohmios, lo cuál, a este tamaño, peso y precio es una locura. Lo recomiendo sin duda. A la artesanía y el sabor le puse una estrella.

Amplificador muito bom. Som muito limpo sem ruidos e faz qualquer fone tocar 4x mais alto. Top.

Set up: Pc>Usb Dock>Fiio K7>HifiMan Arya Stealths Where do I start? Though this does add some warmth to my aryas, it balances out the 8k peak to the point where its enjoyable to listen to. Other clearer dac/amps, like the dx3 pro+, only compounded to the issue, making me return them. Not only does it add warmth, its extremely smooth and spaces out the instruments more, alowing it to feel open rather than congested, which was another issue with the dx3. Sounds also echo out as it should rather than being abruptly cut off, adding to the sound stage. Power wise, my Aryas can sound loud, and evening deafening if need be. Iems even more. If you need a nuclear reactor as an amp though, go for something else, and something most definitely more expensive. Its more lifelike/closer to what the music would sound in person like than the clinical presentation of the dx3. Because of this though, some details are drowned out. (Note that my opinions might differ and you might actually like the dx3's sound signature.) The caveats to this dac/amp is that there is no filter options and there some static when it is on high gain and there is nothing playing. Its not audible on sensible volumes, and only slightly audible on ear splitting volume. Another thing is the analog knob. It kinda sucks, as it doesn't follow a linear path, where it steadily goes from 1 to 100. Its actually logarithmic, where 7-10 oclock is barely audible (1-15 vol), 10-12 is medium (15-40 vol), and 12 - 3 is loud (40-90 vol). 3 to 5 is deafening (90-100 vol). Perhaps this is with iems in mind as they require a lot less power, but I find the dx3's infinitely spinning digital knob to be much more fun to play with. Anyways, This thing makes my aryas sound like a beast, where every other dac/amp ive tried gave me a headache. If you're on a budget and looking for something to power your Aryas, or anything similar, go with the K7. Oh yeah. It also comes with a 3.5mm to 6.35mm adapter. Instant 5 stars.

Gebruik deze dac versterker met de Hifiman xs. Dat is goed, maar koop er een gebalanceerde kabel bij en dezelfde koptelefoon wordt beangstigend goed. Geen reden om meer geld uit te geven voor audiofiel plezier...
