Review: I am gobsmacked at how good this is. - Man, have I had an interesting journey with headphone dac/amps. I started off with typical sound cards in computers. Going back to the 90's. Sound Blaster being the go to brand because they were simply the best back when. In the late 2000's early 2010s I moved on to an off brand called HT OMEGA which had this dope sound card called the Claro Halo and my god was a difference. At the time it was one of the best cards youc could get. Sadly its old school PCI and modern motherboard have nicked PCI from the board. Now its all PCI-Express.... And then in the most recent years I was using the Sound Blaster ZXR which was a mint little kit considering what was available for PC at that time. Then later I upgraded to the Sound Blaster AE-9 and was EXTREMELY disappointed. There were so many issues I don't even feel like going into it here. But eventually I started getting to dac/amp combos. I first went for just a headphone amplifier. At the time I was using a Schiit Magni 3 connected to my AE-9 via the RCA. But the audio was off, because of how the card was handling it. Instead of "side left/side right" like headphones would be, it was forward facing, so it was front left/front right which meant in games, I literally could not hear behind me. Such a poor design from SB. I wouldn't really "notice" that issue until the next upgrade. From there moved to a Schiit Magni 3 Heresy for the higher fidelity over the original. And yeah, it sounded better. Not a huge improvement, but enough that I could tell. Both products had volume pot failures. Meaning they got super scratchy. Hated it. After that I went for the Topping DX7 PRO. Man what a brilliant little dac/amp. Sadly my right ear went out after about a year of use. And Topping refuses to warranty it because I changed out the OP-AMPS. Why have OP-AMPS that you can change if that ends the warranty. It's literally like plugging in a headphone.... I know damn well they can't deny warranty, but I don't feel like lawyering up for a CHINESE company. They offered to sell me a new "motherboard" for $350 and it's like, if I am gonna spend money, might as well move on. Long story short, I won't buy Topping ever again.... and I will continue to tell others not to as well. Their loss. Never screw over your customers.... Then I bought this mad house. The FiiO K9 Pro ESS edition. AND MAN. What a difference in sound. It is literally above and beyond anything I have ever heard. I am running this huge heavyweight (it's literally heavy and quite large compared to my Topping DX7PRO) with my Sony MDR-Z1M2 headphones via 4.4 pentaconn (aka balanced). Man I love the sound signature. Right away you can tell the difference. The bass is cleaner and deeper, the treble is nicer, and the mid range like vocals, pure extacy. Anyway, I haven't had any complaints using this new monster. Well worth the money. I honestly think they should make a cheaper "gamer" edition where it's basically JUST USB input, and then 6.35 or 4.4 output. XLR is a waste of time and money. YEAH I get there are tons of headphones on the market that support it, but you can easily get an XLR to 4.4. The 4.4 pentaconn connection is just the superior connection. No need for bluetooth or other outputs. By having less but still having the same quality, they could bring the price down. Maybe call it the K8. If they can figure out how to bring this quality down a few hundred dollars, they could take over the gaming market easily. At least that is my opinion. Anyway I have tested so many different musical genres'. From house/dubpstep/trance to country to metal to rock to classic rock to jazz to classical to oldies. I mean I have gone through it all. And I can't find any faults. In fact I find I am appreciating music more thanks to the K9. In fact, even when playing video games im hearing little details I never heard before. It's just that accurate. I cannot complain. I can't wait to listen to more music. I am just enjoying music that much more thanks to the quality.

Entonces vi que el AMP y DAC de Sennheiser tiene un chip ESS9028PRO, el cual es un Chip excelente ya que se usa para tener teatros en casa, ya que procesa hasta 8 canales en un solo chip, entonces para unos audifonos que solo tienen dos canales, ya es un exceso. El problema del AMP DAC de Sennheiser es que cuesta al menos 3 mil dolares y no hay muchas reseñas y en las que puse encontrar parecía que por dentro era más un buen poyecto casero de electronica que un procesador de audio de alta gama. Entonces cualquier audiofilo sabe que Fiio siempre es la marca que da más por tu dinero y en principios de año lanzó un DAC de alta gama para audiofilos, yo anteirormente tenia un K5Pro el cual si es muy bueno pero no superior al Monolith. Entonces resulta que el Fiio K9 tiene dos procesadores ESS9038PRO en lugar de uno de ESS9028PRO que tiene el de Sennheiser, y que el chip de amplificación es el más reciente de THX, por lo que en la pura ficha técnica ya es un mejor equipo, si a eso le agregamos que la circuitería es echa de manera automatizada con componentes de la más alta calidad; que además cuesta menos de la mitad y que Fiio es el campeón de prestaciones en su rango de precio, incluso a veces más que Schiit; tenemos en frente al campeón de los AMP DAC (claro sin meternos a lo exótico). Yo pagué mil dolares por el K9PROESS y otros 1500 por los HD800s, la verdad es mucho dinero; pero bueno es una gran experiencia de Audio, todas las canciones son mejores, los juegos en la parte sonora son mucho, mucho mejores; Probé todos mis audífonos con el K9PROESS y con todos noté una gran mejoría respecto al AMP DAC Monolith que tenía antes; Usé unos AKG K702, Vmoda M100, AT M50x, Sony XB500, HifiMan HE400s, BeyerDynamic DT990Pro y varios de Sennheiser HD599, HD598cs, HD660s y los HD800s. Y la conclusión es que es mejor tener buen AMP DAC que tener buenos audífonos. Tristemente, me falló a los 4 meses de hacer la compra, al ser compra en Amazon ellos se hicieron cargo de la devolución la cual fue bastante rápida y sencilla. ## Frequently Bought Together - FiiO K9Pro Amplifier Headphone Amps Bluetooth High Resolution Desktop Portable Support Lossless Sound 384kHz/DSD256/MQA/LDAC/AptX Adaptive/AptX HD for PC/Speaker/Home Aduio(K9Pro ESS) - Sennheiser HD 800 S Over-the-Ear Audiophile Reference Headphones - Ring Radiator Drivers With Open-Back Earcups, Includes Balanced Cable, 2-Year Warranty (Black) - Sennheiser Genuine Adapter Cable Female 1/4" 6.3mm to Male 1/8" 3.5mm Plug for Headphones --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/752784294-k9pro-amplifier-headphone-amps-bluetooth-high-resolution-desktop-portable-support](https://www.desertcart.ph/products/752784294-k9pro-amplifier-headphone-amps-bluetooth-high-resolution-desktop-portable-support) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-07-26*
