Review: Good 1st Step onto HI-FI - l'm an audiophile who knows there is A LOT of snake oil in this business. A LOT. Now, having said that, the k7 deserves the $200 asking price. If you have a good sound-card, the k7 will be a mild improvement, but sure enough an audible improvement. Don't expect night and day differences, but you'll find some. Whether you like the new sound signature more than your sound-card, that's another story. The k7 will offer slightly more refined sound, but similar 'technicalities.' Where the k7 is a real upgrade is in having a dedicated volume control knob. The volume is digital so the knob has no end to it (you can keep on spinning it once it has reached its max). My unit didn't have a very noticeable delay (as some reviewers stated). Perhaps that has to do with how powerful/fast your computer is (?). Some people also find the volume odd because for the first (almost) 1/4 of it, you don't hear anything (on less sensible HPs). Fiio engineers did this on purpose: this way, users of very sensitive IEMs will not have a problem adjusting the volume to their preferred level. The k7 (unlike any sound-card that l'm aware of) offers balanced connections so you can give that a try. Personally, l did hear the difference. My HPs did open up with the balanced inputs (4.4mm and 4pin XLR). If you've been into this hobby for a while (if your brained has been trained to notice these sound nuances), you'll notice that right away. Then there's the extra power in case you need it. Some people may prefer to keep their sound-card over the k7 in favor of having more 'desktop free space.' l get that. Personally, l have a volume ring on my keyboard, but l much prefer having a knob. Besides, it's easier to plug/switch HPs from the k7 (likely placed on your desk near your mouse) than from the back of the PC, under the desk. Does the k7 get hot? Not at all (room temperature 80ºF). *Now, let's address the elephant in the room: the Fiio k9 ESS* I guess the AKM version is equally good too, but l haven't tested that one so my words will refer to the k9 ESS (non-pro). If you wonder, I didn't want a slower pace sounding device, that's why I was only interested in the ESS version. k7 VS k9 ESS: The difference between the k7 and the k9 ESS aren't mild or subtle, but very significant. We're talking about a product (k7) that has its own sound signature (warmer, slower, more bass where there shouldn't be, small soundstage), but that plays on the budget league VS a product (k9 ESS) that plays in the HI-FI realm. The k9 will be a noticeably improvement in the soundstage, dynamics, clarity and rest of the audio attributes. Example: on the k7 the HD800s treble is harsh; plug them to the k9 and the treble becomes oh so beautiful. Mind you, k9 ESS is 'fast.' The music will play faster than on the AKM which has the 'normal pace' tunning. You may like a faster pace more or less, but you'll certainly notice the difference in speed. This is supposed to be an attribute of the ESS chips (regardless of the system implementation). Have you ever heard people saying something like, "buy the best HP you can then spend the rest on a DAC-amp?" Nonsense. Once you have a good pair of HPs ($300-$500), trust me, they will sound noticeably different when paired to the k7 VS the k9. Example: You'd think my old, yet great sounding Hifiman HE-400 (non s, etc. just plain 'HE-400') sound great when connected to the k7 and also my sound-card. Now, plug them to the k9 ESS and let me read your mind: "Holly guacamole! Now we're talking business." Yes, those are your own words ;-) If my budget was $1000, l'd rather get a k9 ESS and a $300-500 HPs than spending $200 on the k7 then $800 on a HP. Even better, l'd buy the k9 ESS new (to test it for yourself in case you want to return it, and to have the always SO important WARRANTY just in case) then spend the rest of the budget on a 'second hand' headphone (in good condition with replaceable earpads). Amplifiers come defective even when new (l've already sent 2 back, the very k9 ESS l'm talking about which had a defective 'optical in' and a k9 ESS Pro), however headphones rarely fail (although they also do it seems; it never happened to me). l know l digressed quite a bit, but l hope you enjoyed my 'on the fly, all over the place' review of the Fiio k7. Remember: "Buying cheap is expensive" or the German version "We're too poor to buy cheap." Save for the k9 ESS, buy it new (return, warranty), enjoy it for years to come. Hope this helps!
Review: It actually works! - I bought this to adequately power my Semnheiser HD6xx. My laptop was doing a good job of getting them to a high volume, but I noticed a bit of mud in the bass especially and it felt compressed overall. Pros 1. Powerful enough to power them with high gain and single ended. Granted, I gotta turn it to about 3pm on the dial to do it but my source (laptop) isn't entirely maxed out so that's on me. 2. Doesn't get too warm. I listened to them for an entire work day, with a lot 0 minute break for lunch, and it was warm to the touch, but not concerningly so in the slightest. 3. Worked easy for me. Downloaded and installed the FiiO driver, plugged in the USB cable, and it immediately worked. 4. I personally prefer AKM DACs like this to ESS DACs. ESS are more accurate, but the way AKMs do it pretty smooth and that pairs well with the Sennheiser HD6xx. 5. Came with everything I needed in the box, including a 3.5mm-to-quarter inch adapter. No extra purchases needed. 6. Titanium is a nice color, and works well with the light around the volume knob. Looks nice on the desk. 7. I see what folks mean about the delay when using the volume knob, but my adjustments are usually slight and the lag doesn't bother me. The dial feels good to turn. 8. Snagged it used for $200 after tax. Neutral 1. As is the nature of these things, the improvement is different from song to song depending on the song, how it's mastered, and how dense it is musically. I got the biggest improvements from dense stuff like classical and metal, but far fewer improvements from simpler songs with fewer instruments. So, whether or not it's worth a $200 purchase depends heavily on what you listen to, and what volume, and what you were using previously to power your headphones, AND the impedance/sensitivity of those headphones or earbuds. 2. It's making me want a balanced cable to take full advantage of tbsoe THC amps. Cons 1. Since the noticeable improvement is only about 5-15% on average depending on the song, there is a performance vs value question that I'm not sure how to answer. It DOES work, at least for these high impedance Semnheisers, and there is a tangible difference you can hear with proper a/B testing. So, these get 5 stars for doing what they say they're gonna do. However, good amp/DACs like this are transparent so my headphone sounds the same just with less clipping, better bass control, and more instrument separation, but whether or not that's worth $200, is tough to answer. Overall, I'm just grateful that this isn't audiophile snake oil, which is exceedingly common in this space unfortunately. My headphones sound cleaner (at higher volumes too), and like the drivers are finally getting enough power. The AKM DAC is smooth and inoffensive, and the fact that I can get even more power with a balanced cable is a nice "someday upgrade." Is the sound quality $200 better? Hard to say, but definitely greater than $0 better, so in all, yay!

### ⭐⭐⭐⭐⭐ Amazing AMP/DAC for the value, quality audio.
*by I***R on June 17, 2023*

I am not an audio "expert" in any way, and I am an audiophile newcomer, but I must say that after powering my HD 600s with these, there is so much "room" for the music to expand itself, without any distortion or cluttering of the audio. The USB connector is a type B to A which is fine for me, but others may prefer it being a type C. The build quality of this AMP/DAC is amazing, it is built entirely from aluminum with CNC finishing, and everything else like the volume knob, switches and buttons just feel expensive. Nothing feels cheap, and it is a sturdy compact, little unit. The volume knob acts, obviously, as a volume knob but also as an on/off switch. Switching between on and off gives a nice, satisfying click, and when turning the unit on there's a subtle RGB coloring show going on, which switches to a solid color which isn't too bright, depending on your music's sampling rate. Blue: 44.1KHz/48KHz, yellow: 88.2/96/176.4/192/352.8/384KHz, and green: DSD64/128/256. In terms of power, there's really nothing these couldn't power. You have enough power for any headphone you'll plug in, which is great. The gain switch works well, and doesn't cause any distortions when setting it to high. A balanced feature at this price range, from what I've seen, is super RARE, which means you have incredible value for money, making this a future-proof AMP/DAC. You have guards in place to protect your headphones and your ears, as well as unit protection. The volume knob takes a second to adjust, since it has a guard against sudden, accidental high volumes. If you're looking for an AMP/DAC combo, this is the one to go for!
