Product Comparison: Astell&Kern AK70 vs Fiio X7II
- I have to give a note of appreciation to A&K in that they use varying font sizes to display titles depending on the length of the title. This maximizes the information that is displayed.
- The resolution is actually very nice also! I'm very pleasantly surprised at the quality of the display and the fluid and simple user interface
- The touch screen is bright and easy to use and the interface is similar to my smartphone.
- The information displayed is mostly information about the music file itself and not about the musical content. I want more of the musical content information.
- I find the touch screen hard to use and am not comfortable with the user interface (I don't use anything else with a touch screen) after using the unit 4 hours a day for 15 days.
- A very engulfing sound that maintains a clear, wide soundstage. Hits all the right notes sonically.
- Highs and mids are sublime, and the bass is clean, deep, and punchy.
- I only have 10 gigs of music, so thankfully all my music can fit in the internal storage.
- I was originally attracted to this because of the large storage size as I have well over 1T of files I would like mobile.
- FiiO X7 Mark II is a fantastic DAP! Very easy to operate with just the right controls, great build quality and plenty of storage for your music on the go.
- I absolutely love this DAP, it is compact, light weight, well built, sounds great and is very reasonably priced.
- Small and light. Very good for a portable device in this price range.
- It looks great and I really like the small size. That feels sturdy and has a nice display screen.
- Design wise, this is great, small and curvy. Sound is very good, not a powerhouse but hi-res files sound great.
- The size is beneficial as it easily slides in a pocket or an armband for working out.
- I have ripped all my CDs to FLAC format years ago and put the physical copies away. The AK70 plays any digital file format out there, including Apple Lossless, FLAC and Wave.
- The player has 64gb of internal memory and a slot for a microsd card. I added a 128gb microsd card and the player had no issues recognizing it.
- I was able to play music directly from the nas drive and even copy songs over wifi to the player's internal memory.
- For some reason the AK70 during playback keeps showing a file format/bit rate that does not match my actual audio files (FLAC).
- Poor quality bluetooth.It has no range even when it's right in front of you.Plus in bt mode you lose half volume.
- I like the sound. The unit was quick and easy to setup with beautiful SQ.
- Like other users said, the balanced output is definitely better than the regular 3.5mm output on my se846.
- Music files played with no issues. Also bought some hd tracks and no issues playing.
- Everything worked fine, the user interface is fine, no crash, 2.5mm/3.5mm output no problem, usb dac no problem, bluetooth once paired no problem.
- One of my concerns so far is that the device generates more heat when operating than it should.
- The battery life is great. Just keep the screen off.
- I just hope the battery is as good as everything else. Only time will tell.
- Battery drains fast, I didn't drain it fully but I think it's good for 4 hours, depending on the bit rate and how loud you're going to push it.
- Battery life is not fantastic, but not a deal breaker.
- I give it 4 stars because just because of the battery life.
- Battery life as advertised which is not great but it's the same as others.
- As far as battery life, if you exclusively listen without WiFi , you get about 8 hours.
- Battery life is very good for such a tiny unit, I'm getting about 8 hours and that includes streaming and lots of flac and dsd.
- After 5 and half hours of continuous play the battery just died.
- I found out that the battery when fully charged lasts only 5 hours and half.
