I got my Fiio X3 in the mail today. Luckily, I'm quite ahead on my homework so I have a lot of free time to mess around with this. So here are a few of my thoughts on the player so far:
1. Fiio needs to include documentation on how to properly format cards above 32 GB. One of the Fiio folks said something about choosing not to include it. I don't think that's right. This is important. If you make a player designed for FLAC and only include 8 GB of internal storage, there should be a very detailed section on how to format a large SD card. This isn't very intuitive because Windows does not give you the option to format FAT32 for drives larger than 32 GB. You have to use a third-party program (I used guiformat). I had to do a bit of looking around to figure out how to set things up properly.
Even when I figured out how to get FAT32 format, I chose the wrong allocation unit size thinking I should just go for the largest one (for reference, choose 32768, not 65536). That was wasted time since I had to wipe the drive and re-format although it did give me extra time to charge it. It's not like I was just sitting there waiting for files to upload either.
2. The sound quality is good. Well, duh. Of course, it is, right? It didn't completely blow my mind, but it's noticeably better than my Cowon J3. I currently have the treble set to 0 and the bass set to 3. I like to use portable rigs to mess around with sound signatures on EQ. I do more analytical/neutral listening on my HD 650 + Headroom Desktop Amp. On first listen, I was a little bothered with the bass. After listening for a while, I think it was mostly due to me adjusting to the different sound signature. The Cowon J3 seems to bump up bass...differently than the Fiio X3. I am trying to decide whether to keep bass at 3 or lower it to 2. I like getting in touch with my inner basshead, but only a little bit. It's also that I feel that the Westone 4R has good bass quality, but it lacks a little bit of quantity which is strange since there's two bass drivers.
3. I wish the X3 would read JPG files the same way as the J3 does by making "cover.jpg" automatically the covert art. Now I have to go back and tag all of my files. It's not a big deal in the long run, but I wish it were something I didn't have to deal with.
4. Obviously there was quite a bit of recent discussion on mp3 distortion. With all of the complaints, I thought the issue would have been bad...like Michael Jackson bad. Turns out it's not even Chris Brown bad! I have mostly FLAC files in my X3 with a few mp3 files. Any noticeable decrease in quality compared to FLAC seems to be mostly from the fact that it's a lower quality file. Then again, I haven't done testing with classical music or anything like that. What I'm saying is that it may bother some people, but it's not going to bother everyone.
5. I don't know if it's the lack of tagging in my FLACs or because they're on the SD card, but I don't see them show up on the sort options. This is kind of annoying. I only see the FLAC files that came with the X3. Bob Saget. I'll continue looking around to see if someone figured out how to deal with this already.
6. I listen to quite a bit of Korean music. I saw this brought up already, but I'm confirming that it still exists: Korean characters don't show up when the player is set to English, but they do when it's set to Korean. They just end up being a bunch of blocks.
7. The DAC feature is awesome. I can have the same good sound quality without having to deal with a clunky UI.
I really want to test it with HD 650s, but I'm having issues with one of the drivers so I'll wait. I have a bad feeling that I'm not going to be using my Headroom Desktop Amp anymore.
It's crazy that something this cheap can drive full headphones well. The X3 is almost worth getting for the DAC capability alone.
8. I'm including this because I know it's going give a few of you a good chuckle. The first time I listened to it, I stuck the earphone jack in the line out. lol I'm so used to the Cowon J3 so I was thinking it goes in the same spot. I already saw a few pictures from reviews so I knew there was a separate line out and headphone out. For some reason, I just completely forgot about that. It gave me a good jump when the audio blasted into my ears at high volume. It's like the duh moment you get when you hit your head against a ceiling. Here's a good life lesson, folks: make sure you're sticking it in the right hole. Otherwise, someone might get annoyed.
The Fiio X3 is a good player and I'm glad I bought it, but there's a lot of work to be done. If I were the average consumer, I probably would have torn my hair out from frustration. But that's probably to be expected considering this player appeals to a niche market. I wouldn't recommend this to my non-audiophile friends, but I'm willing to put up with the issues for now.
