Disclaimer: I received the M9 tour unit to evaluate for about 10 days in return for my honest opinion.

Build:

The M9 is small, but solidly built. The controls are conveniently placed. There are two headphone ports, one 3.5mm single-ended (SE) and one 2.5mm balanced (BAL) and a USB port at the bottom of the unit. The 3.5mm port does extra duty as line-out and SPDIF (the 3.5mm TSR to SPDIF RCA adapter is included). The USB port is Type C and operates bidirectionally as USB DAC (using driver software available at https://fiio.com/m9_faq]https://fiio.com/m9_faq[/url]), as a USB data connection, and as the M9 charging port. A USB A to USB C cable is included with the M9. On the left side, there is one slot for a micro SD card (up to 512 GB), a “back[up]/forward[down]” rocker switch for changing tracks, a play/pause button, a volume wheel, and a power/lock button. All other controls are software driven and accessible through the touch screen. Below the touch screen is a LED-enabled “FiiO” logo that, according to the User’s Guide, is blue when the unit is on, pulsing red when the unit is charging, and off when the unit is off. A clear plastic cover is provided to protect all sides of the M9 except the front touch screen that is protected by a pre-installed glass screen protector. The forward/back rocker, play/pause button, and power/lock button are under the plastic cover, but easily used. There are cutouts for the volume wheel and micro SD slot making them easily accessible without removing the cover.

Unlike the X5ii, the SD card actually goes in the “right” side up (IMHO) and it doesn’t go into a tray like the X5iii and X7ii. There is no need for a tray extraction tool.

The rocker bar, play/pause, and power buttons are easy to hit by accident. The rocker bar and play/pause buttons (and the volume wheel) can be disabled during screen-lock using the system settings.

The function of the 3.5mm output port (headphone out [PO], line out [LO], or SPDIF) is controlled in system audio settings. The LO function worked well with my desktop system. By default, the volume control on M9 does not function in LO mode. This can be changed in Settings -> Audio.

Using BAL output and volume 60 into 45 Ohm IEM (WiFi and Bluetooth off), battery life was about 10% per hour. This is consistent with the FiiO claim of 10 hours of play time.

Operation:

Note: I did not test the unit in USB DAC or Bluetooth receiver mode. Nor do I have a NAS or streaming subscription service. My focus was on the use of M9 as a portable audio player.

Touch-Screen:

Once the unit is turned on, a screen swipe is needed to open the main software interface. The same is required when unlocking the screen during operation. There are too many touch-screen operations to describe them all. In general, I found the user interface to be feature-rich, intuitive, and responsive. Some touch-screen operations were finnicky for my large fingers. This was particularly true of the sliders in the equalizer.

Bluetooth:

When trying to perform Bluetooth pairing, the M9 first displayed the MAC address rather than device name. The device name eventually appeared and remained after pairing. I paired with two different Sony WF1000X IEMs and my car audio system.

On first use, there was a lot of static on some tracks when in Bluetooth output mode. This occurred with my WF1000X and in-car system. These same tracks had no static when using headphone ports. Reformatting my SanDisk microSD card as exFAT on a Dell XPS15 laptop did not get rid of the static. FiiO recommended factory reset, which seemed to resolve the problem.

There were some issues with my in-car dash display when connected to the M9. The dash displayed track information (album, artist, track, and total track duration), but the progress indicator stayed at zero and did not advance during play. The play/pause and forward/back controls on the dash display performed as expected.

FiiO Music App:

I first tried the microSD cards previously formatted in my FiiO X5ii. Unlike other FiiO products (X3, X5, and X7), there is no apparent way to format the SD card. The M9 had no trouble reading and scanning SD cards formatted in the X5ii or a Windows 10 computer. Scanning was very fast (less than 10 seconds) for an SD card with about 850 files.

The following file formats were tested and played successfully by the M9:

• .DFF files at DSD128 and DSD64
• .DSF files at 2822k and 5644k
• .FLAC 192kHz 24bit, 96kHz 24bit, 44kHz 24bit, 44kHz 16bit
• .M4A 96kHz 16bit

The M9 did not support the one DSF test file in my library at 11289k.

The FiiO indicator light changes color (apparently at will). I have not been able to determine if the color corresponds to any particular file type, sampling frequency, or bit depth. This behavior is not described in the manual.

The default behavior for the app is to start on a random song after boot. This can be changed in FiiO Music settings to play the last song from the beginning or from the point the song previously stopped.

The M9 remembers separate volume settings for the headphone out (PO) ports and Bluetooth output. Play is paused when inserting or removing plugs from the PO/LO/SPDIF port or when powering on a previously paired Bluetooth receiver.

There are three five-band equalizer settings (Pop, Rock, and User Defined). There is a 6dB gain reduction applied when with EQ enabled to avoid clipping when sliders are max’ed out. I prefer to keep them off. “Pop” and “Rock” settings can also be customized. Gain control for the PO ports is set at the system level (not within the FiiO music app).

Some extended ASCII characters (i.e. those above DEC 127) in album and track names do not appear correctly and may revert to “?” or the Chinese character set when encountered.

Sound:

Sound quality (SQ) was evaluated using wired SE and BAL headphone ports with Low gain, “Short delay Sharp Roll-Off” filter, and “Balance Boost” off.

Heretofore, I have never noticed any difference between SE and BAL output with any other DAP. I did with the M9. There seemed to be better instrument separation and the sound stage was wider and deeper with the BAL output. I have no good way to volume match with the ER4SR, but the benefits of BAL were there for me even with the BAL volume set audibly lower than with SE (and “Balance Boost” off). When using SE output, the separation and sound stage were good and on a par with my X5ii. The BAL output on the M9 took the sound stage to a new level to me.

The frequency response for single-ended (SE) and balanced (BAL) headphone ports was neutral and detailed. That said, I missed the Viper effects available with the X5iii and X7ii.

The M9 amp was adequate to drive my Etymotic ER4SR and Sennheiser HD600 to good listening levels at volumes 60 and 80, respectively.

Overall:

For its size, this is an amazing DAP. The SQ is definitely worth the $300 retail price. I am seriously considering purchasing the M9 for the excellent sound stage with BAL output. It is a notable improvement over my X5ii. My normal listening habit is to select and play through folders on the SD card and I have encountered no problems with the user interface on either the X5iii or X7ii that I previously received for review. That said, the user interface for the M9 seems to be better designed and more responsive than FiiO’s other Android DAPs. The flexibility to format cards on other devices (including Windows 10 computers) is also an advantage. I have grown accustomed to using two SD cards with the X5ii. Nonetheless, the gain in SQ more than makes up for the loss of one SD slot and I would recommend the M9 to anyone in search of a portable DAP.

Setup:
I currently use an iDAC (original) in my desktop configuration. Foobar2000 serves as the source on my laptop (Dell XPS15 [9550]). The signal path is:

laptop USB C -> Dell WD15 “docking station” -> USB 3.0 SS (A) cable to USB 2.0 B in iDAC.

For testing the nano iDSD BL, I used the same USB cable from the dock and added the female to female USB B to USB A adapter that came with the nano iDSD BL. The iFi USB audio driver was updated to version 3.2 prior to testing.

Downstream equipment included home and office desktop setups:
and two headphone/IEM pairs:

The iDAC RCA and nano iDSD BL line-out were used when testing the two desktop speaker configurations (DAC only). The headphone (iDAC) and IEM-match (nano iDSD BL) ports were used when testing the headphone and IEMs (DAC/AMP).

Please note that I did not have am means to connect my portable source (FiiO X5ii) to the nano iDSD BL. All tests used the desktop source noted above.

Operation:
As I am used to the iDAC which only operates on USB power, one of the hardest things for me to remember was to turn the nano iDSD BL off when not in use. Switching between the two was also a bit cumbersome as the iFi USB drivers, while bundled, are different for the iDAC and iDSD. Each switch required that Foobar2000’s output settings be reset. This would not be an issue in normal use.

When using the nano iDSD BL exclusively for several days in my office and home desktop configurations (1 & 2, above) I had to turn the unit on after the computer to keep from running on battery power. This meant that the iFi USB driver would not see the nano iDSD BL at boot time and reverted to my laptop speakers by default. If I was careful (and fast), I could turn the BL on during the boot process (i.e. as soon as the blue charging light came on) and avoid having to unplug and reconnect the unit. I suppose I could have waited for my laptop to boot entirely before connecting the iDSD, but I am too accustomed to plugging the iDAC in first. Old habits die hard.

During desktop use, there were often small clicks when system sounds were played through the speakers. This was never a problem with the iDAC.

Sound Quality:
With HD600 and ER4SR, the nano iDSD BL had cleaner treble and base and better instrument separation and staging than the iDAC. The HD600s and ER4SRs really opened up with the nano iDSD BL. To my ears, both units performed equally (and very) well in the Creek/Epos and JBL settings. I could hear no notable difference between nano iDSD BL and iDAC with these open speaker systems.

Overall:
I was very impressed with the nano iDSD BL when using headphones and IEMs, where there was a clear improvement in sound quality compared with the iDAC. Whether due to a lack of fidelity in my desktop systems, DAC only operation, or the fine job iFi did with the original iDAC, I could not discern a difference between the nano iDSD BL and iDAC with my two open speaker setups. On account of its battery and smaller size, the nano iDSD BL is clearly more portable than the “transportable” iDAC. It would make an excellent addition to a portable rig. For desktop use with open speakers (where battery operation is not important), the iDAC (and likely the iDAC2) might be a better choice in so far as convenience of operation is concerned. The advantage would clearly go to the nano iDSD BL in the “price department”.

Recordings used during the test:
I have very few DSD files in my library and use them only when testing portable gear. I can’t tell much difference between DSD and FLAC for well-recorded source material. The following CD up to studio master quality FLAC files (approximately 500 to 5500 kbps) were used during testing of the nano iDSD BL.

Disclaimer: I received the X7ii tour unit to evaluate for about 10 days in return for my honest opinion.

Build:

The X7ii is solidly built and has a substantial feel. The controls are conveniently placed. Moving the power button to the top near the right side was a big improvement for me (it was on the right side near the top on X5iii). The volume wheel is easy to use and I rarely move it accidently when handling the unit. The play/pause button is easy to use when the screen is asleep. I occasionally skipped forward or backward when picking up the unit or holding the unit and wound up disabling the rocker using custom keylock settings in the system options menu.

The unit came with a plastic case that covers all but the screen, volume wheel, USB, line-out, and 2.5 (balanced) and 3.5mm (single-ended) headphone ports. Small flaps cover the power button, play/pause, and forward/back rocker. My USB charging cable was a bit large and I had to take the case off to use the USB port, but the USB cable that came with the unit does fit with the cover on. There is no way to access the SD slots with the plastic case on.

SD cards are not inserted directly into the X7ii, but must be placed in pop-out trays. A small stylus is provided to facilitate tray removal. The trays could be an advantage or disadvantage depending on how often you switch cards. The cards will fall out of the trays if ejected with the face of the unit up. I strongly suggest turning the unit over when ejecting and replacing SD card trays.

Operation:

I had previously stripping embedded album art from files and including a single file (cover.jpg) in each album subdirectory. The X7ii displayed album art with no problems. My music is structured with directories for each artist and subdirectories for each album. Connecting the X7ii to my laptop (Dell XPS15) was not possible due to an incompatibility previously noted with the X5iii. After formatting two cards in the X7ii, I mounted them on my laptop and copied the library directly to the SD cards. I encountered no problems reading the library from both SD cards. Album, artist, and genre tags functioned as advertised. And a pleasant surprise, within artist, albums and tracks were sorted properly by track number (not by name as with the original firmware in the X5iii).

Most of my files are in FLAC format, but the X7ii had no problems with the few 64 and 128 bit DSD (DFF and DSF format) and ALAC (*.m4a) files that I threw at it. The only exception was 11289k DSF file in the 2L Test Bench set (see below). The 2282k and 5644k versions of the same recording worked flawlessly.

The FiiO music app is feature-rich and the learning curve was not too steep. I activated WiFi to enable some Viper effects and tested Bluetooth connectivity with my Sony WF-1000X earphones. Both worked well, but I kept them off most of the time to increase the battery life which was quite good for an Android device. I almost liked the battery information in the Android setup, until I realized that the battery usage accounted for only totaled 40% of what was used. There are clearly some categories missing from the battery menu (i.e. power drawn by AM3A). With 53% battery left, the utility estimated ~4h left leading me to believe that 8h is a reasonable expectation for battery life. In standby mode (i.e. no music playing), the battery went from 80% to 40% over the course of about 10h. The 2.0A charger for my Android phone worked fine to charge the X7ii (40% to 100% in just over 90min).

As alluded to earlier, the only major problem I encountered was the known incompatibility of X7ii with the USB ports on my Dell XPS15 (9550) laptop. This issue have been noted before for the X5iii and I had to load music on the SD cards on my computer. I did not install and test the Windows 10 driver for the X7ii because of the USB compatibility problem (and I have a desktop DAC and would never use the X7ii in DAC mode).

Sound:

The X7ii has lots of detail without being fatiguing. The sound stage is wider than my X5ii and the instrument separation is outstanding with well mastered source material. The X7ii/AM3A drives my Etymotic ER4SR with authority both single-ended (SE) and balanced. Apart from the need to reduce the volume with the balanced cable, I could not tell much, if any, difference in the two headphone outputs. The AM3A (SE) had a more difficult time driving my HD600s, but full volume (120) was well above my tolerable listening level. Where volumes from 45 to 55 were good for my ER4SR (SE), the HD600s required 90 to 100 to achieve the same volume (slightly higher when EQ was turned on. There is a -6dB gain reduction applied when with EQ enabled to avoid clipping when sliders are max’ed out.

I tried several of the free Viper effects. The one I found most useful was the Playback Gain. It takes a few moments to analyze the source, but does an adequate job of adjusting volume on different albums/tracks. It may not be quite as effective as embedded replay gain, but it served the function with only minor volume adjustments between loud and soft tracks. Viper Playback Gain reduced the need for excessive volume fiddling on ER4SR and HD600. I paid the $0.49 to enable the Viper Bass and found that I quite liked the “Natural Bass” setting as it had minimal impact on the mids and highs.

Connected to my Creek 4330SE amp and Epos M2 speakers, the line-out on the X7ii was not as transparent (almost muddy) compared to my computer with Foobar 2000 and USB to iDAC. This was surprising since the X7ii/AM3A/ER4SR (and HD600) combo was on a par with (or slightly better resolved) than my computer setup.

Overall:

This is an amazing DAP. The SQ is definitely worth the $650 retail price. I could do without Android and all the battery wasting overhead, but the SQ and FiiO music app are worth it. This would be my first choice for a DAP if not for the fact that I already have the X5ii, a very fine DAP in its own right. The X7ii is notably better, but I can’t quite convince myself (or my wife )that it is worth the price to upgrade.

Disclaimer: I received the X5iii tour unit to evaluate for 7 days in return for my honest opinion.

Build:

The X5iii is solidly built and has a substantial feel. The controls are conveniently placed with the exception of the forward/backward rocker. I frequently skipped forward or backward when picking up the unit or holding the unit in my left hand and pressing the power button to wake the screen during playback (the base of my thumb would activate the rocker when pressing the power button with my index finger). The rocker can be disabled using custom keylock settings in the system options menu.
The unit came with a plastic case that covers all but the screen, volume wheel, and 3.5mm headphone port. Small flaps cover the 2.5mm balanced, line-out, and USB ports. The flap on the USB port would not stay in the closed position. The plastic cover must be removed for access to the SD slots. I assume it’s from repeated charging with the cover on.
SD cards are not inserted directly into the X5iii, but must be placed in pop-out trays. A small stylus is provided to facilitate tray removal. The trays could be an advantage or disadvantage depending on how often you switch cards. The cards will fall out of the trays if ejected with the face of the unit up. I strongly suggest turning the unit over when ejecting and replacing SD card trays.

Operation:

I had prepared my music library in anticipation of receiving the tour unit, stripping embedded album art from files and including a single file (cover.jpg) in each album subdirectory. My music is structured with directories for each artist and subdirectories for each album. After formatting the cards in the X5iii, I mounted them on my laptop and copied the library directly to the SD cards. I encountered no problems reading the library from both SD cards. Album, artist, and genre tags functioned as advertised. Unfortunately, tracks sorted within artist without regard to album doesn’t make any sense to me. I’ll stick with playing by folder.
Most of my files are in FLAC format, but the X5iii had no problems with the few 64 and 128 bit DSD and ALAC (*.m4a) files that I threw at it.
The FiiO music app is feature-rich. Almost every time I touched the screen I found a new feature. I have no need for WiFi or Bluetooth connectivity. Consequently, the battery life was quite reasonable for an Android device. In standby mode (i.e. no music playing), the battery went from 80% to 40% over the course of about 10h. The 2.0A charger for my Android phone worked fine to charge the X5iii (0% to 100% in a couple of hours).
The only major problem I encountered was the known incompatibility of X5iii with the USB ports on my Dell XPS15 (9550) laptop. When connecting to an USB3 port on a XPS 15, the unit keeps cycling through the welcome screen. This happened whether the USB3 port was on the computer or a connected Dell WD15 dock. The same behavior was not noted on the USB3 port of the Dell DA200 attached to the same laptop, but an error message was generated, “Windows has stopped this device because it has reported problems. (Code 43). A request for the USB configuration descriptor failed.” The X5iii was powered down in all cases. USB storage mode would not work either when the X5iii was on. I had not installed the Windows 10 driver for the X5iii since I have a desktop DAC and would not use the X5iii for this purpose.

Sound:

The X5iii has lots of detail without being fatiguing. The sound stage is wider than my X5ii and the instrument separation is outstanding with well mastered source material.
The X5iii drives my Etymotic ER4SR with authority. I tried the line-out with my FiiO E12 amp, but found that it was (almost) completely unnecessary with ER4SR. The only exception was the analog bass boost on the E12. I fiddled with the digital EQ (FiiO music and Viper), but neither compared with the instant gratification of the E12 bass boost.
I tried several of the free Viper effects. The one I found most useful was the Playback Gain. It takes a few moments to analyze the source, but does an adequate job of adjusting volume on different albums/tracks. It may not be quite as effective as embedded replay gain, but it served the function with only minor volume adjustments between loud and soft tracks.

Overall:

This is an amazing DAP. The SQ is definitely worth the $399 retail price. I could do without Android and all the battery wasting overhead, but the SQ is worth it.
