1/4/2024 0 Comments Sansa disk fuzeOn the actual signal a high frequency sinewave is superimposed. It appears as though Sansa skimped on the analog post filtering. Zooming in on the edges of the waveform revealed something interesting. When examined closely one can see the horizontal lines are slightly sloping downwards in the X3 but NOT in both Sansa’s.īoth scope images are taken from the headphone outputs with a 30Ω resistive load. On the right above the 220Hz squarewave of the FiiO X3. The plot of the Sansa Fuze is exactly the same so see no need to show that one as well. On the left above a -3dB 220Hz squarewave of the Sansa Clip Sport. The pre- and post-ringing that is visible is only seen when steps near the Nyquist frequency (half the sample rate frequency) and, as said, this is NOT the case with real music signals. It should be noted that the test signals used here do NOT exist in nature and certainly not in music. Other interesting plots are made using an oscilloscope and revealed some technical issues with the ‘Sport’ and a bit in the X3.Ī squarewave can show digital- and analog-filter characteristics. SOME of the higher frequency spikes MAY not even be present but could also be caused by the used SB1240 soundcard. This is an indication for low frequency jitter.Īlso the Sansa seems to generate more harmonics and are slightly higher in amplitude. What’s interesting in these plots is the base of thr 1kHz (and uneven harmonics) widens near the noise floor in the Clip Sport. The FiiO X3 seems to be the better player based on specs but they aren’t very far apart. What do the RMAA generated specs have to say about these players (16 bit 48kHz to even the playing field as the X3 is capable of 24-192). Squarewave measurements have shown that the Sansa players run flat from DC (0 Hz) upwards where the X3 rolls off around 20Hz on the HP out but reaches MUCH lower (< 1Hz) on its line-out. this is caused by the soundcard used for these tests (SB1240). No mentionable roll-off in the frequency range… in fact the clip sport is even slightly more linear.įor those that noticed… all 3 players show the exact same amount of gentle roll-off in the lows…. Left plots/data = Sansa Clip Sport Right plots/data = FiiO X3 Some, but far from everything telling, RMAA results for clip sport versus X3 Having read some reviews stating the clip Sport (and clip Zip) have lesser sonic qualities than the older Fuze(+) and Clip(+) I was curious how it measured. lacked definition / presence and the sound was less refined. On direct comparison (same song, about the same volume) when plugging a headphone between them I noticed the clip sounded audibly different (less) compared to the X3. The X3 can play MUCH louder, it can reach 5x the output voltage of the Fuze/Clip in ‘High output’ setting. The Sandisk has a 5 band digital EQ, the X3 has ‘old fashion’ truly analog tone control (bass & treble) + also a 5 band EQ but with a limited dB range (+/-6dB) I have not experienced any issues with the X3 running on 3.4FW though. The 3.4 FW runs fine, I use an alternative ‘theme’ based on 3.4 FW. You need to ensure they are based on the 3.4 Firmware though. The LATEST FIRMWARE for FiiO products can be found HERE.įor those who like other themes there are 3rd party ‘skins/themes’ that can be downloaded. Sometimes the player ‘hung’ and became unresponsive, this IS solved by the 3.3 Firmware.Ĭurrently I have the X3 running on 3.4 Firmware of which FiiO mentioned will be the last FW update for this model.įiiO also added a 5 band equalizer (which I do not use) in the latest firmware. The same is true for the X3, poor GUI, strange button layout, bulky and simple display. The GUI of the clip sport is not the simplest but with properly tagged files (mine are) it works O.K. When loaded with low impedance headphones they measure ‘worse’ in the THD and IMD department.įirst a comparison between Sansa clip sport and FiiO X3: NOTE: these players were NOT loaded with low impedance headphones because I use these players with an external amplifier (Kameleon) The Sansa Clip Sport differs from the Clip ZIP. The Sansa Fuze+ and Clip+ are technically similar and differ from Sansa Fuze (v2) and clip. Sansa Clip Sport, Sansa Fuze v2 (technically similar to Sansa Clip) and FiiO X3.
