I did some audio tests on Ainol V9000HDA sample. The player has 9 preset EQ settings. Nature, DBB, Pop, Rock, Classic, Jazz, Vocal, Dance and Soft. Unfortunately four of the nine presets proved useless. Using these four presets sound was not just bad but very nasty. In the headphones could be heard crackling and wheezing noise. No, I did not listen to songs on the full volume. Headphones also are not torn or broken. I used MP3 320kbps and FLAC music file formats in V9000HDA audio quality test. My impressions are described below.
* Nature -- Yes, acceptable, good sound, 4.8 out of 5
* DBB -- NO, Dull, with pronounced bass and crackling sound. 0 out of 5
* Pop -- NO, crackling sound, 0 out of 5
* Rock -- Yes, acceptable, good sound, with the Hall effect. 4 out of 5
* Classic -- NO, crackling sound is noticeble but less then on DBB, Pop and Jazz, 1 out of 5
* Jazz -- NO, crackling sound, 0 out of 5
* Vocal -- Yes, acceptable, good sound, 4.5 out of 5
* Dance -- Yes, very good sound, as good as on Teclast T51 with "Normal" EQ settings. 5 out of 5.
* Soft -- Yes, very good sound, as good as Dance preset. 4.9 out of 5
I was very surprised when I heard the sound quality, with a "Dance" preset on the V9000HDA. It was very close to the "Normal" preset on the Teclast T51. The difference was felt only in a slightly narrower range compared to the T51. On the T51 sound is more extensive and complete. This means that the audio chip in the Ainol V9000HDA is not bad. The main challenge for Ainol developers is to properly utilize chipset features. This is good news for those who put their eyes on Ainol V9000HDx line.
But note that this is just my personal observation. Results may vary depending on your experience and musical abilities.
