product description

 

   When the title and "HIFI" detached, Susan can not help but burst throbbing purple cool, Jun listen to small to do a big issue.

   Purple Shan Tsai likes to listen to her sing,
   Touch it to make it good to go.
   Penny likes, listen to her sing,
   I am cool weather here, there yet.
   Cheer like, I listen to her sing,
   I use real fabricated a lie, but also I guess this broken world.
   That hold guitar girls, is a kind of charm.
   Like Avril children, listening to her sing,
   Feel calm I belong I\'m so happy here.
   Like Hsiao, listen to him sing,
   My Princess, I want to occupy your beauty.
   Like rock,
   To soared to soared to burst, continuous orgasm.
   Immortal youth, rock to old!
    ......

 

    so, purple Shan has been looking to make their own moving mobile sources, it is nothing more than a few good online reputation, more or less not very suitable taste.
   Purple coral itself is 1/8 so-called R & D engineers, so the initiation of an idea of their own hardware and software last year, the process ignored.
   To speak of this without the appearance of individual catch the foot rub a little "lossless portable audio players," summed up the following disadvantages:
   1. Shell is not perfect, some headphone jack position offset portion of the housing has a small touch knock, and Virgo perfectionist, please pass.

   2. There are very few might crash. (Press the reset button to reset to the crash, purple coral will frequently update the firmware)
   3. endurance capacity needs to be strengthened. (2850mAh battery, 8 hours)

   4. heat while charging while listening to a little big

   5. Using a small volume potentiometer is a common problem when unbalanced left and right channels
   and so on ...

 

   And then, and then there are then, the machine still has some advantages.
   1. Thanks WM8805 I2S signal absolute performance while providing low jitter standard coaxial output
   2. Digital software using bare metal part (so-called single-chip single-threaded), I2S data to ensure no shut-off during playback.
   3. DAC analog hardware using AK4495S, LPF op amp using DIP8 package may be changed according to personal taste, the standard version of LME49720, OPA2134 + BUF634 use the amp architecture.
   The op amp voltage analog hardware are up to 18V (+ 9V, -9V), full high frequency solid state capacitors filtering small pond, amp maximum power (500mW 32 ohms) output ripple control at ± 1%.
   5. adhering to the more simple and more real idea, the whole is the most simple I2S + DAC + LPF + AMP manner, using physical relay protection headphones.
   6. official firmware supports audio formats:

      mp3 (44.1k, 48k, 96k) (16bit)

      flac (44.1k, 48k, 96k) (16bit, 24bit)

      ape (44.1k, 48k) (16bit, 24bit)

      wav (44.1k, 48k, 96k, 192k) (16bit, 24bit)
   7, should support most of the CUE, and purple coral in FLAC spent a lot of time locating algorithm effort, now each audio CUE position is that Quick, Accurate ah.
   8. Supports the third party firmware Rockbox

   9. highly appreciates the mother\'s, says "It seems clear than usual to listen to some."
   and so on ...


   Oh, I forgot to say low-noise, low noise did not get absolutely normal volume, maximum volume + low noise can be heard late at night at low impedance headphones.
   Because the hardware and software is a purple Shan people are doing, it is recommended gray Jun is very important, is the machine direction of improvement, is intended to share music and ideas and the king, to talk to make friends, purple coral can send a complete (to send Alexandra also finished purple dinner it).
   Alexandra did not loom purple sound evaluation, but in addition to sound quality, does not accept the return of all other grounds.
   Li-ion battery itself is dangerous, improper use would endanger the safety of all the consequences of the use of the machine, purple Shan is not responsible for, oh.

   Photographed indicate Jun understand and agree that the above disadvantages and disclaimers.


   Now, this is me.
   how about you?

Fortunately, the player targets close to the theoretical value, not to index Heroes, indicators only tell you that the player no design errors.
