| [#41] Cubieboard A20 Setup Guide lw 兄, 老實說, 我的 pogoplug, cubox, cubieboard, pi, AMD Geode LX800 都比較過. 音質上不是有大分別. 至少我不能在一聽(沒有AB比)的情況下能聽到有分別. 但用 Jplay dual PC, 行 kernel streaming. Audio PC 用win2012+fine tuning service.係一聽便能聽出有明顯分別. 比上述的好聲好多. 不過, 除左音色輸之外, 上述的有其優勢, 是: 1. 價錢 2. 大少 3. 使用界面 4. 用電/熱量 但如果要攪 compile kernel 又或者太多野, 我諗會失左佢的優勢. |

| [#42] Cubieboard A20 Setup Guide beeos ching, 十分認同在ARM 的架構下Linux mpd, pogoplug, Raspberry Pi 音質上分別不是很大，但在dc 供電上反而有大大的分别。曾經在dc 5v供電 上，比較用Nichicon 10000uf , 同用ROE cap, 同数值，Nichicon 可以感動，而ROE 可以"走"音，朋友幫耳下試音作出的評語，所以注意力放在LPS及電容的表現。 |

| [#44] Cubieboard A20 Setup Guide 玩Hifi講求平衡,mix&match,耳仔收貨，大牌子贵在調音,故用平價中性線材反而好聲. 我不懂電子,但相信電對hifi非常重要,正如部cubieboard加了ifi usb power 後好聲好多,適當改善電源一定有幫助. 其實compile 個kernel只需打幾個commands,比起改電子簡單好多,但可針對自己的要求加减components,分毛不须但對音色改善好大. 以前玩Linn DS,每以update完software都有驚喜,非常佩服. 最後修改時間: 2013-10-16 20:10:34 |

| [#45] Cubieboard A20 Setup Guide 個wifi攪掂，mubox冇裝到wpasupplicant，自己install返就得。 但係個mpd就好多問題，第一我改返bind_to_address做any會start唔到mpd，用localhost先得。第二我播播吓歌突然sa sa聲，嚇鬼死。第三就有時play唔到aif，出 ERROR: Failed to decode xxxxx 之前自己裝嘅mpd 0.16返而冇乜大問題，只係間唔中auto start唔到，要ssh入去人手start 之前諗住攪掂後再整返隻PSU玩，都係放棄 |

| [#54] Cubieboard A20 Setup Guide (update for Cubietruck) bennycp hing, I try to follow your tutorial in #52. For the first step, why are there two links? I guess you try to install Linaro server onto the nano of cubie, so the second link is the Linaro server image. How about the first link? Also, I downloaded PhoenixSuit, installed the drivers, it shows my cubie is a usb device, which means it enters the FEL Mode, but the PhonixSuit still shows not connected. Do you have any idea? Thanks |

| [#55] Cubieboard A20 Setup Guide (update for Cubietruck) Beeos, The first link is for SDCard and second is for nand. You are right that we should use PhoenixSuit to flash the nand image on second link. Nand will have two partitions and we need keep the first partition for boot files and format the second partition to copy the Voyage files. Once you finish to flash the nand image, you can boot the Cubietruck using the Sdcard to setup the Voyage and compile kernel. |

Cubieboard 2 and Cubietruck are similar in the setup except the kernel and boot script. Therefore, you can flash the nand image for cubieboard2 in order to get the correct boot file. |
