Well my Sansa clip+ arrived today and I must say I'm mighty impressed.
I picked up a refurb from a UK seller on ebay. it arrived in as new condition not a scratch. along with the headphones and a short usb cable. I took it straight out of the plastic slip and began imprinting grubby finger prints all over it which easily mark the shinny casing. $27.99 AUS I paid. I chucked rockbox on straight away after some minor hassle finding the firmware .bin file which rockbox needed (more on that later) and placed a 16GB SDHC card in. After transfering 5GB of killer Dubstep and Trance I plugged in my SoundMAGIC E10 and was just WOW'd straight off the original firmware HO. This thing is fantastic, what a change from my ipod nano and mini, even my Ipod touch cannot compete with the Equalizer app.
I then paired it with my E11 using the stock 3.5mm headphone cable provided set the volume to 0db and OMG I was amazed, what a little perla of a DAP this is. After adjusting the EQ on rockbox to my tastes I can safely say this was one of the best purchases I have ever made so far, a whole new experience.
For those having problems installing rockbox. Here's some tips. (I did automatic install)
1) Make sure the Clip is in MSC mode.
Settings > System Settings > USB Mode to MSC
Once you auto detect the device using rockbox installer a prompt will come asking for original firmware .bin file. I checked the firmware I was running then proceeded to Sansa forums finding my firmware version. Download that file, click ok when asked for the file and select it where you have it saved. After selecting the file the install should begin. I gather if you're having problems finding your firmware you can just update your original clip+ firmware to the current update first.
Here's the current update and download along with the updater program.
Sansa Clip+ Firmware Update 01.02.16 - SanDisk Forums, Welcome!
