I did a test with my docking, the sound it not realy more loud but it work well under standard Sansa Firmware. I took a look at Rockbox forum and Rockbox Firmware is not working with the docking without playing in the code.   Thanks for you help,   Max

Curently, it hooked by the headphone jack. I will give a try by the docking tonight. I have to remove Rockbox, it not working tru the docking (it's a beta version).   Thanks,   Max

I know that is an amplifier... it just not playing loud as I want. I do not think this dock will amplified the sound of my Sansa? It will...?   Thanks for all the information on your previous post... This is pretty interesting. That a projet I want to do one day.   Regards, Max  

First, thanks to all of you for your answer.   Ok... it will be my first project of this kind I do not want something to complicated. I heard that tube amp have a more "warm" sound. And it look cool to.   The real thing I would like to do with this amplifier is boost my MP3 player...

Hi, that's my first post. I found this forum by looking around for a headset. I found the DIY section pretty interesting. I would like to build a amplifier for speaker.   I'm newby but I have some skill in electronic. Is there a amplifier you can recommend to me. I found the ''Bijou''...
