Need to boost output of MP3 player....

[JoeDJ]

I got that FiiO E6 today. It really does not increase the volume that much..... hardly at all actually.

However, the E6 does seems quite usefull when using my MP3 player plugged into the AUX port of my car's less that stellar stock stereo. So, I will still have a use for it as I suspected.

I wonder, would an average 9v a CMoy amp have a higher output for use in my home sys?

A full size CD player can output 2vrms. Thats around 5.5 volts pk/pk and so an opamp (or transistor) gain stage running from a single 9 volt supply should be plenty.

Does the Clip+ have the volume limiting "feature" activated? Supposedly, there's EU firmware that makes limiting mandatory. Google Sansa Clip+ volume limit

Thanks for the input...

The Sansa Clip has plenty of volume (purchased in the US) with both headpones I currently have.....a cheap Koss used stictly for computers/outdoors and my much better Audia Technica phones for music. In fact with the Audio Technica phones, I can turn the volume down to about 2/3.

As I said, the voulume only became somewhat of a problem when fed through my home sys when I got the less efficient AS speakers and only with some songs.
This is why I want to get some sort of inexpensive "preamp" to boost the output a bit. Also, running the Sansa at full volume depletes the battery faster.

If no one has a better/different suggestion, after the new year, I wil try one of those inexpensive 9v CMoys amps on e-Bay..... the ones from the US dealer that use the TI opamp 2227 chip.

He seems to use high quality components.

For me, it's not worth building my own as the price is relatively cheap for an assembled one.

FWIW. .....I got a CMoy amp and it solved my problem.........volume is now more than adequate for the most part.

Thanks for the update.
