Default Preamp question/ input gain boost

The one thing that intrigued me about the SI T-amp are their portability. I had thought for some time about making a portable unit and then I saw the project over at Parts Express using a SI 5066 T-amp, then I was hooked.

Of course, when I first get this amp, I'll hook it into my home stereo just to play with it a bit. I'm sure I won't need a preamp or anything of the like (since not too many porfess a need for them here), but in the portable world, devices like CD players and MP3 players are of considerably lesser output (usually headphone outputs).

Is there a preamp out there that will provide some gain for the input signal going to the amp while running off a 12vdc power supply? (probably a SLA battery)

I have spent at least 3 to 4 hours searching and while some posts do include info about preamps, they seem to be focused on the home stereo relm, not portability.

You still wont need a preamp, I've used one of these things on holiday with some small speakers and you can certainly make some noise! and I ran mine from my mobile phone!

I hope you have a big bucket of minutes!

Anyway, I have no idea what to expect with this thing. All I know is it's getting treated like the second coming

I'm trying not to get too caught up in the hype, only to be let down. I've been down this path with audio cables and well...

I got a couple of DIY fullrange speakers just itching to get hooked up to this little T-amp. I just have to wait on the mail now.
