This is for amplifiers that change volume by switching - which the sonic impact does. If it were ten times more powerful, presumably it would only be as good as an amp which switched at a tenth of frequency. However if volume control alters the voltage of the switching power supply then it would work well below tmaximum powerat any power, wouldn't it.

The TEAC A-L700P ($100) is a similar product for those that want more power. Sleepkyng considered it and the panasonic receivers (if I remember) a step up from the sonic impact.

There is a guy in Hong Kong who sells ASL adapters relatively cheaply. PM me if you want his e-mail.

If this really the case, I would have a hard time understanding why there are still non-class T solid state amplifiers out there on the market. Hard to imagine how much better it can get, except for a more powerful output.

I'd like to get one of these to take with me to BBQ's etc...

Does anyone know of anywhere (apart from Amazon.com as they aren't so cheap) that will deliver to the UK or Europe? The places selling at $19.99 that I've found via google will only sell to US and Canada

Also, here are the specs for my speakers... Do you think this amp will power them?

These numbers are quite similar to my own speakers and typical of modern minimonitor design. If your room is not too large, SI will be powerful enough for you.

Oh, that's good to know...

They are currently being powered by a Cambridge Audio Pre-Amp and a Samson Servo 170 Power Amp (85wpc iirc). I thought it would be nice to be able to take the speakers and my iPod over to friend's houses or outside when it's BBQ weather, and taking my pre and power amps is a royal pain!

This is what my T-amp will look like soon:

Thanks to Art Taylor's mods.

Keep us posted.
BTW, where do you get the potentiometer?

TNT audio published a review that is singing praises to T-amp.
It mentioned that T-amp easily outperformed a Sonus Faber $900 integrated amplifier.
It is not suprising my $350 integrated amp gets beaten pretty easily as well.
This is the most amazing thing I have seen in audio, ever.

I'd recommend that anyone planning on using a T-amp for high impedance headphones be aware of the extremely high levels of ultrasonic garbage that will be presented to your headphones. Please see the thread Sonic Impact Tripath amp-->AkG K1000? where we've been trying to tease out the issues.

Does anybody know where to get this sonic impact amp for cheap? I froogled and I've found it for 20 bucks but they're all from seemingly shady-looking stores. I know ecost has it for around 20, but they haven't had them in stock for a while.

Thanks.

partexpress.com ($30) is not shady. I've never dealt with pcmall.com ($20), but I know they've been around for years.

Nobody has them in stock at the moment. I asked Sonic Impact about this. They said they expect to have them back in stock at their retailers in two weeks.
