AMP to run Fusion 8's on computer

I want to use a pair of Fusion 8's on my computer. I need an amp to do so. What do you think of the following? Is there something else you would recommend?

Unless the bluetooth or better/prettier case are important to you, I'd save the $75 and go with the lp-2020 (http://www.parts-express.com/lepai-l...upply--310-300). It's basically the "industry standard" mini amp. Sure you'll only get about 8 clean watts into an 8 ohm load, but when powering 90+ db efficiency speakers in a nearfield situation, that's about 7.9 watts more than you need.

I use the little Dayton brand model that puts out 15 watts x2 and can run off batteries and it is more than enough power for near field listening. I love this little amp I can take it with me when I go to buy speakers second hand and can see if the speakers are working correctly or not no matter where I am.

That's just what I would've suggested as well. I hooked up my Tempest speakers to the LP-2020A+ to test and they were incredibly loud, even in the next room, and had a lot more room to get louder. Near field should be no problem for any of the SEOS designs.

I got the amp in today. At normal listening levels it sounds great. However, I was disappointed when I tried to crank it. Once the AMP is turned up past 2 o'clock, it starts clipping. This causes some serious speaker distortion.

That said, for $20 shipped I cannot complain.

I keep mine at 12 o'clock and it gets plenty loud--my speakers (Classix II) aren't high efficiency. But it does distort if I turn it up too high.

If you're looking to wring every last but of performance out of it, see if you can upgrade the power supply (2A -> 5A). http://techtalk.parts-express.com/sh...e-Lepai-T2020A

Though, if it's loud enough for you then I wouldn't bother.

You're trying to crank it listening to it near field?

I may try the power supply just to play around. But I don't need it. Originally they weren't near field. However, I brought them in a bit closer and it's much better.

I took some readings and it looks like they max out at about 88dB. The meter bit 90 very briefly. This will be more than plenty. It's when I want the sound to fill the room that I want more.

The main issue is that I know what they can sound like. When played on my AVR they sound awesome and get very loud.
