So, I just bought a pair of Grado 225s, and I'm looking for some suitable portable amplification that would also work with other headphones. Now, I considered buying an RSA SR71, but they I figured, why not give it a try, myself? So I'm wondering if you can post pics, or link me to a tutorial with included pics of your own homebuilt amps. Keep in mind, I'm fairly new to this.

Don't waste your time with the cmoy. I recommend that you go directly for the pimeta and mini3, both are top notch DIY portable amps that sounds as good as any of the RSA offerings.

Whoa. Mini3 looks amazing-- Does it stand up to heavy abuse? I'll be using it with my Grado phones and iPod (and later vinyl player) as source, but would it work with something that has a smaller output than an iPod?

I recall another (commercial) amp manufacturer whose amp is housed in the same extruded aluminum Hammond enclosure that Mini³ uses, had a website that shows pictures of a BMW sedan driving over the amp, to show how strong it is...

Although it may be kind of fun to try to repair a smooshed amp.....damage caused by parking a motor vehicle on your amp is not covered under the warranty so please don't try it.

I dropped my mini3 about 9 feet from a ladder to the concrete driveway at my house...it suffered a small ding on one corner, but had no internal damage. The battery was still fully seated in the connectors too.

Mini3 will be a little harder for a first timer with the SMD components. I would recommend the JDS Labs cmoy bass boost as a first one. It's a little more expensive, but the website is great, John is quick with support, and it will go a long way to introducing you to how a lot of these DIY projects are setup. I built mine a couple months ago and I'm now fully entrenched in DIY.... not sure if I'll ever get out!
