Sweet! Never thought of using a jewelry box type of thing as an amp cabinet. Was assembly pretty straightforward?

It was. The only hard part was getting everything assembled in a relatively small space... Not much room to work.

Very cool, Steve! I like your creative use of the box. It does look very nice.

Thanks guys! I hooked up the M80s as a final test. I ran the amp at full blast (I-phone was the pre-amp and source)for 2 hours. No tripping, 100db peak output at 1m (both speakers were running), and when I shot the heatsink with the infrared gun, it measured 94F. Not a bad little amp!

One thing I have noticed over the last week or so of listening is that the I-Phone just does not have enough "umph" to serve as an adeqaute pre-amp. When I hooked my Onkyo receiver up to the amp and used the pre-outs, I was really able to push the amp and the sound was great. So, I decided to hunt around for a little pre-amp (or headphone amp) for the amp I built. I finally decided on this one: http://www.ebay.com/itm/Indeed-G3-Headph...=item3a699d3c70It's a tube pre-amp/headphone amp, and it looks like a tweaker's wet dream. Some guys on another board had a chance to play with it and some have even modded it a bit: http://rockgrotto.proboards.com/index.cgi?board=b&action=display&thread=7174#It's on it's way from Hong Kong right now, but it won't be here for a couple of weeks. Has anyone here had any experience with this unit? I know some of you are into headphone amps.

That's gotta be good when it's described as "it sounds with rich bass and clear treble for joy"!
