^^ Agree, I picked up some pretty nice aluminum enclosures for $5, will post that later once the individual amp channels are finished.

Little Update:

I got the power supply completed and working,

I'll have to start on drilling holes and mounting the power supply into the enclosure and start on the amp channels this weekend. More pics to come!

^Sure is, I got one channel to work today, sounds really good. I threw the right channel together just for testing purposes with the minimum amount of components. Moving onto adding all the coupling capacitors along with filters and getting everything ready to go into an enclosure.

For now I got a few pics of the point to point test build on the right channel.

New Update...

Haven't had much time to work on the amp lately, but there's a lot of progress since last post. I was able to build and test one channel, play around with some numbers and components to get the best possible sound so here are the pics of how it currently sits...

Aluminum Case purchased for $5, a little scratched but will do. Will polish later.

Right channel in build progress

I'm waiting on the RCA chassis mount jacks and volume control pots with knobs, once those arrive and the right channel is completed, it should be finally finished.

As far as the sound goes, it's absolutely amazing. Extremely clear and detailed highs along with tight mids and some decent bass. Can't wait to build a better pair of bookshelfs to eventually replace the Polks.

Nice progress, curious to see what you do with the AL enclosure. Its going to be a very nice amp thats for sure.

I'll be happy to make some speaker recommendations when you get to that point

Another Update:

Amp completed for the most part. Been running for 3 days now and I'm absolutely addicted to the sound.

The station:

I'm going to run it for another 2 or 3 days, then pull it out, shrink tube and organize the rest of the wiring, polish the enclosure and install the lid. I'll be also wrapping part of the enclosure in carbon fiber vinyl.

Currently I'm running Polk 30s and Polk self powered 12" sub. Planning on building some speakers here soon, gotta let the wallet recoup first though
