This Instructable will show you how to use a laser cutter to etch anodized aluminum. I live near a DIY workshop called TechShop - they have $1M worth of equipment that I can get access to for about $100 a month. One piece of equipment they have is the Epilog laser cutter. Etching aluminum with simple text or customized artwork is virtually as simple as printing on an inkjet printer.

I start here with the blank, black, anodized aluminum faceplate for my DIY home power amplifier.

That's a really nice one techshopdude!
Could you throw some (or a lot of!) light on your amplifier design and construction?
I love DIY audio, because I've been able to make some equipment that puts to shame some store bought onesmany times as expensive... :)
I'm in the process of multi-amplifying my setup, using 24dB/Oct electronic active Crossovers, in order to have a lot of flexibility when trying several different drivers, since one could easily match sensitivities and crossover frequencies/slopes etc.

I used the the classic 3 stage class AB amplifier design you see in books like Douglas Self's "Audio Power Amplifier Design Handbook".
The heat sinks are from Conrad Heat Sinks in Australia. The case was from a supplier in the US named Par-Metal. Switch from Lamptron. Back connectors bought on ebay. Toroidal transformer from Plitron in Canada.
Too much to describe to make an Instructable though maybe I'll try it piece by piece.
