[QUOTE="Wolla, post: 731995, member: 664"] Hi Skylark, yes I am still using the PAM8406 as per my original post. I have however also tested the TPA3116D2 (on page 2), which works fine as well. Here is my "thought board"[IMG]http://a68.tinypic.com/3484j6o.jpg[/IMG] My main idea behind the boxes are to make them future proof, so one can try other chip-amps, power options and sources as well. It also needs to sound like true hifi in the end, otherwise not worth the effort. So far I'm very happy with the sound. The bottom will be a removable section, and this will contain the fixed (but upgradable), like the actual amp and the 4 5-way speaker binding posts. This section will attach with 4 screws and will be easy to service or upgrade. Something like this: [IMG]http://a63.tinypic.com/2h5llc7.jpg[/IMG][IMG]http://a68.tinypic.com/2gt46k5.jpg[/IMG][IMG]http://a64.tinypic.com/22xmbt.jpg[/IMG] [/QUOTE]
