Please, can you post more info, and with what speakers?

So! cabinet is pretty much done. I need to make another shelf and a drawer. The top rack unit has pull out lights! Both of the Crown amps are modified by me (bigger filter caps, different op amp, signal capacitor swaps, etc.)
Now I need some speakers to go with this...

Gents,
Sakis is a dentist, a pyromaniac, a peeping tom, and a junkie.
Thanks Jacco - I needed that laugh today...
wood work looks perfect .... though your amps are a concern ...way too old. I hope you been working on them .
Well, they may be old designs but they are the same as the new ones from Crown. I changed the opamps and several other things.
Oh, and thanks but the wood work is not perfect. Of course, I see all the flaws...

I'm making progress on my chip amp. I got to use my new drill press for the first time. I can finally make nice holes in sheet metal now. I installed 2 rivet nuts in M6 size for the transformers. It just so happened that they bolts they provided are also M6. I didn't plan that! wow. Anyway, I'm using the rivet nuts "backwards" so nothing pokes out of the box. There's a Twisted Pear USB receiver DAC in the center, with the Audio Sector LM3875 amps.
