I will try to build high end like 200W monoblocks and this is my progress thread. Please object and advice, I shall be very grateful.

Enclosure made of thick aluminium, 3 feet for easy adjustment and stability.

Pair of single ended inputs from Neutrik panel mount and High quality Speaker binding posts (pair for bi-wiring although I don’t believe in this ********).

Airflow from bottom.

Aluminium enclosure:

From Czech manufacturer CustomWorks
I have to say, this company (coming from EU) surprised me by their speed, communication and quality of manufacturing. PCB is very thick, almost unbendable, amazing soldering and parts quality. HIGHLY RECOMMENDED!

SOFTSTART black

Eloxed aluminium feet 60mm – They actually look much better in real.

In the end it should look something like this:

4.
Custom made aluminium isolation feet 6pcs (2x 3 for each monoblock)
from Custom Works.cz.
Such a shame, my pictures don’t give them enough satisfaction. In real they look miles better.

5.
Alu enclosures. Sorry for shitty pictures, hope it show up how amazing they look.
Real beauty! It’s a bit messy from unpacking, but be sure the finish is high quality.

I’m still waiting for modules from Anthony Holton, he was ultra fast with his couple-of-days delivery,
but custom clearance takes sooooooooo long. Stay tuned, updates are coming soon.
 
Enclosures should be RE2417WH from SiliconRay. Didn't have a chance to see these but we did a powerbuy for some different ones and, indeed, quality was amazing regardless of (the affordable) price.
Airlink make some nice mains "balanced" transformers. 😉

I have to conform your claims about siliconray.com, service is great indeed! Enclosure looks much better in real. High end quality of finish. Also very friendly communication.
 
Heatsinks Conrad 35-70, speaker protection modules and Amp modules from Anthony Holton. All very high quality, simply stunning!

I have finished design of inside construction for amplifier. It should look clean and tidy. CNC milling is from QuickPanel They using their own software which you can download for free. Very simple and pretty powerful program to work with. You can check a price of you design by automatic online calculation. I love it!

This is my progress so far. I have put it together to see where should I make threads for PCB's.
Getting there

Still was waiting for bits and pieces.
