Great work here in this thread as usual. You are a real inspiration, especially Ferrari.

Once again Ferrari, another fabulous looking build! I’m sure it sounds as amazing as it looks 
Question for you, it’s obvious that you put tremendous amount of detail and attention to your casework. I'm not familiar and have never worked with aluminum cases before, I've always wondered what sort of tools and machineries do you use/own to get your cases so professional-looking?

Bah, posting after Ferrari is bad timing, but this project needs to go up now or it never will.
My L'espressivo, based off of Doug Savitsky's design.

Hey all, I just finished my first CMoy, and I'm thrilled that bit works pretty fine.
I'm starting to understand the schematics so I really learnt alot. so now is the time to do some experimenting.
I was thinking of increasing the caps values (220µF power caps, and 100µF sound caps). And I liked to improve them and see what it gives to the bass. Now I only have some 220µF and 100µF spares left, so I was thinking of putting those 220µF I got left, which worked as the power electrolytic caps in the first cmoy. So I was wondering would the electrolytic caps do good, or not (because they're electrolytic and I heard they would cause distortion).
Also i was looking around about putting caps in series, and when neglecting the resistance, they also even reduce the caps value. so that wasn't an option. Is there any way I can increase the value of the 220µF caps I use for power, and this with only using the 220µFcaps I have left?
I know if these sound very dumb questions, though it's just a while since I started with this new hobby.

Now idea what takes of time, tools and skills to etch a board like that, but it certainly looks impressive.

Thanks all for the complements. Waiting for enclosure supplies. Another teaser:

ZK, thanks for the nice comment. I have spent some hours listening via my HD650 and this amp really can sing. 
For the casework, I don’t have many tools as some of you guys here have. I have a drill press and it stops more or less there.
I wish that I had a small workshop (like you have) to play with.
The casework starts with selecting my favorite enclosures from HiFi-2000 or ATI (ATI is unfortunately out of business).
I prefer metal enclosure to other materials due to the better RFI shielding.
For all of my build, I spend lots of time in the logical placement of the PCB and wiring with consideration towards EMI/cross-talk, then designing the panels.
The placement of the internals is for the lion share responsible for how the front and back panels look like.
Depending on the available free time, I do the panels myself using drill press ( β22, Kumisa III and my SOHA II prototype)
or send the FPE file to Schaeffer to let the panels done by them (what I did with my more recent SOHA II).
