@Richard: Looks very cool!

Some random ideas/q's:

looks/affordability:
- what price range are you thinking?
- what finish are you thinking?
- If that box is in total 6cm high, the logo would be near 3cm tall. I'd personally prefer a smaller logo somewhere left bottom or, or horizontally/vertically centered, but that;s just me.

internals: if you're going to do this, lets go all out and be completely anal about details (of course, keeping cost in mind, not too many drill bit changes etc):
- Depending on required "flexibility" of the case (see Julf's question above), what about creating 4 compartments, one for each module (ie. each smps and ncore separated by an aluminium "wall" with a small part left out for cables from smps to ncore). Would it be useful at all? (RF shielding?)
- what about routing out sections for power supply cable to the smps through the middle?
- If I am not mistaken, the modules need to be fixed to the enclusore by 3 screws, which are not accessible from the PCB side. How will you mount the module to the enclosure? To the lid(underside?) or top (enclosure itself)?
- Is tapping holes a possibility (XLR, mounting plates etc), cost wise? Or do we need to use tiny philips-like screws?

- what about smps cooling?
- how do we run cables not over and under SMPS ?

Would be better if the SMPS can be separated from the amp modules like Linn Klimax

I'd like to achieve a price point of 250-300 ex.vat, aiming for 50 pieces.

As I mentioned before, bead blasted, special etching process and colour anodizing. Gives a very chique and smooth finish similar to Apple products. I have a preference for black. Small Hexateq Logo will be lasered, nCore logo CNC cut.

As it stands now, the circle around the first N is just over 25mm.

As mentioned I haven't drawn all studs and notches etc. for fixing all the stuff.

This is absolutely something to be considered, and was on my list of things to implement. I need to draw in the nCore module first. There isn't an awful lot of space left though between the module and SMPS.

I've actually done this. However, the inlet and outlet on the SMPS are at the same side and at the narrow end. The connector is also at 90 degrees hence the module is pointed towards the nCore module.

I'll mount the module to the enclosure, probably upside down like the SMPS. Plenty of height available, no worries here.

All screws will be tapped and included. This is NOT a DIY case.

Rgds,

Hi Arthur,

Nice picture. You're right, separating the modules is on my list of stuff to do.

Cheers,

Richard

Richard,

How about making the enclosure a bit higher, so that the SMPS fits upright?

Got me there. Forgot the inlet/outlet were on the same side.

Not really a DIY amp then, more like plug-n-play

More alu = more expensive. And I like low profile!

As you can see, work is a little slow todya. Me out, gotta get some stuff done.

The SMPS on it's side is 85mm. Add material on top and below and you're looking at an overall height of 95mm. Not particularly sleek and slender.

Moreover, I've still managed to keep the overall profile smallish at 300x300mm with acceptable height.

I suppose I could do an upright cylinder style enclosure which will undoubtedly appeal to some people but probably not sufficient people to make the numbers work.

Cheers,

Richard

I don't expect cooling to be a major issue. I will look at it though in more detail to ensure it all works within acceptable limits.

Cables do not need to go over/under the SMPS.

I have managed to mount my ncore 400 in the (oversized) enclosure of my defunct F5 clone.
I'm not really good at making reviews, however, here are my initial impressions :
- the sound delivered is very refined and appears very natural
- the amp is really transparent and makes me feel that there isn't any amp at all in the system
- plenty of bass which didn't shine with my F5 clone
- very fast - tight control of my loudspeakers
Most important, this amp gives me great pleasure to listen to recordings (my former favorite was the F5 and I had UCD 180, Tact, Linn, Jadis, Brinkmann amps).
