The BIG weekend tweak!

Chassis carved out of a single aluminium block


Is aluminium a special alloy, French for aluminum, or a typo?  

for which model do you get this?

Because my understanding is that the D Premier and the D 250 are different from that perspective than the D200 and D120.

if you look at the remote you can also see a difference.

I'm finding the quote about a single aluminium block on the D800 or D250 pages but not on the 400, 200 nor 120.

I know that for the 200 and the 120 they used solutions that are less expensive to manufacture: for instance the shapes do not have the curves of the D-Premier D250, but instead flat surfaces that are easier and less costly to manufacture.

It is very possible also that they went for a material less expensive for the D200 and D120 (brass based alloy with aluminum coating explaining what Manoet analysis is showing) while the D Premier and D250 are a solid bloc of aluminium miled and hand polished....

Just an hypothesis, but that would make a lot of sense to me.

Well I did not look carefully enough... the single aluminum bloc is also quoted on the detailed specs for the 120, the 200 and the 400, so my bad.

The only difference remains hand polished for the D Premier and D250.....

Very easy to get confused.  I think the Devialet website is a mess. I hate using it.

Quote is from this link for the  200.  http://en.devialet.com/expert/#models/ex...ge/le-200/

    I have never been so happy to be so wrong in my entire life! It is indeed aluminum!! My bad. Now I'm again reasonably convinced I can hit my minimum target of 10*C cooler temps especially in the power supply temp sensor. Its a popularly held notion that each 10*C reduction in temps doubles a component's life and I was clinging to that since I've intentionally thrown all hopes of future warranty away. And now with anodizing back in the plan, along my plans for adding passive convection cooling is going to go a long way insuring I see nearer the 12-16*C 'idealistic' reduction I had originally hoped for. And I'm confident convection cooling lowering the power supply temps will also go a long way dropping the digital/analog board temps. A nice cooling Newtonian breeze blowing across things that costs nothing. This is truly win/win for me. YES!!

[Music or sound]

I understand the influence of temperature on component life (especially caps) as I had one of the early Pass Labs amps which was great for a few years but then slowly deteriorated. But some circuits perform optimal at higher than room temperature. My D250 is better sounding if it is playing for at least 20 mins. So how much reduction is optimal?

[Manoet]

Ideally I'd like to see temps in the 27*C range across-the-board. Doesn't mean I can achieve it! I can't achieve it now even in standby overnight. You're absolutely correct that temps can affect SQ positively or negatively... some components like hotter, some prefer cooler. My plan plan is for using an identical count of 6mm holes (maybe 6-12) instead of slots at inlets & outlets. That way I can use small black tapered rubber stoppers on the inlet side hidden underneath at rear of bottom cover to fine tune incoming air varying amounts. Intuitively I believe that will also be more efficient for me with wall mount than same setup as a table mount.

Manoet,

Not that this is that important, but given your experience with Aluminium, I would be interested if you could elaborate on why you were brought to think that it was not (I understood that it was based on density) and therefore since it is, why is it so dense to drive you mislead you. Must me something not that obvious that I'm curious about.

Thanks a lot,

Jean-Marie

Jean-Marie, It's a valid question but I'm unsure if I'm able to answer satisfactorily for you as I can't even for myself. It just felt so heavy to me for it's size & mass when stripped to its core. Still does! Maybe I'm weaker than I believed. Or I'm losing it. As I said in an earlier post if it were to have felt only a percentage heavier or even double I might not have noticed. But to have felt like a component made from a metal over 3X as heavy as it should is puzzling to me. I have no explanation behind that and apparently have no business guesstimating weights or the heft of an object these days. Old age, senility, prattle-mindedness, amnesia? It's crossed my mind.

[NickB]

nick any reason you seem particularly aggressive to manoet?

your speakers are heavy because they have drivers in them, nothing to do with the aluminium.

i get that you dont agree with the way he thinks, but feel free to leave well enough alone. if you antagonise him every chance you get people will begin to look at you in a negative light and be less open to helping you if you actually need it sometime.

Manoet might get to the end of his tweakend (im trademarking that ps its mine) and go oops im an idiot it was actually aluminium all along, but guaranteed he will tell us either way so lets just see what the outcome is.

Not at all aggressive and the weight of my speakers has very little to do with the drivers. They are heavy because they are made of 1/2 inch thick aluminium which is very heavy stuff.

what the hell! are they custom?

So not so far out in my aggressive assertion that it is Aluminium then  

No they are not custom they are Magico S5 made from extruded 1/2 inch thick aluminium and weigh 87 KG each, so I don't move them much !!!

[completeluxury]

nick i never said you were wrong. you just seem a bit grumpy when you respond to manoet!

And at 87kg i can imagine i wouldnt want to move them much either! hope you hit the right speaker positioning early on
