B'ASS Current Amplifier

[manisandher]

For me, at this moment, the most important is the knowledge of how many people still apply because this is so heavily related to the price of the case.

Hi Peter, the price remains OK for me. Definitely one #3 for me for now. (I'll send you a PM with some other thoughts.)

Cheers,
Mani.

ok for me too
maybe I will switch to a number 3, but I guess that a decision on that is not necessary today already

Thank you Leo. Indeed that decision is not necessary right now.

Volume control with B’ASS

Hi Peter,

remembering my „pre amp“ times, the SQ was superior with a
XXH volume setting of -6db.
 
Question:
A) your prefered XXH volume setting is where with the B’ASS? (without VC)
B) did you perform comparisions with a B’ASS “volume control”,  setting XXH “VC” to appr. -6dB and your present XXH setting.

Hey Joachim,

I never used a volume control with the NOS1(a) in my life.
Of course I am going to for this project, soon, but I am not going to attempt serious listening through any volume control anyway. I will measure though (and we will see later that this tells enough).

Peter

Hi Peter,

my experience in other words:

A) playing muisc without a preamp (since 2 years) the XXH VC setting is between -27dB and -36dB depended on the present prefered SPL .

B) Using a pre amp the XXH VC setting was -6dB then, and with that setting the SQ was superior to A) - I remember that Coen wrote about this impression too.

It seems there are SQ differences within XXH with different volume settings.

Hi Joachim,

That is correct. And that one can try to experiment with this, has been brought up by myself. This is because the D/A chips have a sweet spot. Of course it requires a volume control to be able to test this.

I'm still in for the BNC in and out model.

Keep going it all looks really good.

Hi Peter,

Can I join now for a number 2.(RCA and XLR) The price is OK for me. Thanks.

Hi Leung - Yes please !

Thank you and regards,

All of you, thank you very much so far !

We are at 16 now (the original subscribers counted 24 IIRC) so I hope we can find 4 more in order to comply to the price of the case. So please, respond if you wish to have one and do not think "oh well, I will get one anyway, later". So it is really about the batch size and while the price of mentioned "205 euros more" is about a production threshold of 20, in realilty it is about a batch size of 25. Thus, I will let make 5 more anyway which is my own investment (no worries, I am fine with that). Now :

What I will do is apply a sort of sliding average, thinking that I will let produce always 5 in a batch. This will be ~150 per piece more then. However, say that I let produce 5 more for the first batch (now the promised 205 euros more applies) then on average this is actually 150 / 2 = 75 more when we also take into account these 5 I let produce more anyway. This means that when the first batch is sold out, a next costs 75 more (anticipating 5 more subscribers after the first batch sold out).
If I can sustain the batches of 10 to produce with an actual order quantity of 5, it shouldn't be too bad if all new ones after the first batch sold out, are 75 more.

Long story short (and sorry about the brainstorming character of this post) : There will be a first batch of 25 (or more) and it can be produced against the promised price(s) as mentioned in my earlier post (this means that the 205 euros more than the original wooden box, can hold). This batch will be produced when 20 subscribers are there (16 at this moment). At some stage we'll pull the trigger and after that every new subscriber pays 75 more (and new batches will be produced when 5 orders exist for this new batch, while a produced batch will always consist of 10).

Thank you all !

Hi Peter
  I'm also in for a modified #3 with VC and extra RCA/BNC inputs if still possible.

[esimms86]

I'm still in Peter but I've decided on #2 instead of #1. Thanks again.

Thank you guys. We're at 19 now, so I suppose the 20th will be there soon.

But prior to that we are trying to make something of that finish;

I can tell you, the pure aluminium (aluminum for some) looks really cool. It also looks like such a thing is not being done. It looks too good to be true.
Well, possibly that is right.

So far, after many many hours of research and also trying some things for real, it looks like it is impossible to apply some clear varnish etc., because the first thing to deal with is the "veil" of fat that actually springs from the aluminium itself; when you deal with this, you can feel that you squeeze out the inside fat and next wipe it over the surface.

This material is realy strange, because when you wipe it with water and make it all dry, all the gloss vanishes, although the surface remaining from that is quite "equal".  You could like it, not knowing what's under the surface (for super gloss).
Don't like it ? then it takes 15 minutes to get rid of that glare.

Point is : At this moment I am unable to create a "stain-less" surface, so the possible varnish over that will only seal the stains. So now I am going to an anodising company and ask what possibilities are.
And no, that was not contained in the price (grr).
