[myfavoritething]

It seems a very good project. I searched something based on ESS, I think I found it. I need AESBU and balanced outputs mostly, but to have extra inputs as this DAC is a nice plus. Therefore, if it is not too late.

[quanghao]

Sorry more questions:
1. when will you have a photo of the final chassis? I am very interested and also wanting to get it with the chassis if it finishes nice.
2. If I have a 95mm diameter toroidal transformer, with it fit inside?
Many Thanks

it is, i can help you now.
Thanks

 

[quanghao]

Is the OFFset output sitting at AVCC with respect to GND (i.e. @ 3.3V)?

yes!

 

[myfavoritething]

Just a silly question, with the opamp output, is there any residual voltage offset on the balanced output (my UCD amplifier has no more input cap) ?

 

[bertchai]

wow.. nice... I am in... at no. 25....

 

[bertchai]

I can change the clock to SAW type later right?

 

[quanghao]

I can change the clock to SAW type later right?

yes, you can do it if the clock

100Mhz wit 4 pin , and run at 3.3V.

thanks

 

[randytsuch]

So I understand it takes work to figure out pricing, you need to go ask for quotes and figure out your costs, etc.

But the current pricing is based on a min order of 20.

Since it now seems likely we will hit at least 30, which is a 50% increase, do you think the price could go down at 30? 40?

It seems that now that the group buy is a go, looking at the past few days, the group buy is gaining momentum.

I think if you could lower the price based on higher quantities, more people would sign up, and everyone wins 😉

Please consider this.

Randy

[smoothquark]

Any further news on the price of chassis ? I do really like the chassis but just a few questions:

1. I would like to incorporate a cubox module (SolidRun - Home of the CuBox) within the chassis to have a music streamer - I am not sure if there is sufficient space (rought 55 x 55 mm required)

2. Is there any chance to customise the backplate (more cutouts for other connectors)

3. Is there a possibility of buying matching chassis for a mini-itx motherboard and amplifiers?

A really silly question - if I get my own chassis (modu), how do I mount the LCD to the front panel, or the boards to the base ?

Thanks.

 

[danny_66]

Hi smoothquark,
About the modu case: you can order the case with a 8mm frontplate, then it is easy to drill some holes and tap threads inside the holes.
Then you can screw the LCD to the front panel.
Regards,
Danny
