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.

Thanks Danny. Looks like modushop will customise the front panel. Might be easier than I thought!

OPAM DIRECT OUTPUT NOT go through a capacitor, you can connect directly to the amplifier, WITHOUT PRE, and use the volum of dac

please see the circuit:

and some i was measure of output IV opam whit balance input, see this link, and post 65

Hi quanghao, which is the total cost of a completed dac (DAC base+ I/V op + OP +chassis + transformer + Amanero USB-I2S module ) ?

Since you're selling electronic material do you have any cutomer feedback about custom
that could be applied (since I'm from Italy may be Andrea have some info about that)

you can take a look at this picture to make chassis for easier, cut the hole behind the DAC.

Thank you for your trust, I am planning for a complete DAC.
estimated selling price less than $ 1,200 (only for members on diyaudio), 1 year product warranty.

Hi all!

I had planned production orders dac kits in 1 to 2 weeks, hope you peace of mind.

quanghao,

What will be the cost including shipment to the EU?
Just the basic stuffed/tested PCB.
The 1200-450=750 price-tag for a op-amp IV, transformer and case does not appeal to me

[smoothquark]

I presume the dac board (450) + IV board (60) + opamps and connectors / cables (?) comes to about 700 max. 500 for chassis and transformer does seem excessive ?

Anyway, is there anyone else thinking of getting a chassis from modu ? If so, perhaps we can buy a few units together and bring the cost down? I am considering one of the following:

1. 2U slimline with 10mm front panel (450 x 280 x 80) (1NSL02280B) (Euro 54)
2. 2U Pesante with 10mm front panel (450 x 300 x 80) (1NPS02PB) (Euro 45)
3. Galaxy with 10mm front panel (330 x 280 x 40) (1NGXA348) (Euro 46.50) but likely not high enough

Customising the front and back panels for cut outs costs extra (roughly 75 - 90 euro for both), so, roughly about Euro 150 exc tax. I think feet might be extra as well as any engraving. Perhaps about 180 to 200 Euro in total? Seems quite reasonable... Not had a detailed look yet. I think they have a service to design a case based on drawings and photos.

Hmm.. looks like the chassis may be based on this (preamplifier DAC headphone amp 3207 USD 54-) ? If so, I would be happy to purchase the chassis from quanghao and possibly get another one for my streamer.
