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

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.

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 ![]()

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.
