Paid my $225 for one dac base

Costs

Hi, could someone please tell me the prices for each part of this group buy?

I saw some posts mentioning 450USD for the DAC base, and now I see payments being done, for 225USD?!

Thanks for some help.

Hi Quanghao and Andrea

Do you plan a multi-Channel version in the future to follow digital filters ?

BR

smoothquark · 2013-03-17 1:13 pm

Some more questions:

1. Volume control via USB

the amanero combo384 can act as a i2c "master". Is there any way to have a two-way communication with the dac-end microcontroller, ie send volume control commands via USB to the combo384 and then on to the microcontroller to raise or lower the volume? If so, it would be fantastic!

2. standby option

Is it possible to add a standby circuit?

3. Remote in/out option

Is it possible to have remote in/out using the microcontroller, ie to control other hifi equipment?

4. 12V trigger option

Is it possible to have a 12V trigger circuit controlled by the microcontroller?

5. Chassis

I am now thinking of housing my mini-itx board in a matching chassis. Quanghao - are you able to get the company making the chassis to make a different front panel with just a switch and ideally a LED indicator ? I am also thinking of building a pair of hypex ncore amps in a matching chassis as well
