Hi all,

this is my first post but I read the forum for a long time

I've just added my name in the spreadsheet, I'm scared of soldering the ES9023 but I'm very exciting too

Hi Bill and All

I think so but can't confirm it to be absolutely "true" right now.
BAL version design isn't finalized yet.
In previous V2.6, SE DAC could be upgraded to BAL version.
A second DAC/PCB is added, specially populated to achieve BAL goal.
Hope this help

Regards

Phil

Default Attenuator on output

I think it has been said in the thread that this DAC can be used with its outputs direct into a power amp, with one of the advantages of this DAC being the built in driver stage.

I would like to install one into a power amp with a stepped attenuator between DAC output and power amp input - to control the analogue volume without the need for a pre/buffer. Could anyone clarify if this would be a suitable set-up? and if so, is there a particular impedance for an attenuator that would suit the DAC output best? Thanks. (In my situation amp input impedance is 33kohm).

Is the forthcoming BAL version has 2x es9023 on 1 board or we have to use 2 separate boards?

We are still waiting for the SE test PCBs which take a lot of time to produce apparently. The BAL version is being designed by Subbu. So I don't know what it will be although I have an idea. Maybe if I offer my help I can take a peek ...

thanks for the update JP! maybe you guys should consider subbu dac v4 as a kickstarter project. A little extra funding to help you guys test diff configurations. And anything left over could be used for v5
