Thanks for the update.. Can not wait to "listen" to them. Man. would really want to come over to "test" the board! ^^
But from Hamburg its a "long" way!

Also waiting for the new WaveIO Board. My SymAsym Amp and my Speakers are almost finished.

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

I removed myself, since i will wait for a BAL version - and ain't in hurry for this.

Phil,
When the single ended version is available can it be purchased and later the balanced version board be added to it?

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

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
