it'd be great to organize a single parcel to canada (to avoid multiple shipping costs and import taxes) and then distribute them within

I too am interested in joining in. I have for a long time been thinking about building a simple non-oversampling TDA1543-based DAC, and this seems like an ideal opportunity. Jean-Paul, do you have a guesstimate on when the boards will materialize? Any guess on price? Might it be economically wise to do a group order on chips as well? I guess administration is easier since we're getting the boards as a group as well.

May I put in some suggestions/requests for this Board?

First, provision the use of both receiver and Chip as DIP and SMD encased Item, as supply becomes more problematic.

Second, consider providing for the asyncronous reclocking (SMD Chip 74AC74) using a canned X-Tal Oscillator.

Third, how about allowing for the use of both TDA1543 & TDA1545, including the required different components on the "ref" pin?

Could we have a schematic before commiting?

I would be interested as well if it had a provision for I2s input and possibly supported TDA1541A

Is the CS8412/TDA1543 combo phase inverting? I think I read that somewhere, but I would like it confirmed. If yes, is it possible to get the correct phase in other ways than reversing the speaker leads (eg. reversing pin 9 and 10 on the receiver input)?

No, I don't think that the ICs invert the phase.
But I've read that passive I/V inverts it.

But this has to be confirmed, I'm not 100% sure
