Exactly my thought

"PSU" board is just regulators, in fact, just improved ones - a regulator, a transistor, somes resistors and caps.

You'll have to provideat least +1.2 and +3.3 power rails - say hello to Russ's power supplies . If separate regulators are not enough for you, well, you can buy 3 "2 voltages" power supplies.
Hi,

I sent an e-mail to you, although I will be leaving by the end of the week I have a friend that is going to closely watch the threard for your boards, I hope to get one from the Buffalos too.

Your website seems to say that there are pads for adding filtering. Is this right?

The corner frequency is easy enough to adjust, but I found the Fc I am using now to be very effective. Also, it keep the phase shift minimal.

This is not a value I arrived at to emulate commercial gear. It is what I found to sound great.

Cheers!

in the case of 8ch, any chance to control every singol channel volume?
Thanks

Yes! Just look at the datasheet.

Not everyone has the datasheet
If peufeu wouldn't have sent it to me I would never had it...

I called ESS who said they were sending it to the next day - guess what, I called many times, but never received it.

So yes, you can control each channel.
Please note it's digital control - you'll have to use i2c.

You should know this is a datasheet that ESS only wants distributed with a signed NDA (non-disclosure agreement). Whether or not you agree with that policy, by posting links to the datasheet without permission, you are more likely to 'turn off the tap' of information being provided here by ESS insiders.
