But what did you mean by this previously?

p.s. Sorry for bothering you but I need to know the situation before buying.

I thought you were referring to 8 channel input.

cheers

Well, again - no way to get 8 channel output of I2S (4xi2s) after your DSP, right?

Not easily and not without losing some functionality that comes with the on-board DAC. This project is more concerned with improvements that come with proper crossover design and/or room correction than it is with fiddling around the edges with different DAC architectures or vendors. Had we made the mistake of changing DAC vendors as has been previously requested of us then you wouldn't be seeing this upgraded version today and the DSP capability would have been hamstrung just because someone thought that DAC vendor A's chip had more 'fairy dust' and a wider 'sound stage' than the DAC vendor we are using

cheers

Please do not think wrong, I am very well aware of the meaning of your complete solution in terms of relevance or rationality. The question is not this, but that in some cases it is more profitable to transport the digital stream instead of the analog one. So, if you do not mind, could you briefly say what specific functionality will be lost if to use I2S before the ES90х8? So far, I see the lost of one function only - volume control. What else?..

p.s. Thank you David, I believe your answers will help others to understand your product a little clear/better.

@David:

Do you have a rough idea when this bad boy's coming out? If it's next week I'll hold off on getting parts, otherwise I'll put together a mid-high passive xover in the interim. Either way my rack has a space marked DSP so the time frame isn't all that critical; the delivery date mainly affects whether or not I buy a pile of coils & caps for testing purposes. Thanks!

Getting closer to the mark but even if I could offer a pre-order today it will take a while to get the number of orders needed and then the delivery will be quite a few weeks after that so you may have to make do for the time being.

Currently working on the updated Digital Audio Interface (DAI) board. Here are some 3D models of the final version FYI.

cheers

No worries, all good in the hood. I'll have fun banging out a couple more passives & getting my FIRs in a row for later.

By the way, for those of us not completely enamored with SPDIF guessing at sample clocks, will there be an I2S option?
