Hi-end DSP based multi-channel integrated Preamp/Crossover/DAC project

Nice to see some progress!

8 channels aes/ebu input (4 xlr) is on my wishlist.
HDMI input would be the dream.

Can you give us some approximate price?

Now that the ESS9018 is no longer in production, are you thinking of swapping to 9028?

8 channels DAC, 32 bit volume control, OSF and jitter eliminator

cheers

Are you using a single clock?

or ES9038 PRO ? I assume there is one which is going to be a drop in replacement for the ES9018S.

Would HDMI be used just as a Video pass through (like NAD MDC module) so the sync of video and audio is better or you need it for something else?
BTW I really like the way M22 from NAD looks like. Hopefully the looks of this DSP could go that direction.

IMO ESS has a couple neat tricks for convenience, but not really for ultimate performance. The time domain jitter thingy? I don't think jitter can be eliminated. So probably two clocks are better than one.

HDMI transmits uncompressed audio, unlike SPDIF, so it's very attractive as a means to get audio from a great blu-ray player (think Oppo) or media PC/Mac into this unit. It's essentially a way to get I2S audio signals between units. I would also love to get HDMI input, but it's not inexpensive to pay the licensing fee.

It's more like jitter reduction than elimination. I don't see how two clocks reduces jitter anymore than having one low jitter clock. The DSP only runs at the one sampling rate and the digital filters are calculated accordingly so there is no need to have more than one clock.

Haven't studied the datasheets, but Ess claims 9028pro to be pin compatible with 9018S.
