I also would like to know more. as i'm going to be installing an HDMI i2s module from Audio-GD
the input module. I plan to feed the soekris from my DIU8 (xmos)that I modded with NDK clocks. and will output via hdmi output to the soekris hdmi input. I hope this is possible? proper wiring? wondering where all the pins would go on the input board, or ? i'll be using two dam1021's
I would love to compare direct i2s HMDI vs my waveIO
plus it's just nice to use my DDC to control all my dacs

I have just downloaded the newest firmware ver. 1.06 to the dam1021, but the uManager says that the FPGA firmware is still rev. 1.05. How could that be?
Isn't 1021full_106.skr supposed to the full monty including uManager, FPGA and filters?
I have even done the whole process at least three times just to make sure I got it all right.

It might not be that clear, but if you read a little more on the download page you would notice that only the uC firmware is updated to 1.06, the fpga stays at 1.05....
I updated the firmware to 1.06 last night. But the sound seems thinner and not that firm. Eventually, I go back to 1.05.

Hi Soren,
If I want to connect AES SPDIF connector to dam1021, should I add a AES to SPDIF circuit before the circuit you mentioned in official doc? Or is there a better way?
I am running dual dam1021 as balance, is the connection for SPDIF the same?

I am using the NMR
will need an extremely clean i2s
what u using?
network interface - Electronic, Engineering and Consulting
Ditched the isolators(thanks nige2000). Using I2s from SDTrans384. So far the biggest subjective improvement to my ears, other than the shunt regs on the shift registers, a bigger improvement than giving the clock its own supply. I hear less 'electronic' sound, more natural timbre.
I'm aware it isn't supposed to have any effect...
The NMR however contains a DSP running at 600MHz, I am not sure will it be good or bad to bypass the isolator, I will do a trial and see.
Hi microzyma,
For the "giving the clock separate power", is it possible to give it a fixed clock to dam if my source is only 44.1? Do you have any idea?
sdtrans should be safe enough bet in comparison to connecting it to the garden variety switch mode power plant pc
so i doubt its a mod that will benefit in all situations
so there is no sure guarantee of improvement
any chance of info on the shunts your using or is that a secret?
doesnt seem straight forward, but i definetly would be quite interested in discussing any fixed clock replacement ideas
id be surprised if anyone has thee answer
however im sure its quite likely that it will be said that subjective testing is inconclusive and any real results would be electronically measured ones
quite bemusing thinking for a way of evaluating subjective devices
I have bypassed the isolators and hear an improvement.
I would not have paid $500.00 for the improvement but since it was free ...
The thing about these measurements is, so far, we can only measure what we can measure and that does not seem to be enough.
One wishes that the "measurers" would spend their time trying to find a way to measure what the listeners are hearing instead of saying what they hear does not exist. Well, it certainly does not exist for them since they never bother trying the things the listeners have found are useful. The listener camp would welcome a measurement that could identify the good sounding component from the bad. But like a cure for cancer this seems to be elusive.
I am speaking of the subtle qualities that separate the average from the really good.
One has to be reminded that all science begins with an observation not a text book. If something is not tried then no one will ever know.
No one tries more things than nige2000 and that would make him - suspiciously similar to a scientist.
