Yes, very interesting! Have ordered one but have to wait - estimated delivery date is late june.
I wonder if that tiny box can replace external USB cards at all or if one still need an external JCAT/PP USB card and the REGEN adds its positive influence up to them!?
Will report when I have it.

Not overly excited
I'm sure it works but
Doubt it will match performance of USB cards and with a few losses in cabling
but on the sales end its got a much larger market cause it will be compatible with all devices with USB phones nucs laptops PC

Saw a coment saying they had discovered some effect by putting a resistor on the usb ground, ssomeone tried 5.5 ohm and said it made a difference

I think you'll be right, but if it betters the sound in combination with a USB card, it would be nice as well.

First batch were 95 devices without resistors. These are already delivered. Starting with the second batch they are delivered with the addtitional resistors.

Sure sounds wrong, though.

I am sure it would make a difference - just what kind?

Seems a clumsy way to give some isolation but there has to be a better way. One can not get around improving the power supplies which would have to be superior.

If adding a resistor improves the sound in nige2000's system I would have to take this more seriously.

Isn't all about noise? If I would have a music system without any unwanted noise and with 100% of the wanted signal, so that would be the moment I would stop developing my system any further.

my comment was specific the resistor in question
resistors are used as a clumsy way of isolating

in this case the noisy gnd from the pc getting into the dac
so its effect will depend on which is the lesser evil the resistor or the pc noise

has this yoke not got isolator chips?

anyway its easy to try a resistor on gnd on the usb
if it works well id be looking to solve the issue rather than a quick botch

Would someone be so kind to Hex edit my device info on the latest and greatest of MQN?

It's been a long time between drinks and now that I'm sporting a Haswell-E I should be able to get this going once again.

My brain runs out of processing power when trying to follow the instructions on page 650 and to be honest I don't even know what the difference is between mqncontrol and mqnloader and what is now required.

My Gigabyte Gaming G1 X99 motherboard cuts the power to the USB DAC UP USB port and this alone has made an incredible difference!

Thanking you all in advance for your amazing efforts.

What is considered to be the best MQN non-Haswell version?

have made another step forward, so think this is the end for SQ, shall get the multi file working and a non haswell version out and yes, it is the best most detailed version I've heard.

In the meantime here is how to build a dac according to xmos

Gordon yes please make it for non Haswell
Thank you
