I wonder how well ES9018 perform sine wave... Anyone?
Anyone try to buy the Chord Mojo case from dignisdesign.com? It's a terrible website that seems to forget whether I signed in or not. Also, with shipping, the cheapest case is about $92 for the USA.
Is there another place to get it? I don't mind the cost but the website doesn't make me feel confident about their technical skills or privacy protections. If there is no other place to get it, I might just wait for the official case.
Keeping in mind that it's not just the DAC chip performance, but the implementation that matters as well, and the measuring tools that need to be taken in to account.
Here's HomeTheaterHiFi's measurement of the Benchmark DAC2 (undithered) with the Sabre ESS9018 DAC chip:

Edit: To be honest, after filtering, the sine wave looks very different than the undithered one posted in that article. It's kind of moot to compare different charts and graphs from different systems.
Then comparing undithered wave is only beneficial to 'see' the performance of chips (not actual devices), am I right?
Just to complete the story, I ordered two Mojo cases from Dignis on the 22nd. They were delivered today, the 26th. No additional fees, taxes or duty. Paid with PayPal and shipping for two was the same as for one.
Customs can take up to a week in my experience. No issues with ordering from Dignis.

Average temperatures per month where I live for the last 10 years. Peaks go to 122 Fahrenheit on rare occasions during the summer.
The mojo gets hot, so does the hifiman 901.
Cheers!
I wouldn't normally do this, but, for the sake of Mojo-owners...
I noticed this just listed: www.head-fi.org/t/806272/astell-kern-ak100-mk2
I live in Adelaide, where you get to 44C in the summer. Used the Mojo in 41C ambient for hours and while it got pretty hot, it didn't miss a beat Oppo PM-3 did well in that heat, too.
I read somewhere here that only using a mobile phone as a source connected to mojo via usb is prone to hissing/radio interference which can be reduced using ferrite cores.
If using DAP as a source connected via co-axial or optical, adding ferrite cores will not improve the situation.
So if I used a DAP as a transport than I would not get anymore hissing?
Try a Dynamic Driver iem.I'm not sure about that. The SE846 are very sensitive and they simply hiss with a lot of gear. Not everyone is sensitive to hiss, but if you are then you'll likely hear it no matter what the source is using the SE846. RF noise is very different from IEM hiss.
I hear a slight hiss with the JH Angie and Noble K10 using the Mojo and they are less sensitive than the SE846, and all I use are DAPs with an optical connection to the Mojo (no RF noise with optical).
Try a Dynamic Driver iem.
