So the verdict is that it is indeed less noisy? Not that anyone will notice the difference I think 🙂
Amplitude noise sidebands around the signal will be a bit smaller and if there is a substantial DC current flowing through those resistors, the 1/f part of the noise floor will be a bit lower. What matters is whether it sells.
What levels do you speak of?!
Maybe they had many 1k8 resistors in stock. Sometimes things are quite banal.

Here is a resistor current noise graph from LIGO (https://dcc.ligo.org/public/0002/T0900200/001/current_noise.pdf):
Current noise of low noise thin film resistors is only slightly above thermal noise with noise corner well below 100Hz. I would assume other factors in DACs produce more 1/f noise than these resistors.

I like to terminate my DAC at outputs with 50 ohms carbon and sometimes worse AB carbon comp ! I do like their distorsion and noise. Subjectivly sounding more neutral than a RN55 metal I quitely hate (not the RN60).
Elswhere I use Vishay or Yageo, smd same, with sometimes Panasonic. Sussumu RG have amazing specs too.

They say the schematic comes from their evaluation board. Could be they just used parallel resistors in case anyone wanted to easily try changing the gain. Maybe they didn't even know when they designed the evaluation board what resistors they would end up using. Wouldn't be the first evaluation board with something like that.
Good idea, but no 🙁Could be they just used parallel resistors in case anyone wanted to easily try changing the gain
3k6 in this schematics (1st topic post) but seems it may be really quite banal.Maybe they had many 1k8 resistors in stock. Sometimes things are quite banal.

Once noticed a designer always using 68 nF for decoupling IC’s. When asked the reply was that it was not relevant and just a habit. “Someone has to use that value”.
That is ES9280A which also has a DAC. Not much information available without contacting ESS.
Maybe the ESS company does a good job drawing attention. And/or they offer good conditions/prices to the industry. The popularity till ES9039 was not exactly built on quality sound but everybody in audio spoke about their ICs. Here many projects were done with the same ICs. The cheapest of the line were ridiculed but usually sounded better than the flagship stuff!?! Many discussed the new version with Hyperstream X and now 8 filters probably being even better. On APs probably as that is the modern way of judging stuff. Only recently I realised none of the 9018, 9028 and 9038 based products are still in my possession except for 1 as it has them built in. Made me wonder. The products by a competitor that are hardly marketed just perform right sonically. Without Hyperstream.
So they sure seem to know how to sell their stuff. We’ll buy it anyway and do free word-of-mouth advertising despite the sometimes openly known defects 🙂 Well played! It would not surprise at all that they roam around here too.

You are the perfect customer for the ASR approved even better ES9040 😉 A New ESS DAC per year. No per 6 months.
DACs with ICs by other manufacturers stay a multiple of time in my rack I notice 😀 ESS based products are so volatile that maybe they should build in planned obsolescence. HyperEOL IV.

I don't knowif it is significant, but Stereophile ranked a Cambridge with a cheap ESS with voltage output (op amp inside) & ESA liked the DAC too (less than 500 euross).
Got an old Auralic Altair locally for the price of fish & chips cuz the wifi card ($10) was acting up. It has the cheapest 9018 and I actually quite like the way it homogenizes in the bedroom. I decided to mess with it because I like the app interface and my 10TB HDD filled with music was gathering dust for too long . $25 Aries Mini was homogenizing too much 🙂. Weiss 9018 (202) sounded quite spectacular when I heard it years ago at friends house. Just like Raal tweeters .
Jean Paul., don't you have one for the price of shipping on your shelf ? Jokers online still ask up to $3k for this artifact..
New Weiss based on ESS chips sells like a hot cakes. It's just a chip..

Not wanting to drag down the brand but it is good that they are external as you apparently need to replace them every year (the new IC does sound better….). In all honesty I feel like a donkey for having tried out so many ESS based products. First I think external is totally unneeded and secondly I feel I don’t listen to music at all when having whatever ESS based device. With exceptions, usually the cheapest of chips. I had MXN10 and that one was good (but it lacked a display). MXN10 does not need the totally superfluous external stuff.
It is something when you discover the most used feature of that new DAC is the power on/off button 😉

It is everybody's favorite punching bag, that chip , but I really wouldn't mind this $7k Weiss Dac . Even their $3k with $3 Wall-wart PSU would do according to exctatic reviews everywhere.
