Btw, did anyone have a positive experience with Type C splitters like this: https://www.promate.net/products/unisplit-c?variant=28566167388225

Looks like a clunky but cheap solution to charge a phone which does not support wireless charge while still listening to music.

I tested 2 different y-USB-c-adapters back in spring and couldn't get any of them to work properly unfortunately

IPhone-Y-adapter is working properly though

Can someone please explain the filters and what they do on a simple level? I realize this can be a complex topic. Does the slow or fast filter cause treble rolloff with a warmer sound? What about LL?

Thanks! I was seriously considering 2nd one (another brand but they seem to be 100% similar)

In short:
Fast: more edged, detailed for fast paced music
Slow: more rounded bassy
NOS: non over sampling: this one is rolling off as you said most, good for bad recordings like old metal
LL: as far as I remember a short delay and then applying the according filter
Tone: 1 earlier treble rolloff and a tad more sub bass to my ears at the cost of detail, good for modern good recorded music
Tone: 2 full frequency spectrum and high resolution good for classical music but can get tiring potentially depending on the mix

My understanding is that LL stands for Low Latency (that's an assumption, not a fact), so LL should be minimum phase filters (fast and slow roll off), and the ones just displayed fast and slow should be linear phase filters (fast and slow roll off). As FooFigher said, NOS stands for non oversampling, which should be an attempt to recreate the behavior of a non oversampling DAC (which is a trick, true NOS shouldn't be possible in delta-sigma DACs if my understanding is correct).

Linear phase filters could introduce some temporal and pre-ringing artifacts. It's more obvious (to ears) with EQ phase than it is in reconstruction filters : linear phase EQ sounds more natural (more analog I'd say), minimum phase sounds more artificial (digital). If you want to evaluate the temporal delay of linear phase reconstruction and/or EQ, recording a video clap and then re-recording it played with your settings and then opening it with a video editor should give you the delay. Should only be a concern for video playback or live performance.

Fast roll off are better for preserving the FR, and they push ultrasonic noise lower than slow roll-off - more a concern in audio engineering/production than in HiFi.

According to the person at the origin of Tone 1/2, there shouldn't be any impact on frequency response :

If you're interested for some graphical explanations about reconstruction filters of CS43198, here's the datasheet, digital filters responses start page 122 :

Don't hesitate to do your own researches on the subject, I'm no expert, and could have misunderstood some things I reported back.

I was never able to distinguish even the slightest change in audio output with those DAC filters. Tried them on different devices like the W2, A&K SE200, Topping E30, DX3. Sound all exactly the same to me

I find the tone setting to be most distinguishable combined with slow/NOS vs the rest.
Also might be that the lower voltage IPhone usb connection has a tad more lush and relaxed presentation vs more energetic from Android / PC - which can be a good thing btw, still trying to find out why I liked Traillii on W2 lately so much running from IPhone as I found W2 sometimes a bit too much in upper mids from other sources and now with IPhone it's feeling better

also interested in your impressions vs your TOTL DAPs using Odin and Solaris

In my opinion, the SP2000 outshines the W2, particularly with respect to layering and soundstage. I found this most telling when listening to classical music. But this is not a fair comparison. When deciding on the W2, I compared it to the only other similar sized and similar type usb DAC of interest to me, namely the Lotoo PAW S1. What impressed me about the W2 (hence the purchase), was the sound quality coming from such a small lightweight device.

Re Odin v Solaris, the Odin pair really well with the SP2000. They are extremely well balanced and transparent and have a great soundstage. They are fantastic for classical music. But I can also hear these attributes when using the Odin with the W2. Does this speak well for the Odin or the W2? I reckon it speaks well of both items.

I started with the Odin's in high gain and recently moved to low gain - high gain was a bit too energetic at times, a bit more relaxed to listen to with Low. Plus I find Tune 01 also helps. The W2 signature is for me on the edge of brightness and forwardness I want from a source. For me that is a balance that should work with a diverse range of IEMs.

+1 for Traillii

Do u use the stock lightning to usb c coming with the original package?

Honestly these are still packed in the box after my experience with first W2.
Am using ddhifi lightning adapter + ddhifi USB-C combo

Is this one?

 

[bluestorm1992]

I have been using the stock one without any issues, but surely many people choose to use others. This DDhifi one seems very popular here.
