As a SR15 user I like the design and it is great that SR35 is Roon Ready finally and Roon ARC maybe possible in the future.

The real problem of NS's S/PDIF is missing DoP, DoP is only available on USB as I know.

Some Denafrips DACs have option to swap LR channel on DSD when using I2S, check the following link. ARES 12TH

I use 5V/1A USB port on KECES P8 to power Opti Box, it works pretty well.

Having NS for two weeks, most thing works well. The only one I missed is I can't do DoP through S/PDIF and I2S using USB storage or Roon. Only external USB DAC support DoP, most USB DACs can accept Native DSD but DoP is the only way for S/PDIF to transfer DSD.

Is 5V/1A enough to power OptiBox? Thanks.

After Roon 2.0 I think Roon ARC is a better way for DAP than Roon Ready and running Roon ARC APP on Android based DAP should be easier than implementing Roon Ready on Android. I am also a SR15 user and we all know the Roon story...... so this time I will wait for the real thing happen and I...

Will A&K support Roon ARC in it's Open APP?

@JasonNYC As a digtal transport, is optical and USB out available for Open APP and Roon bit perfectly? Thanks.

The life cycle of Chord products are usually very long so connector may not be a deal breaker but it is a concern. Mojo 2 is what it is so what I really want is new Poly lite version with: •Smaller size •One USB-C for data and charging, then we can forget Micro USB for years •Better Bluetooth...

I can't find manual on website, but according to the review, M button is for EQ and Crossfeed, so no filter function?

So we can expect Hugo 3 will still using micro USB for compability with 2go then 2go 2 will using micro USB for compability with Hugo 3 then on and on?

ACRO is for home audio so it is not DAP, it is similar Naim Uniti Atom HE or CHORD 2go + Hugo 2, but Naim doesn't have battery and CHORD is more portable. As a SR15 user I am very disappointed about never coming Roon Ready function, but now I am considering CA1000 for more home audio functions...

Poly has Bluetooth if you really need it on Mojo System.

@iFi audio The manual says when input is USB or BT, coaxial will become digital output. My problem is if sampling rate of USB is higher than 192Khz, the coaxial output will downsampling or muted? Thanks.

I notice the Coxial port can be used as digital output, so what kind of inputs does this output support? USB? Bluetooth?

The Web Page does not show any streaming function, Roon Ready? Open APP? UPnP?

Web Page According to the weg page, CA1000 also have Digital Out as "Optical(3.5mm) x1, USB(Type-C) x1", right?

Thanks for the manual. According to the manual, Bluetooth on 2go is always on, but Hugo 2 also has Bluetooth radio, which one is working actually? And I usually prevent to turn on both 2.4Ghz WiFi and Bluetooth on same device, but it looks like 2go can't turn off Bluetooth.

I also prefer to use software (TIDAL, UAPP, Roon) to do MQA 1st unfold, let DAC doing MQA Rendering. On Pro-Ject Pre Box S2 Digital I found some (very few) albums on TIDAL sound strange using MQA (Full Decoder), using MQB (Render only) is ok.

I can play 32/96 LDAC from Pixel 4 through ZEN Blue to DAC (Pro-Ject Pre Box S2 Digital). It shows 96Khz correctly but it can not show bits depth information.

Yes, my Pixel 4 also have 32 bits option, I usually let Bluetooth bits/sample rate setting matching source content to avoid additional SRC in phone.

I think ZEN Blue won't upsample digital output, you can check this by setting Bits Per Sample & Sample Rate in Android's Developer options then watch your external DAC's input info if available.

My concern is about BT and 2.4G WiFi, both 2Go and Hugo 2 have BT, so the first concern is which BT radio I use when using BT function on 2Go+Hugo 2? The second is can I turn off BT radio completely if I need to use 2.4G WiFi on 2Go?

It looks like 2YU has processing power (2000MIPS) to do digital filter or SRM or maybe Crossfeed just like Hugo 2, but it is not at M Scaler level. Maybe I am wrong, the 4 buttons on 2YU may mean different functions compared to Hugo 2.
