For those who are intrested about the new Blaxius^2 BNC cable. First impressions here

https://www.computeraudiophile.com/...eriences/?page=15&tab=comments#comment-889349

You realise that cable has a minimum bending diameter of 20cm? Won’t make it easy to use. (And usually minimum bending is given as a radius).

I have decided to save up to buy the HMS.

Anybody knows if the optical input to the HMS is of worst, equal or better SQ when compared to the USB input to the HMS?

I think you just need to try both. With my Dave there is zero difference between USB and optical. Source is a custom PC with an audiophile USB output card.

I agree. I enjoy my optical source slightly more but they are very close and you may find USB better... Or the same

So sad ... when I play HiRes files using the Blaxius^2 BNC cable I just get crackling noise and the display of the DAVE starts to flicker. How is this possible when the M Scaler is upsampling to 705 kHz anyway? I have no problem with 44 kHz files.

Frankly, after hearing all these early reports, it seems the device is not quite ready for prime time.

Maybe it is just a rubbish cable, or you have it bent or twisted too much. My M Scaler/DAVE plays all the way to 24/192 without any hassles using the cables that came with it,

But how is it technically possible that I don´t have problems with 44kHz files upsampled by the M Scaler to 705kHz?

How do I get M Scaler to accept DSD native from Roon on Windows? Shouldn't that be possible with the Chord 1.05 driver?

 

[Jawed]

Well, there are certain things which can filter common mode noise and a better bandwidth cable is not one of these things.

Why is that?

BNC cables feeding DAVE from an M Scaler (HMS or Blu 2) vary in their sound quality, even when they are the same length. There's two variables at play here: the cable and the connectors (including quality of the assembly). Note that the quality of assembly correlates with having good bandwidth.

If the lowest quality BNC cable (e.g. the free cable that comes with HMS) sounds worse than a well made cable using high quality (high bandwidth) parts, what is your explanation?

Have you tried the other set of BNC inputs on the DAVE? I've seen that mentioned a couple of times.

Overreaction much?

 

[Jgeffen]

Overreaction much?

I guess not. In HiFi News they wrote about a quality problem with the Qutest power supplies.
HiFi News was advising to use ifi ipower instead, so it sounds familiar.

 

[yellowblue]

Same result on the other input. Just crackling noise.

 

[Triode User]

Same result on the other input. Just crackling noise.

Is this when connecting the MScaler to the Dave via the dual BNC inputs with your new cables or is it connecting something else to the Dave direct?

Galvanic isolation was added to the USB input of the MScaler because for some strange reason, the absence of that feature caused dropouts that Rob Watts was experiencing with the MScaler outside of Europe, despite the BNC outputs being galvanically isolated. I seem to remember Rob Watts mention that the JSSG grounding method defeats the galvanic isolation of his products. Could it be your playback issues stem from possibly defeating the galvanic isolation w JSSG? Someone feel free to correct me.
