HQ Player

😁 Before HQPlayer, I was using Daphile, and my Weiss INT203 was sleeping in a box for years, as dice driver is not supported by Daphile.

 

When I switched from Daphile to HQPlayer on my MacBook, I made a test with it, and I have to admit it outperforms all the other USB to spdif interfaces I own on my system (not optimized as yours 😁).

 

Weiss’s driver is in "low latency" mode, HPlayer is using PCM only at 192KHz, ext2 and NS9 and I love the sound it produces!

That's fantastic!

My Weiss INT203 also is sleeping in a box, maybe it is time to wake up it!

Filter is up to your choice.

 

Since it is a PCM R2R ladder DAC, I recommend always running it at maximum PCM rate, IOW 352.8/384k. It would just convert DSD to PCM, but I believe HQPlayer has better algorithms for that.

 

During the listening of tracks of DSD64 and in oversampling 352.8/384k I noticed in different spots an instant noise  when using different settings (DAC bit 18 or 20, Dither NS5, NS9, LNS15 and various filters in filter 1x, Nx).

This noise is always heard at the same point in the track.

If I play "direct DSD" it does't exist.
I think I gave you an idea of the problem.

Do you have an idea why this is happening?

Oh, very unfortunate that they have disabled QoS support.

How would it help EtherRegen to be a better switch? What’s missing ?

Couldn't I do QoS on one or two switches upfront the EtherRegen instead ?

I assume there is some specific parameters you’re after to be configured ?

And yes it fully supports flow-control/pause packets so it plays nice with your NAA.

@Miska DSD2048 Sinc-L ASDMEC with one of these?

You should also have 802.1p and DSCP enabled... In addition also 802.3az with cable length and transmit power sense and low power idle.

Hi Jussi, which optical NAA endpoints do you recommend for receiving 1536 kHz audio? 

 

I'd love it if my signatureRendu did this without issues, as it's my favorite endpoint, but it seems to stutter quite a bit at 1536. 

Jussi has said, although in a somewhat opaque manner, that 1536 is not possible on Rendu endpoints due to a hardware issue. If you check your server when trying 1536 you should see that it is only sending out about 60-70Mbps when the real rate should be almost 100 Mbps (1536 x 32 x 2 = 98.304). I went round and round on this with everyone from Sonore to Kitsune to Jussi on this when I first got my Spring 2 and could not make it work but I just quit worrying about it as I prefer ASDM7EC/256 over PCM.

There is no easy solution without custom hardware. There are some passive cooled Atom/Celeron/Pentium Mini-ITX motherboards where you have a PCIe slot for plugging in optical/SFP network card.

That's what I've found in my searching as well :~(

I wonder if this M.2 NVME to PCIe x8 would work with the x8 SFP / SFP+ cards. Any ideas if M.2 NVME ports support x8 speeds?

[The Computer Audiophile]

Bummer, looks like NVME is only 4 lanes (x4) and the SFP PCIe cards are 8 lanes (x8).

FireWire!?! 
 

Wow, I haven’t used that in ages :~)

 

Don't laugh, but I have a firewire 400 external HDD running that's got to be well over a decade old, right now, connected to the 2011 Mac mini via a FW800 to FW400 cable. This wasn't its first computer.

to noisy for your taste?

I’d love a solution from Solid Run but Jussi would have to create a custom image for it.
 

Not all the hardware here supports full speeds.

Jussi already has a CuBox image for NAA if that is what you are looking for.

How is that any different/better than a Raspberry Pi4, other than the obvious.

Looking for something that’s optical and will handle 1536 kHz. 
 

Right now my signatureRendu isn’t doing it.

I suggested @jabbrthis device: Fitlet2.

For FO SFP+ you need these two:

I suppose you are referring to their Clearfog device... (Again, I suggested it to @jabbrwhen it came out)

And my ClearFog Base which has a full 1GBe SFP input, and which is supported by Armenian (Debian) is still working great to this day!

 

You load the networkaudiod (NAA) deb package on it and it works like a charm.

I have HQPlayer desktop on my MacBook Pro (2012 rMBP), and ultraRendu booted with HQP NAA image.  (I have used SonicOrbitor with HQP selected too.)  My nice DAC is NuPrime Evolution, which needs ASIO driver for native DSD (which obviously won't work on a Mac).  I used to have an ifi iDSD-BL, selecting SDM Pack = none to get native DSD, but when I try that with the Evo, HQP switches to PCM.  What are my options for HQP being able to play native DSD instead of DoP to this DAC?  If I moved HQP Desktop to a Windows PC with ASIO, would HQP NAA support it, or would my only option be to go direct USB from the PC to DAC?  I can only get DSD128 over DoP to this DAC (due to max PCM rate of 384k), but I would like the option of DSD256.

Yes. In addition, HQPlayer OS on PC hardware is not using low-latency kernel, but instead realtime kernel.

Somehow, I was under the wrong impression that you were using low latency kernel in your OS... good to know 

Did you choose realtime for latency reason or for SQ reasons between the two kernels?

Some developers are telling me that differences vary from hardware to hardware and user's preference. What are your thoughts?

Yes, very neat, and the SFP board is very reasonably $$.  So we could configure this to be a Windows 10 LTSC optical NAA, for like $450, and only need an SFP(+)?   Really?
