Is 100 Mbit/s Ethernet enough for audio?

[semente]

I wish to replace my old BT router, probably with a wired-only unit.

I store my files in a NAS, upconvert them to DSD128 in a laptop with HQ Player and feed the stream to a small NUC.

NAS, laptop, NUC and switch can all do 1000 Mbit/s.

 

Is 100 Mbit/s enough for an audio-only wired network?

WIll it do DSD512?

Yes it will do DSD512, but I believe 1Gb routers are the standard today.  I would go for 1Gb if I were you.

100 Mbit/s widens the choice options for my budget.

I was thinking of getting one of these:

100Mbit per second is ~ 10MB per second if you round for link transmission overhead. You will have issues with streaming quad DSD and even double rate DSD may hiccup. Stick with Gbps interfaces

No need for gigabit for DSD:
 

	DFF size (MBytes/min)	DSF size (MBytes/min)	SACD size (MBytes/min)
DSD64 stereo	20.5	20.5	20.5
DSD64 multichannel (5.1)	61.6	61.6	-
DSD128 stereo	41.1	41.1	-
DSD128 multichannel (5.1)	123.2	123.2	-
DSD256 stereo	82.1	82.1	-
DSD256 multichannel (5.1)	246.3	246.3	-
DSD512 stereo	164.2	164.2	-
DSD512 multichannel (5.1)	492.7	492.7	-
DSD1024 stereo	328.5	328.5	-
DSD1024 multichannel (5.1)	985.4	985.4	-

Despite the renderer of my DAC is just a 100Mbps (by the orange LED shown), I can play my  DXD and DSD 256 files in my NAS without problem.

Yes, 100 Mbps is enough for DSD128, DSD256 and DSD512 playing. Take into account the processor power you would need in you HQPlayer host for reaching DSD512.

 

You would need (for stereo music) ca. 13 Mbps for DSD128 (including data and communication headers overhead), ca. 26 Mpbs for DSD256 and ca. 52 Mpbs for DSD512 out of 100 Mbps. Data for each stereo stream.

With current AV standards, you can saturate 100mps with 4K blu-ray content, which peaks up to 128mbit:

Streaming 4K like netflix & youtube has a much lower bandwidth and a 100mbps LAN will not be the bottleneck. Any consumer PCM or DSD format should be peanuts when you only have 100mbps bandwidth!
