    The Ethernet cables, Switches and Network related sound thread. Share your listening experience only.

    What issues (if any) are you having with the network? My understanding of ARP (which I've never worked with directly myself) is that it uses almost no network bandwidth at all. There's obviously some low level of background traffic with multicast and broadcast from various things like UPNP...

    Do you have network issues? That's the first and most important question. And if you do, how do they appear, i.e. what symptoms show up? I haven't worked directly with (i.e. implemented / consumed) ARP traffic, so I have to take a pass on that one. (ARP no relationship to ARPA i.e. ARPAnet...

    You're taking this a bit too personally, but simultaneously you are assuming that a company that is trying to make money selling ridiculously over-priced antique electronic equipment using (literally) unbelievable claims and imaginary technical words is somehow completely objective 🤣 However...

    It's always hard to know what people are discussing on this thread. But if you're just trying to use a bunch of switches and routers in a row (no idea why, but 🤷‍♂️) then an unmanaged switch outside of the firewall is fine. Obviously, do not plug your mom's PC into a switch outside of the...

    I thought if that lasted for over two hours, you were supposed to call your doctor? That is an interesting opinion. Other things that don't include firewalls: Power cords. Potato mashers. Network cables. Salamanders. A switch isn't Fort Knox; it's a busy intersection with traffic going...

    To me, this is the only one that could impact sound. Allowing electrical noise through from one point on the network to the DAC would allow for theoretical degradation of the output from the DAC. This is supposed to be impossible ("galvanic isolation" is supposed to preclude this), and even if...

    I'm open minded, and I actually enjoy learning from being proved wrong. I'm not religious about my technical understanding and beliefs. (I'm just religious about my religious beliefs. God bless you.) So if you have an explanation or even a theory about how an Ethernet cable can impact the...

    I was thinking this morning about how to explain the difference between digital processing and analog. Imagine that digital processing is like watching for a certain light to be on. The light needs to be either on, or off. You can imagine someone worrying about the wattage of the light. Someone...

    No for the cable and switch (because they're digital). Buying higher end equipment doesn't hurt anything, except the pocketbook, and if it makes people happy, they should do it. I just don't like when people with money to make from selling stuff are misleading about what that equipment does that...

    Plex server running on a 12-core 128GB Mac Pro, pulling media from a 4-bay Synology NAS with RAID 5 (or whatever they call their extension to RAID 5) with 44TB (32TB net), 1TB HA flash cache, and RAM maxed out. I also run Audirvana on a Macbook Pro, pulling from the NAS. With a good NAS and a...

    I run about 20 different switches across a few different locations. Mix of brands (Cisco SMC Dlink etc.) All gigabit or faster. Some layer 3, but most layer 2. Some managed, but most unmanaged. Some 64-ports, some 32-ports, and a handful of 4- and 8- ports where I don't have enough home runs...

    It's interesting, but will make zero difference in the audio. Some packets might need to be re-sent, but that's normal behavior in TCP/IP traffic.

    Those published standards are why every stream of data that goes over a network is absolutely 100% bit perfect. Sure, you could build a network switch that "cleans the data stream" (which might mean purposefully corrupting the data in random ways, but in reality I think it's just "do absolutely...

    This is incorrect. An Ethernet switch is not allowed to "clean the data stream". There is no such concept to begin with. Don't take my word for it; you can actually read the specification for yourself: https://standards.ieee.org/ieee/802.3/7071/ DACs simply translate bytes in RAM (not "on the...

    MrSpeakers Ether CX - $899 from Massdrop

    That must be it, because my HD600's (from Drop, FWIW) are pretty tame for bass compared to my Ether C's (not from Drop). But the Ether C's are definitely NOT bass heavy. They seem very natural sounding to me (and they have since I first tried them), but I don't really stop and think about it...

    MrSpeakers Ether CX - $899 from Massdrop

    The bass is reasonable, but definitely not overwhelming (as is the modern style). I haven't had to EQ these at all. These continue to be my favorite closed back headphones (I use these in the office), and it's not even close.

    JH Audio Layla Impressions Thread

    JH sells some cleaning kits etc. but I've never had wax show up in mine so I've never had to clean out the bores. (I don't personally get any wax buildup in my ears. And since my Laylas are custom fit, I don't have to worry about anyone else wearing them.)...

    Shanling H5 - Portable DAC/AMP/Player, AKM AK4493S DACs and sweet warm tuning

    It must be mostly battery, right? It's definitely larger and heavier than I'd like.

    Shanling H5 - Portable DAC/AMP/Player, AKM AK4493S DACs and sweet warm tuning

    The question that I have is fairly simple: Can I use an iPhone plus this (connecting via bluetooth, I assume) as a full function audio player, with the H5 holding the music (1TB micro SD for example) and doing all the DAC+AMP work, sitting in my pocket, while I control it completely via the...

    JH Audio Layla Impressions Thread

    I had considered flying down to do just that ... spending $4k on IEMs compared to spending a week in Orlando, the IEMs are obviously more expensive. My fit wasn't 100% perfect, but it's pretty good. Sometimes it takes 30-60 seconds of fiddling to get the seal that I want. (I don't use any of the...

    Audio streaming is async and uses such a small amount of bandwidth that any wifi AP from the last 15 years should be able to carry it without the slightest concern. The only issue with wifi is that it is electromagnetic, like actually-on-purpose throwing out electromagnetic waves, so there is...

    They are the best isolating cans I have. They are the only wired cans that I have that my office mate does not complain about sound leaking out of.

    That's an interesting question. In both cases, if the audio signal is coming out of the streamer, it must be using the same DAC, so somehow that DAC is getting fed differing music streams. I don't really know much about that, though.
