They're digital signals transmitted over reliable TCP connections - there is absolutely 0 chance of it affecting the 'audio quality' from the digital stream. Generally, all streaming services will download and buffer streams, so any network jitter is negated by the buffer. Audio streams do not require much bandwidth at all, so better quality cables etc will not affect that at all (cat5 vs c5e vs c6, c7, and c8 - this is mostly about bandwidth and reliability at higher bandwidth.) Any 'improvements' that you hear are purely confirmation bias. These devices are akin to those scam devices that tell you they're saving you electricity by having this arbitrary box plugged in and running all the time... (they're literally just capacitors that power an LED)...
I third this, any digital signal is inherently lossless - you can get hi-fi DACs and also DACs, preamps and amps which will ruin your signal, but FLAC playing over my 20+ year old, grey box, 10Mbit/s infrastructure will sound exactly the same as the same file played from the local disc!
Came here to say this, not a network engineer but did get a CompTIA Network + certification and it's just not how any of this works when it comes to steaming, music or video. With video there is still a buffer, maybe a one or two minute buffer as you stream. Every packet sent, there's another packet sent right after that asks the device "did you get this packet" and replies, "yes or no ' if it's no then that packet is sent again AFTER all the other packets are sent. Essentially it's sent to the back.of the line. If it didn't work that way any " download"or steaming" would be corrupted and missing data. Dropping packets happens over both LAN and WAN which is why these.pqxkets are sent, to.verifu all packets get to their destination. A better test would be streamer with WiFi, are there any audio differences between the two when all else is equal? The placebo effect is real. You want it to sound better so your mind plays tricks on you, at least with this device. The whole CAT cable thing is better shielding because CAT 8 is at least certified for 10Gbps and you may be able to get that over CAT5, it's just not guaranteed. It's just 8 cables in four twisted pairs, nothing has.really changed outside additional shielding for interference that slows down or causes real network issues.
I added this LAN Isilencer on the modem side (50 feet away down stairs from my streamer) and the improvement was quite noticeable, especially in the bass region. FYI, I have an EtherRegen close to my my streamer. Cleaning up my home network did improve the sound quality of my sound system.
@@AudioTnT oh absolutely, the EtherRegen was quite an improvement to the sound quality. And adding the Isilencer was another step up; no question about it; the bass notes where more discernible (from an do to a re for example) as well as gaining authority…
0.5% THD&N and 0.1% THD&N will not be visible in this way: 3:57 5:16 . The difference in 5:16 could be errors. Especially, the minimum level is not guaranteed to be correct in domestic uncontrolled SPL measurement. For example some low freqency noise you did not feel by ears could have affected the SPL reading.
I thought about buying the ifi bluetooth adapter (for headphones, since my phone does not have a jack and I have some hard to drive wired headphones which I really like) but this company is dead to me now💀
