What is difference between mode 6 and mode 6 light? What is used more often here on the forum? If you use diretta target deselect all other software. Mode 1 or 2 should work i think. Don't know what 6 light does. Link to comment
Ikyo Posted February 26 Share Posted February 26 On 2/21/2024 at 7:44 PM, Wladimir said: Hmm you might be right that the CAT7 cable put a lot of strain, just not on the "sound" or signal coming through that cable, but on the connector itself. And then through the resonances of the onboard RJ45 connector, the sound might appear it's sterile/edgy, but it's because of the resonances that this cable is transferring. My latest prototype of LAN cable had imperfectly rotated plugs, so I needed to twist the cable (cat8.1 / solid 22AWG), which put unusual strain on the connector and got a little bit of what you're describing. So I tried to address the resonance of the connector and this issue is solved (to my own surprise I might add). Also, have you cut the shield continuity to the endpoint with the Cat7 cable or not? IME, it's a necessity for RPI. I suppose that the 30y old cable probably doesn't have any shield and is relatively light, right? Yes indeed, a massive difference. For me, the eye opener was getting the AQ Cinnamon some years ago. Here are some of the better cables I tried (along with the Sablon Audio you mentioned, AQ not here), others are gone or went straight to trash 😁 By my observations, the higher grade Cat (granted it's meticulously finished) gives me clearer / distinctively layered / more detailed sound, without sacrificing anything. All those measurements like attenuation, NEXT, FEXT, ACR, many others and shielding could really mean something, but I'm primarily listening, not measuring. Now I'm testing some more Cat8 / 22AWG cables, then onto some more types of shielding (I have ordered a sample of shielding, which costs 1800 eur for MOQ 😅 ) or other functional sleeving, resonance control tweaks and some types of the best regarded ferrites. Once I'm done (in about 2-3 months hopefully), would anyone be interested in trying out what I consider the best according to my thorough research? I'm happy that you've made yourself a good sounding cable 👍 Just how did you come to conclusion that Logilink plugs won't fit your cable? I've fitted them onto the Cat8.1 / AWG22 cable from the same brand (Sommercable), so I find it hard to believe that it won't fit your Cat 6 / AWG23. Hello Wladimir, regarding your comments on Ethernet cables, It appear you are very experimented. I agree with you, and cannot understand why I'l not able to use the MP0048 with the CAT6 sommer cable. My point is about the sound restitution : This latest week end, I spent more time than other days to deeper listen my system restitution, as, even I heard a quality jump with the new ethernet cables, I still noticed more mediums and highs than before. seem the system moved all the bandwidth to the highs. it was specially noticeable on the females voices. To confirm this, I decided to come back to the previous old (very old! ) ugly standard cat 5e cables. All was obvious, the system came back to the proper bass/medium/highs location and less hisses on voices. My question is about : 1 - Does the sommer cable cat6 mercator a good one our audio apps 2 - Does the "easy to plug" connectors good or not, compare to MP0048 or some equivalent. I know many things subjective, but clear is the cable/connector influence. Do you have good recommandation, to restart on good basis.

Many thanks Hi Ikyo, yes it has been many times confirmed by countless users that different cables sound differently and perhaps no-one REALLY knows why. I can present certain theories, but in the end it's only your ears that should be the judge, so if you don't like the sound of it, look elsewhere. But also remember to put the cable through at least 150 hrs playtime before judging, plugs might require even more break-in (can't tell, as I don't use those). My personal take on Sommer Cable (CAT8) after the testing is that I don't like its signature neither, I find that it favors the upper mids/highs (slightly). It also looks like they use some kind of cheaper copper alloy, which is very prevalent nowadays (left on the photo) than some hardcore pure copper (sadly that cable on the right is discontinued). Regarding the plugs, I already expressed my opinion that those field plugs in my experience contribute to the sound signature you described quite considerably, for which I dumped them and started using these simple ones, with just the bare minimum material between cable conductors and RJ45 connectors. And it's not just my invention, I found this interesting idea on another forum from a different user, who claimed he tried dozens of cables with different plugs and came to this conclusion. On the other hand it's also worth pointing out that building a cable with these plugs could be tricky and requires more precision to achieve the best results. Few tips I recommend to follow: 1. Maintain the shielding of the individual pairs as far as possible (up to the threading aid) 2. Ensure the minimum possible overhang of the sorted (unshielded) conductors (above the threading aid) - around 3,5mm 3. Maintain the twist of the pairs as much as possible And lastly, you don't have to put the whole cable jacket into the plug housing, perhaps that's the barrier you encountered when building with these plugs. Just strip a little bit more of the cable jacket and you're fine. We can continue more elaborate discussion about the cables and everything in the new thread by Auke later, in the meantime I'll silently continue my work on incorporating and testing new ideas and exotic materials, how to further improve my current design.

Steviewunda Posted February 28 Share Posted February 28 Can anyone offer a summary of the various flavors of kernels - RT, EUP, 100, NOR, etc. Can particular characteristics be assumed to accompany specific designations? Or is it purely a matter of suck it and see? It would be nice if a particular type of kernel was known to, for instance, tame an inherently 'bright' system - or enhance a 'reserved' system, flesh out a 'thin' system, etc. Link to comment

Some of us keep their preferred kernel long time...

EUP - EUPhory guaranteed (improving sense of space) 100 - 100% transparent (blacker background) NOR - normalizing tonality (no more harshness / edginess) Ofc as always, YMMV. I hope you'll enjoy it as much as I do 😁 Hey Stevie, I did just that in a funny a few pages ago, but it was actually my serious conclusion after repeated listening tests (in my system anyway). Note: According to admin, in non-RT kernels, "NOR" stands for NO-RCU now. So now EUP100 is previous EUP100NOR (as I understand it). Also, you can tune the tonality with gpkernel parameters, I'm personally using 1,3,4. Link to comment
