  1. Yep @Paulssurround and I won't waste my time on this forum any second longer. Count me out - I'm simply enjoying the music!
  2. Sorry, I don't get the logic: 1. we all appeared to agree, that there is no published science on sound differences in HiFi music caused by Ethernet cables. 2. you propose that there are people who understand this non-published sience and base there opinion on it. Did I get this right? If so, I'd kindly ask those in the know to publish there science, so that it can be discussed and reproduced by others. People like Paul share their observation. I do not by into his assertion, that the sound difference neccessarily has to do anything with the cables' CAT, but I do agree that Ethernet cables have an effect on the sound of a system, as I could reproduce this result. Using a Fluke tester btw cannot answer this question, as it is testing only the cable, not its interference with other devices in the audio chain.
  3. Thats's half wrong. Gunther Sachs, who was not only a notorious playboy, but held a university degree in mathematics, published a book on this topic (which went widely unnoticed). He used data of insurance companies to search for any statistical anomalies within accidents caused by people born under the respective signs of the zodiac, and compared this data to a control group of randomly picked people. There was very little evidence found. The book was called in German 'Akte Astrologie'. I bought and read it, because I liked the scientific approach to the Astrolgy question. Before you ask: No, there are no photographs of girls in this book.
  4. Which science are you referring to? I am truly not aware of any science, that explains why an Ethernet signal on a LAN cable would not interfere with the analog signal in a close by analog device? General experience with EMI would suggest just the opposite. Have you ever seen measurements of non-tempest computer equipment in an EMI test chamber. There is a lot of unwanted signal loss radiated through the air, and also conducted by the cables. I did'nt remember this myself, when I stated that audible differences between LAN cables would be nonsense in the Linn forum. I was strongly convinced for quite some time, that there could be no difference, cause TCP/IP either delivers a correct data pattern or nothing at all. I had to change my attitude, when I auditioned different cables and heard differences despite my expectation bias that they must sound the same. Then I remembered my early days in the defense industry, and all the trouble we had with ITSEC zones. Therefore, I'd assume that the 'scientific explaination' of what hearers hear, can be found there. I have no problem with non-hearers. But I'd wish that the nay-sayers, who did not even attempt to hear just give it a try. When Alfred Wegener observed the continental drift, most scientists were nay-sayers to his idea, as he had no scientific explaination why continents would drift apart. When science advanced, his observation proved correct. Our scientific understanding of music reproduction is not at its final state yet. Elsewise, HiFi developers could predict their design with 100% accuracy. AFAIK Linn is using computer modelling in their development but they still need to listen to get it right. And after some years, they still find improvements.
  5. You answered your question. I'm fairly convinced that the transport medium is the troublemaker, not the digital music itself. As long as you transport data from one computer to another, it works fine. But putting it close to analog devices and cables, might add noise to the analog signal.
  6. How can one agree or disagree, when being asked an open question? And sitting next to me, he would need to turn to read my body language. Appears to me, like this speculation is desperately trying to protect prejudice. Anyway, my post was attemting to take the subject matter from speculation to experience. If you have done this, but could'nt hear any difference, fine. I for one could'nt hear the advertised network noise "cleansing" effect of the Melco in my home. Despite the fact, that the Melcos do sound different at my dealers studio. If you are just speculating, don't think outside of the box. There is no box, we create it ourselves!
  7. You must try Ardbeg within a Linn system. #synergy Haha, just joking!
  8. I'd also like a better explaination by Linn. Then I checked the spec of my CAT 7 cables, only to learn that the raw cabling is CAT 7. But as RJ 45 connectors are limiting the capability of the cable, the promise is only 500 MHz, which is beyond CAT 7. In the end the truth is in the listening. Having some IT background myself, I have been a strong non-believer quite some time. I just could not find a reason, why LAN cables should sound different - not unlike many jounalist in the early 80ies, who proposed one CD player modell must sound like another, as digital is the truth. But as many honourable people claimed to hear a difference, I did what a proper scientist should do: run an experiment. I bought my cheap CAT 7 branded cables, cause they were physically most different to the cables I had. And of course I expected that they would sound the same. In fact they did not. My 'insurance' against expectation bias is asking my 16 yr old what he hears, without any further explaination. He is not interested in HiFi at all, so he just listens. If his impression matches my own, it tells me something. Any theoretical explaination, if and why we can or can not hear a difference is based on a model. And sometimes the model is just not adequate to explain reality. Bang goes another theory, as my professor used to say So just listen guys!
  9. Thanks for pointing at the Lejonklou @DavidHB. Their MM pre-amps obviously gained a lot of appreciation. Unfortunately, Lejonklou appears underrepresented here in Germany. So I never had a chance to hear one with my own ears. But I just checked their website and saw that Scala in Aarhus, DK appears to carry Lejonklou. As I'm a regular visitor to a conference in Aarhus, this might be an option. Just have to wait for November, and stay long enough on Friday to give it a try. In addition, I'll discuss the Lejonklou question with my trusted dealer. I know, that he knows the guys at Scala in Aarhus. Maybe he auditioned th Lejonklou himself already? Did you audition a Uphorik vs Lejonklou, before you obviously went for the latter? Or was this just based on the price difference? As I already own the Uphorik, any change should bring an improvement in SQ. After this semi-official announcement of mine, Linn has now a couple of months to react in order to keep my all Linn system an all Linn system To carry on speculating on a MM Urika II: if we know which ADC Linn is using, then we might find specifications somewhere on the web?
  10. Haha, then the cable with the biggest number on the price tag must be winning! Seriously, if we agree that the sound differences are caused by EMI/EMF, than the results may differ widely with the respective situation in any given setup - and also between different cables with the same CAT value. Thus, I'm not sure if a cable that works in my system, leads to the same result in other systems. Still, shielding might help to better define what's inside and what's outside of the cable. When we ignore EMI, then there is clearly no need for higher CAT cabling.
  11. The optical line itself is definitely not prone to distortions by EMF, but the converter and the CAT cable to the converter are still an achilles heel.
  12. Back in the old days of vinyls and analog there was a HiFi manufacturer who claimed: "If it sounds better, it is better."
  13. That's exactly the way I'm thinking right know. I was chewing on the question, whether to rob my bank accont to go for a Klimax Radikal & Urika II, as the discount is quite attractive. But looking into a future with less budget (thx @Smokestack), makes me wonder, whether I would regret the trade-in of the Uphorik later on. @sunbeamgls threw in a nice idea, but bypassing the first amp in the Urika II would require some capability in the hardware - which probably is not there as yet. So, I'm probably going for the Radikal w/o Urika II ,and get a XLR T-Kable instead, to get the most out of the Uphorik.
  14. Interesting warning by Linn, but their main point - as far as I understand - is, that Cat 7/8 maybe detrimental to the length of connection. Well, I use a 1m Cat 7 Exakt link between KRDSM and AEbox6. It was a truly cheap cable (less than 2 €), and buying it was provoked by my not-believing in sound differences of LAN cables. I proved myself wrong, switched on brains, and knocked my head at the wall, as I could have known better. (I worked in the defense industrycearlier in my life, and was well awar of EMF and ITSEC issues). All I can say from auditioning using tune-dem: the CAT 7 sounds better than my previously used 5/6 cables. There is a clear direction dependence. I verified my results, by getting my 16 yr old in, who confirmed what I heard, without being influenced. Meanwhile, I had the opportunity to compare my CAT 7 vs Melco cable and a (lower-end) Chord, and both went back to the dealer, as the difference did not justify the extra money. Linn's warning may hold with longer Exakt link connections, though?
  15. Not that much of an disaster in my home. I auditioned a Melco N1A/2 which was placed next to my Linn KRDSM vs my Desktop HD which is connected via TP-Link AV1200 powerline connectors. When I played the same song in comparison, the Melco sounded worse. The reason was, that the file on the Melco was 16/44, while the file on my desktop was 24/48. As the better software clearly outperformed the allegedly superior hardware, the distortion by the LAN over power obviously was not that much disastrous. I agree with Paul's explaination on the different sound of LAN cables though. The cables don't affect the payload (digital music signal) directly as this is protected, but EMF is an issue. Remember, we are in the microwave domain with digital music.
