They are attaching the OSI model and data transmission qualities to the cable. CAT 7 IS higher bandwidth than CAT5. Yes, 10G Ethernet requires Cat 6 (for short distances) or Cat 7 (up to 100 m) cabling. The 1G Ethernet most common in domestic networks is perfectly fine over Cat 5e. Also, the required cable quality depends only on the link speed, not on the actual utilised data rate. A saturated link is just as reliable as a barely used one. Link to comment

Jud Posted June 26, 2017 Author Share Posted June 26, 2017 15 hours ago, plissken said: If the preference is for loudness then it's legit. I believe in one instance it removed bias for/against gender from the equation. Were they trying to control from something else? Hi plissken - - Regarding preference for loudness, here are the headline and lead sentence for the cited article: Quote Million-dollar Strads fall to modern violins in blind ‘sound check’ Perhaps no name conveys superiority quite like Stradivarius. Do you think this was about loudness, or superiority? - Regarding the auditions: These are auditions for jobs. Blinding the auditions removed gender bias from the situation, which is a very good thing. If you were interviewing someone for a job, would you be concerned about anything other than gender bias? I certainly would. Taking the specific example of an orchestra, playing in coordination with others is essential. At one time (don't know if they still do), the Vienna Philharmonic required all its violinists to use the same bowing when playing in unison (in other words, upstroke at the same time, downstroke at the same time - kinda like absolute polarity ). So if you were setting up the auditions, you might want to set up a one way mirror or video feed to test the auditioner's ability to play in coordination with other orchestra members, while maintaining the blinding. Blinding the audition certainly makes it better at determining who's the superior player regardless of gender. But there are other qualities you want in a new hire besides gender neutrality, and so there are better and worse blind audition setups to get the results you want.

Upgrading or system building through "tasting" is a trial and error affair and good results are accidental. I'm not so "down" as you are on reports of items of equipment being to someone's taste. With all the factors affecting taste, it's somewhat difficult for me to determine from specs and the usual measurements whether a component will help my system make things sound more like "real life" to me, or at any rate, do the best job possible at not making everything sound the same. The less sound of its own a system has, the more it should allow the sound of the recording to come through. How we each perceive whether this happens is a topic of great interest to me. (As I've mentioned to you several times, I like the job my speakers do of this, while for you their frequency response *would* make everything sound the same to you through them.) So while I do pay attention to any objective reports of relevant facts about equipment I'm interested in, I also pay attention to whether people whose tastes seem to coincide with mine like that equipment. Edit: A good example is music. I certainly pay attention to DR ratings when available. On the other hand, if the DR is middling, not awful, but someone whose tastes seem similar to mine says it sounds good, then I'm more likely to consider buying it.

The owner of Jadis talks about his amps making violin concertos, strings, & small orchestras sound "right" to him. He is not interested in making Radiohead, rock, or jazz music sound good. He doesn't like trap drum-kits. He says that if you want an all around amplifier that handles chamber music and techno music well, - then go elsewhere. He's not building gear for dance music. The speakers that he "shows" with are indeed, big, & lumbering. Link to comment
