content: I don't understand the purpose of this service. Everyone knows that cables have to be burnt in with the amplifier, speaker, floor, cable elevators, location, temperature, air pressure and music style they are going to be used with. Obviously they can't replicate that in a sterile shipping department.

content: Your amplifier has to be capable of producing "directed AC signal". Normal AC signal is not polarised and will not work well with directed cables.

content: Quote from: glarsson on February 27, 2019, 10:42:31 amExactly, if they run easy listening through the cables, it will sound horrible when I play my prog rock through them. And if they burned them in on prog, they would sound horrible if my friend used them to play his death metal.I think there is opportunity here for a far more specific burn in service to do these guys one better and replicate the customer's environment as closely as possible - atmospheric chambers, multiple amp and speaker brands. There would need to be a survey filled out by the customer indicating their musical preferences and percentage of each genre listened to in order to play that exact mix through the cables during the burn-in process. Or better yet, multiple sets of cables, each one optimized towards a given musical genre, for the ultimate in no-compromise sonic quality!

content: The most crazy overengineering for that purpose (speaker wire) I could find was to use 2.4mm2 PURE SILVER LITZ wire coated with teflon for that purpose. But that thing is "just" worth 70 sterling pounds plus vat per meter. You would have to tin the tips with something like a silver gold alloy for it to work well and keep coolness. But that is boring as it is approaching its weight in silver of value...

content: So out of curiosity. What is the burn in phenomenon actually from. I can somewhat understand speaker membranes stretching a little from factory fresh. And possibly amplifier electrolytic caps leakage settling. But what actually led to it being a thing.

content: Quote from: Rerouter on March 25, 2019, 04:14:49 amCaps should form properly in minutes, and speaker materials ought not to require any signal input to reach equilibrium - it's generally a result of the material "relaxing" after having been stretched or formed during manufacture. Tubes are constantly degrading, so maybe there's a change in operating bias or characteristics after a time which is perceived as "burn-in." This generally only happens in poorly-designed amps, though, because the bias should be stable almost indefinitely until the tube starts to fail.E.g.: I own a pair of Magneplanars, which are among the few speakers that actually do require some "settling" time - the phenomenon is due to the Mylar diaphragm being mechanically stretched at several thousand psi during assembly and therefore the tension is slightly uneven across the edges. It's a phenomenon called "creep" in the Mylar specification.Whether you play music through them or not, they will even out after a few weeks and the resonant frequency will drop a bit. If you don't damage or abuse them, they will not change further.My feeling is that when you hook up a system which is unfamiliar (sometimes poorly matched to the room acoustics, or maybe you just moved the speakers or had it turned off long enough that you've lost any memory of the sonic characteristics) it takes a finite amount of time for you to accustom yourself to the change in sound. It has the same effect as any putative "burn-in" but is purely psychological. There's also expectation bias: if you plug in a new doodad which you're sure is going to change the sound, you will eventually convince yourself that it has improved the sound after a period of time.

Several times I had to stop reading until I got my laughter under control.There's a bit in the middle that has some true gems:QuoteAnd did you know you also need to break in your power cables, too?Come to think of it, if "larger" signals break in cables faster than "smaller" ones, maybe we should be breaking in the cables by putting them between our household AC outlets and a heater or air conditioner. I ought to try it and write in!

So to them it is about "brands" not construction or anything scientific about the cables.QuoteThey offer returns.The market for this must be big enough and the believers for them to offer returns.Sometimes it makes me wonder whether they do have superior hearing.On an older copy of their website I see they didn't make cables but supplied monoblocks and valves:https://web.archive.org/web/20060321042837/http://www.audiosold.com/morrowaudio/products.htmhttps://web.archive.org/web/20060321042857/http://www.audiosold.com/morrowaudio/const.htmIt seems like in 2008 they went mad over cables:Moron Audio MA1 Interconnect Pair...https://web.archive.org/web/20081227082503/http://www.morrowaudio.com/ma1interconnect.htmQuoteRCA Version:Regular Price: $198.00SALE PRICE! $139.00You save $59.00XLR Balanced & XLR to RCA Versions:Regular Price: $278.00SALE PRICE! $195.00You save $83.00Those wires are tiny.

content: Shame, those look like they were really nice amps (bit expensive, but stuff like that is often considered "luxury"), now they've gone full audiofool.Those interconnect cables might as well be used as fuse wire.I don't see them surviving more than a few watts. Either that or they'd just snap under normal use, they can't be held in by more than the solder joints.

content: Those interconnects look like something I cobbled up when I was a kid and wanted to set up a multi speaker setup in the yard t scare kids for Halloween. I had some connectors of the right type but no suitable wire, so I just ran whatever thin wire I had, and indeed it was held in just by the solder joints to the connectors. I think one of them I wrapped a ton of electrical tape around to build the diameter up enough that the strain relief on the connector had something to actually grab, but I ran out of either time or tape so the rest got the quick solder treatment. Only had to last one night so I wasn't too worried.
