Is OLED burn-in a problem? We want your input on one of TV’s hottest topics!
pluto78:
Im sure a power cable is just voodoo nonsense IMO. Surely designers would incorporate basic mains conditioning as standard in audio equipment. I mean you dont think of getting one for your tv or any other electrical item so why hifi? I mean my tv that has audio AND a picture and doesnt suffer from unexpected burps and bleeps with a standard connection... I would love to see scientific evidence that a powercord works and not just the placebo effect. It seems every review I read is measured by the "mark 1 ear 'ole" which is subject to bias and convincing yourself that it "has to sound better" because you've wasted £70 on a kettle lead!
Dont slam me for my opinion I just cant get my head around it.
NAIM supply a resonable cord with all their equipment but they do make the "powerline" for further enhancements but at almost £400 this would add a significant cost to your purchase if you were buing a Pre/Power/Hi-cap setup/CD.

Pluto 78, you wish me to provide scientific proof something that I know I can hear?? Tell you what, why dont you provide scientific evidence that I cant.......................
When you post your researched theories, into why I cant hear any difference, then I will research and post mine.

one off:
er i think the point of pluto78s thread is that he wants you to explain
one off,
You are right of course. However pluto78 queries True Blue's understanding of dynamics
Increased Dynamics?!!! Its claims like that that make me think its all a placebo effect. So your telling me that a new power cable has increased the power in your amp therefore giving you more drive to your speakers and increasing dynamics as you raise your volume control? Either you dont know what dynamics are or these cables really are magic.
I admit to not understanding what dynamics really are and how one piece of equipment achieves greater dynamics than an another. If this is explained to me then I may be able to start an explanation how different cables do not detract dynamics from the sound. I apologise if my post was not clear.

Details an interesting experiment which showed that people preffered a bottle of wine depending on how much they were told it cost, although this was not related to what it actually cost.
"For example, wine 2 was presented as the $90 wine (its actual retail price) and also as the $10 wine. When the subjects were told the wine cost $90 a bottle, they loved it; at $10 a bottle, not so much"
"Previous marketing studies have shown that it is possible to change people's reports of how good an experience is by changing their beliefs about the experience. For example, says Rangel, moviegoers will report liking a movie more when they hear beforehand how good it is"
That is why the "I can hear a difference, I don't care about science" argument is bogus. If our taste buds and noses can be so easily fooled, why not our ears?

A simple power cable change wont affect the current coming in from a wall socket. Not true. All cable have impedance. This is made up of resistance (not dependent on frequency) and reactance (dependent on frequency). A cable with a high impedance will restrict the flow of current, consequently there will be a volt drop across the cable. From Ohms law, the greater the current the equipment sucks in the greater the voltage drop will be across the cable. The normally puny OEM leads are likely to have a higher resistance than dedicated aftermarket 'audiophile' cables. Therefore for a given current draw the aftermarket leads will present an easier path for the current.
Most ring final circuit in domestic properties are run in 2.5sq mm. This gives an effective CSA of 5.0sqmm (simplification made here for ease of explanation). OEM leads are in the order of 0.5sqmm - 1.5sqmm so offer some 3-10 x the resistance/m presented by the ring final circuit. We could go into reactance in a similar vain, temperature rise of cables, lattice dislocations, drift velocity and mean distance between collisons but I hope even the above demonstrates that a cable CAN make a difference to current supply to your equipment and hence its performance. Try restricting the fuel pipe in your car. The engine wants a certain amount of fuel to accelerate, the restriction says "no". Performance suffers.
Upping the power of an amp will increase dynamics through the volume range.. By using less restrictive cables and allowing the amp to get the current it wants you are upping the power and so dynamics will not be decreased.

PROOF that it works ay .... well, all I can suggest is that you TRY SOME !
If you hear a difference, then it works - otherwise, it doesn't ... for you.
Important to note that it may be different with alternative kit at a different location with differing mains quality.
If you mean only proof in scientific measurement terms then
(a) you are missing the point in regard to perception (see below) - or
(b) I would ask if you actually apply the same logic to any amp or speakers you buy? Do you only buy it once you have seen the graphs showing what it measures differently? [maybe you do, but I would be surprised!?]
Your other point on the fact that it's not included with the kit initially is perhaps a fair one - until you consider that all stuff is built to a price point. Any manufacturer will build an item knowing there is usually something that can be improved upon, so they make decisions within the budget it is planned to be sold for. It may be they change internal components, or case-work, or layout etc etc and every item they change will have a cost effect. The lead they include will also add a cost element. It's only when something is built to a 100% cost no object category that they can include EVERYTHING in the box you get.
Let's face it there is precious little kit in that bracket - and those manufacturers may think you would prefer to make such changes to your own preference, who knows.
I may be wrong, but I believe Naim (as per your example) do provide some better cabling in their higher-end kit, as standard - which means they must believe it can help for that kit.
Then we get on to the whole PERCEPTION issue.
To me - this is the most important aspect.
Our perception is actually ALL we have. We filter the world around us through a number of different things, as we take in the outside world and create our internal representation of it. 1 of these filters is our beliefs.
Simple fact is that our internal representation IS REALITY TO US !! Hence it is all we have.
If someone perceives something as sounding better - then in truth ... it is better for them - since their perception is all they have.
They don't hear a measured graph, they only have their internal representation (filtered through their beliefs - among other things) to experience their version of reality.
If you want more on this - search for the NLP Communication Model and you will find details on how we filter the outside world.
If you NEED scientific proof for something being true, BEFORE you take the step to listen to such things, then you may come up short in this regard.
It remains to be seen if that scientific proof is all you would require in order to have your perception allow you to notice a difference. You may find that you hear a difference anyway, if you take the time to try.
That said - it may be that you can obtain scientific proof that cabling works. Russ Andrews do put some graphs and stuff in their literature for noise reduction etc - this may be enough for you, I don't know.
There are examples of reviews being done, where a reviewer has listened to an amp and loved it - only to then comment on how poor the measurements came out - so perhaps there is more to this perception thing than science can dictate!?!?
If you listen and hear no change, then great, you save your money.
If you do hear a difference that's great too, as it gives you a new avenue to add further improvements to your system.
It's a win-win !!

i have no proof that any of these cables make a diferance but i do belive thay do
i have a prety average 42 inch panasonic i guss you could say its a budget tv.and i use the cheaper end upgrade cables and i no alot of people, not enthusiasts who have simaler priced tvs but nearly all of them coment on how good my tv picture looks compared to there simaler priced tvs however thay use the standered leads,cables that came in the box and i use upgraded hdmi's mains leads and mains filters.
i must admit i have played with the settings of the tv contrast couler ext but only by eye no profesional calibration.
i no this ius not proof but somthing must make a diferance at least eight people on seperat ocasions have comented on this

reggaedave:TRUE BLUE YOU DO HAVE A DEDICATED RADIAL ASWELL MIND, WHICH I DONT REGRETTABLY
Yes I do Dave (all cool here BTW), only got it fitted after I installed my Chord Power Chord. Reducedthe noise floor further and gave my system increased dynamics. TBH for the price I would recommend a DEDICATED 6MM line be run approx £120- £150
Increased Dynamics?!!! Its claims like that that make me think its all a placebo effect. So your telling me that a new power cable has increased the power in your amp therefore giving you more drive to your speakers and increasing dynamics as you raise your volume control? Either you dont know what dynamics are or these cables really are magic.
pluto78,
Please could you explain what dynamics are and how they are affected by current delivery to the source/amplifier/speaker. It may then be possible to shed light on how a dedicated supply can cause a difference in dynamics. Thank you.
Just google hi fi terminology and read up on it. A simple power cable change wont affect the current coming in from a wall socket. You mention a dedicated supply. Whats this? Your own power generator in your lounge? Its a kettle lead. The last 1m in the hundreds of feet of normal copper wiring in your home. How can changing this affect the dynamics? Upping the power of an amp will increase dynamics through the volume range but a kettle lead? C'mon!!
Dynamic power link
In some respects dynamic power is a similar measure to PMPO, but remains far more realistic. It is quoted in conjunction with continuous power outputs and shows how much power the amplifier or receiver can deliver for a very brief instant, such as when a crescendo is played in music. An amplifier with a reasonably low continuous power output can often sound quite good at reasonably high levels if it has a high dynamic power rating.
There is the definition, so yes fitting a dedicated 6mm cable will allow the amplifier to draw whatever current it requires regardless of what other current demand is the house ring main. I fail to see your point

I think that what everyone is forgetting that in the UK that most set ups require the current to pass through a tiny little FUSE...........
Power = Volts * Current so with a 13a fuse (as connected to amps) in the UK this gives us 3120Watts before the fuse ruptures.
The reason I chose to get a seperate 6mm radial installed was because:
A ring circuit is considered to be rated at 30amps (7200 watts). A ring may serve up to 100 m sq of floor area and, in theory, may have any number of sockets outlets or fused connection units connected to it. With each socket outlet is normally rated at 13 amps, as a 'rule of thumb', they are limited to under twenty outlets, it is unlikely that the variety of domestic appliances being used at any one time will exceed 30amps. The length of cable used in a ring circuit is limited to 50 metres for circuits protected by an MCB. The sockets are normally mounted flush with the wall although surface mounted boxes are often easier to fit when sockets are added to the circuit. .
High power electrical appliances (such as cookers, showers etc.) should not be connected to a ring main even if they use less current that the 30 amp rating of the ring circuit. Connection of such appliances will reduce the number of other appliances that can be use simultaneously and will lead to nuisance trips at the consumer unit.
Therefore my dedicated supply will allow my Amplifier to draw (47A x240V) = 11280Watts.
Hence my supply can ALWAYS meet the demands of my amplifier, regardless of what other appliances are being used on the ring. Hence increasing the dynamics as stated above.

I see what you are saying True, but to me a fuse is a restriction no matter how much current is takes to melt..........
I would defy anyone to not notice the difference between the standard cable on my rega apollo and the chord power chord. Im wondering how many of the poeple who doubt it so much and bang on about placebo have actually tried more expensive cables on their kit. I dont need scientific data or research to tell me it makes a noteable / audible difference to certain bits of kit i own, i can hear it with my own ears, clear as day.
my own very limited experience of power cords is they don't work. nevertheless, when i go back to a cdp i will try some on that, but i have to admit i don't think i will hear a difference. i kinda understand the arguments about the resistance etc. of a standard cable against an aftermarket one, but surely the standard one could let enough current through it to blow your amp/cdp up? that's assuming the fuse isn't there which is in place to blow before your power cable melts. also, how do current demands affect a cdp? surely they draw very small power. the rfi arguments make more sense to me, but again nearly all equipment has filtering in place to deal with this, and whats the point in shielding the last metre? and what about the wiring inside the component, surely this undoes all the good work?
for pluto, who wants to see scientific evidence that cables make a difference, you won't find any because there isn't any. although if it was possible to prove this i imagine cable manufacturers would be all over it. the stuff that russ andrews has published is flawed and i don't think can be taken as proof, it was undertaken by another power products manufacturer, so not independent, and didn't show anything in the audible frequency range. i'm obviously wrong, but it should be very easy to prove the night and day differences that many people talk about, just record with a very good microphone? i mean these microphones manage to record the differences in tone/dynamics/whatever when music is being recorded, if it's that obvious it should be easy to measure. there was a test conducted on another forum, where forum users were given some cables, from standard to very expensive, all covered in the same tape so you couldn't tell which was which, all they had to do was listen and say what they thought the differences were. this was done on a variety of systems from budget to very high end. big fail.
there are people who say blind testing is rubbish, but i think saying you need to see a cable to be able to hear it is rubbish. especially as everyone says it's your ears that are important, not some measurements.
i'm not trying to rubbish anyones opinion, you're very welcome to them. mine isn't set in stone, there are some very weird things in the world.

listen the only way to decide one way or the other is to conduct a properly controlled series of blind tests under clearly specified and agreed conditions and noone is going to do that
in the meantime if people believe theres a difference let them do so and if others dont think theres a difference then so be it doesnt really matter in the overall scheme of things especially as many of us are grappling with the god existence challenge

Ive not read everyones post just yet but let me tell you what i did today.
I went to a well known hifi dealer and had a look at speaker cables, and power cords.
Firstly lets get one thing straight, these two cables that we are talking about, are just metal and other materials, nothing fancy, just different combos of materials.
SPEAKER WIRE.
There where about 8 types of speaker wire in the shop.They came into only two catagories, copper based wire, silver based wire. qed range,chord ranges im sure. Most of them where just copper double insulated (chords), silver ones ( QED Silver anv is the ones i already have)...
Nutshell?..
Copper, warm sounding, deep bass sound.
Silver, bright, puncy treble sound.
The only cable that was any different was chord silver, i think it was called, copper cores, rubber double insulated, with a silver wrap around foil sheilding braid round it.
POWERCORDS.
I looked at only one, they had two in, both by chord, 70pound and 100+pound one. Looked at the 70pound one.
looked awesome. plug top, kettle lead seemed normal.
cable, you can see it seemed to be a twisted pair, insulated, with a silver braid sheilding, then coated in rubber.
interlude...twisted pair, this will make the electricity flow a bit better, the sheilding will stop interference, i know this because of work.
NUTSHELL..
If you want to use one of these cables, a mains conditioner should be used, this is the key item, not just the said cable. The conditioner will sort most of the rubbish out of your socket feed from your wall, continue to protect it from the conditioner unit into your amp/cd player , use this cable to get the max benefit from your set up.
3 steps to improvement,
Get such a power cord (great)
Get a mains conditioner unit (absolutely looking good here)
Install a dedicated radial socket direct from your mains board ,to feed just ouf hifi equipment (thats it, you cant do any more).
I dont think the 70 pound chord cable is worth it to me, cos i think i could create one very similar for a lot cheaper, but some people may feel its a good price and be more than willing.
Everyones ears are different, you cant say anything about anyone elses opinions because we all have different levels of hearing.
Anyway my new rega rs1s have just come so guna have a play, they look good, very exited.

i must admit i have played with the settings of the tv contrast couler ext but only by eye no profesional calibration.
i no this ius not proof but somthing must make a diferance at least eight people on seperat ocasions have comented on this
this was kinda a blind test and posibly better as nobody was asked can u see a differance thay just noticed a nice picture and comented, but maybe it was a placebo
i think the best thing to do is get one try it and if you like it keep it if you dont then send it back
and im not stamping my feet.
and im not stamping my feet.
exactly. the dealer today said i could demo anything almost (as long as i give him my credit card details), so im going to demo the chord powercord and some lengths of the chord silver speaker cable.
I too have said 'try it' and see.... no foot stomping here!
I personally couldn't give a rat's *** WHY it works, or HOW it works - just like using a light switch ... when I flick the switch, on comes the light and I can see it works, so do not feel the need to fully understand the mechanism.
Likewise - I tried some cables and heard a difference, so it didn't really matter what anyone else thinks - whether they agree, or disagree, since it's only ME who has to hear anything change to make it worthwhile for me.
I suspect / hope that you will do likewise ...... give it a go and make up your own mind - nothing ventured and all that .....
Enjoy!
And I do look forward to hearing how you get on.

war? not quite.
Power chords is not going to have a big effect without filter but a good filter is not easy to find. Tacima made good budget ones (I have 6! in the house) and Vertex made a great one. I have try many in between prices and nothing (really nothing else) make me feel like want to part with my money. not that I can't hear any different but I think if you already have a well balance system, filter block can take a life out of them.
I will demo purepower next, the design look pretty good being battery operated and all that....can't wait.
