I've got mine already and I do really like it.

It sounds not that horrible ;)

My post in the German forum:

Is it only me who thinks it looks kind of like a turret from the Portal-games? =) I hope it wont do the same thing to me while walking into the room however 😁

😁  indeed!

Never seen this from this point of view...

pure snake oil ,,I have a 50k linn klimax system and use the supplied cables plugged into the mains,the owner of the shop who is also a bang&olufsen dealer,is a personal friend and has top of the line b&o and linn in his house, and uses standard leads,when he has access to all the fancy leads and conditioners in his shop to take home?

Haven't you seen before and after measurements of good isolated power supply with same amplification output devices vs one with switching power supplies? Plus ever wondered why would the Beolab5 sport old fashioned expensive transformer based power supply versus the switching power supply in the speakers in the rest of the range? 

 

 

None of which is actual proveable evidence that a different mains cord can yield a detectable, audible difference. As an aside, the amplifiers in the BL5's are switching power supplies in all but name.

I believe when you look at the "Scans" of the beolab 5s you will see evidence of a humongous transformer. 

Exactly what have you tried to make such "informed" decision about writing off power cords making any noticeable differences at all to sound quality? 

Lol. I too own a Linn Klimax  350A system  coupled with a stepped resister based DAC along with Atcs etc and I still do believe in proper power conditioning and even regeneration. I mean come on! On bad days sometimes B&O speakers hum a little and on others they don't. Why is that? 

What supplied cables are you using in your Klimax? Have you gone on to the Linn forums? And since you currently own a Linn system you must truly be put off by the fact that they offer Dynamik power supply upgrades. 

Anyway to each his own. Look at the photos of the power cords used in the demoes of the A9. What's with the special sheath? I doesn't add at all to the clean aesthetic of the system btw. The sheath is in fact a little fugly. 

Why do hospitals need special plugs? Why are you not allowed to charge your phone using their special grade outlets? I believe in measurements then my ears pure and simple. Power cords and electrical power quality can cause huge discrepancies  in measurements. Unless you are one of those who thinks that sound quality has nothing to do with measurements then why buy any electronics from the 21st century at all if...... Hello...

I'm making no claims about whatever picture you're looking at of BL5's, I'm merely stating that each of the ICEpower amps in the BL5 are based upon exactly the same switching technology as SMPS's.

I'm writing off  power cords making any noticeable differences at all to sound quality on the basis that I can't find any documented, repeatable evidence that says they do. I'm not even talking about measurements, I mean statistically significant, repeatable, independantly adjudicated listening trials. None.......................... not one.

If I were in the business of making power cables and I truly believed that my cables made an audible difference to an audio system, I would assemble a group of golden ears that can reliably hear the difference (10 should probably be enough, from any of the thousands out there that claim they can hear the difference), I would even pay them a fee. I would then approach any of the major Hifi publications to cover the event, and then have an independant test house design and administer the testing. Afterwards, when all results were in, I would be in possession of a certified test result, comprising real scientifically gathered data which fully backed my claims, which was then published in a leading Hifi magazine. I would finally be able to silence the detractors and sell even more cables ..... the cable world would be my Oyster, my fortune would be assured.

None ...................... not one.

Give me data and measurements that power cords do not make a difference in published measurement results and give me reasons why do labs have regulated electrical power. 

Do you even know what you believe in?

Seriously... Give me a break! Please do inform every electronic giant out there that they are making mistakes on how they are measuring equipments and please inform them that only what you think matters and that their measurements are not your "measurements". Oh yes and please do tell every stereo publication out there that heir measurements are lies. Only you know the truth to audio. Measurements and graphs are lies! Oh yes and please do rewrite physics that all electronics are not powered by electricity and will not be affected by electricity.

Im not sure where you're going, or what you're asking - all I'm asking is for you to point me to rigourous documentary evidence that these cables make a difference, either measurements or listening tests. If there is no proof then by default the null must be considered true until proved otherwise. I cant find any proof to support power cables as a significant contributer to audio quality.
