GR Research B24 AC Cord Review

BS they still bound to that ugly cable. Only tubes give them the real freedom to fly !

 

[Fidji]

You mean "further down the rabbit hole"?

yes, if you follow some of those guys through the years and all of the tweaks - probably they could buy proper high end speakers, or Porsche. Each cable change equals to " Song of Songs" love poem. You would not believe, how somebody can describe changes in the sound of cymbals, using the language of love.
And if you sum all the "veils removed" after each change, it would appear that their speakers were places behind 50cm concrete wall in the beginning. ;-)

Windmills sound airy, nuclear is bright yet warm and coal is dark sounding.

So windmills for acoustic folk and classical, nuclear for electro/techno, and coal for heavy metal?

 

[DSJR]

Chord Company? QED? Not allowed to say?

One 5* popular cable supplier was sold via a popular multi-brand wholesaler with reps who visited every few weeks. Margins weren't good on that brand, but so much was sold it kind-of made up for it...

 

[AudioSceptic]

Maybe the price for the GR power cable is indeed way too low to show those superlative benefits advocated by so many audiophile magazines. Amir, would you consider to test this one? It is sensibly priced at $ 34,999 for a generous 1.25 m length. Made here in the Commonwealth of MA.View attachment 218209

That would buy you over 600 g of pure gold. I wonder how much this cable weighs?

 

[AudioSceptic]

At least it is very nicely put together. Not this horrible construction that is B24.

I am sure one day I will test cables like that. Just as I tested their $1,800 BNC cable. There are people who are starting to pause and think whether these things do anything at all.

Really? Who are these heretics?

 

[AudioSceptic]

I was talking about total margin, not only dealer's

OK, but you were responding to a post about dealer markup.

 

[uwotm8]

if you do not get discount at least 25% for more expensive ones

Not buying cables for more than 50% of RRP. Got new AQ Chicago (actually a basic level) for 35% of local official retail price.
Honestly buying any audio device with no discount is weird I just can't imagine such blasphemy

@balletboy - Mains filters either help hugely, or in audiophool-speak, they mess up the sound, so you're at a huge audiophool disadvantage having filters in your distribution block. I'm also at a hige disadvantage apparently, because my old RD sourced solid metal distribution block is an IEC one and a once controversial and blunt in the extreme audio manufacturer stated categorically that IEC plugs and sockets were the work of the devil...

I use my Sounds Fantastic in a cupboard with AV stuff. My audio system is on its own mains phase. I bought a conditioning unit when my system was on a ring including loads of stuff, including the kitchen. I previously had a fairly basic unit, mainly for component isolation. The conditioning unit was an instant success, and a nice deal. My dealer got it in a trade-in, thought I might like to try it, which I did. It's still a current model and I could get my money back and more, thanks to recent price rises, but let sleeping dogs lie.

Never mind the arguments over power products, and I doubt ASR has recommended one that costs more than a few $, buying used products with warranty and high resale values and often keeping new and used items for 10+ years, the overall cost over the years has probably been much less than buying cheaper stuff and chasing for the next best thing. My Sounds Fantastic block is the record-holder I think it was about £30 ± when I bought it over 20 years ago, maybe less, if only for the surge protection.

But PSC+ cable with a 72V DBS system sounds better...

One 5* popular cable supplier

My bet is Atlas or Ecosse - always hated their speaker cables, such a Canare-level

Good grief...

So you don't think it makes a difference (for the signal to noise ratio) if the signal is phono level, line level, or mains voltage?
It makes a huge difference since induce noise stays the same.

and scalloping-loss can't be hand waved away when trying to measure Noise with an fft

Absolute monaural thresholds for continuous unmodulated and frequency-modulated signals were determined for five normal-hearing subjects using the method of adjustment. Three carrier signals (250, 1000, and 4000 HZ) were modulated at rates of 2 and 20 times per sec using frequency deviations of...

Three carrier signals (250, 1000, and 4000 HZ) were modulated at rates of 2 and 20 times per sec using frequency deviations of +/- 5, 10, and 20%, and both ramp and sinusoidal modulation. Thresholds measured at the slower modulation rate were 5 to 10 dB lower than those measured for unmodulated signals at the two higher test frequencies

I think most members know not to waste money on this kind of thing so isnt it a waste of Amir's time not to mention 350 dollars?

You must have heard of Google?

Anyone who googles this cable will now be able to find this review. Finally consumers have a different option than paid, sighted and subjective 'reviews'.

I'm willing to bet that is how most members found ASR and became members.

So no, it's not a waste of time and money, it helps consumers and attracts new members.

Thanks Amir for the fantastic music used in this test
Enjoy...

I call these type of cables "Heat Shrink Art", and many other names.

Actually it isn't (although the Atlas chap confirmed to us the wire itself cost pennies)

 

[mhardy6647]

I think you are on to something. Seems like no matter the gear the optimum burn in is 200 hours with few exceptions. So it makes sense if this is a property of the electrons and not the gear. Now that's what I call Science.

shouldn't there be some uncertainty in that time, or is that only true if those electrons are movin' really fast?

Cable pants. One of my favorite innovations of recent decades. Thank goodness for the inexorable march of technology!

Show me a cable with thick copper wires, quality plugs with 10A or 15A, no need for gold plating but whatever, and i will offer you 50 euro for 1m cable.

You may use such stuff for customized gaming PC, or UPS, or some other appliances in case they are very power hungry, or suffer from transient spikes on powering on.

In case you are replacing generic power cord, and it was the weakest link, you may resolve few rare issues with you electronic device, but it wont be a miracle, rather a damaged cable.

It wont change anything on audio output though.
