This all reminds me of the story of when CDs were first introduced and were dismissed by the so-called "golden ears" types would complain that digital quality was poor and could never match good quality analogue, highlighting Radio 3 as the pinnacle of audio quality. They went quiet when it was pointed out that what they'd been listening to on Radio 3 had, for the previous 10 years or so, been distributed from Broadcasting House to the transmitters digitally.

- Rep Power
Lol - Some of the persuasive language they try and use as in store techy/sales employees is hillarious.

I'd accept that a "perfect" LP would technically produce "better" sound than a "perfect" CD. However, LPs were seldom perfect, even fresh from the cellophane sleeve, and they were almost immediately covered in dust that produced hiss, and electrostatic crackles. (Never mind the warped copy of my Beatles Red Double album ) Far more disruptive to my listening pleasure than quantization effects at 44.1kHz.

Converting from analogue to digital is inherently lossy. Even if recording direct to digital - as microphones work in analogue. Whereas, if you record from microphone onto an analogue format then you can make it incredibly accurate - more so than digital.

The thing is, the wave is still "steppy" at 16 bits. OK, few (if any*) can actually hear this, but it IS there. 65,536 steps instead of a perfect curve.

The question is not any analogue format but LP's. A disc spinning at a fixed rate with a needle physically traversing a groove in which the signal is encoded. In the outer grooves at 33rpm the grooves will need to be somewhat different than those toward the center. And if you don't compress different portions of the signal in specific ways, you will require bass notes to have a physical width that would mean getting about 20 seconds of music on a disc. Hence RIAA equalisation and a bunch of other trickery that is often glossed over by analogue 'purists'. Physically you also have issues with higher frequencies where the physical dimensions of the needle start to limit the fidelity of the reproduction because it can't physically track the groove (it's too big). Then there is the problem of the moving mass of the stylus assembly vs the arm - the need to track the groove vs the need of the stylus to be free to pick the signal up from the groove.
So what you actually have is one bunch of engineering trickery vs another. Neither are actually capable of a 'perfect reproduction' but all other considerations aside, digital is easily capable of more accuracy since you are necessarily decoupled from the physics of the transport and can deal with the pure information of the recording.
Of course, (some) people do like the warmth of vinyl and are enthusiastic when their valve amps add their warmth into that mix. What they are liking isn't the signal, it's distortion of the signal.

In a nutshell.

If you're really forking out for an audiophile setup you'd have a treated room, likely some £2k+ Mackie monitors and some FIERCELY hifi amplifier before you'd get into even vaguely daft cables. I've read several articles that suggest replacing plastic dials on pots with wooden ones, and colouring the surfaces of CDs green to make them sound better (not kidding on any of that btw. I'll try and dig out the articles...)

WTF does this mean, "On the face of it, our Silver SuperKords may look very expensive, but put the cost of them into context. Say you have a system with a £5,000 CD player in it, which you love the sound of. But what happens when the upgrade bug bites? You might find that to upgrade your sound, you might need to invest in a player costing upwards of £10,000. Now, in our opinion, upgrading your £5,000 CD player’s mains lead to a Silver SuperKord SD II will bring about an even bigger upgrade than upgrading your player to the next model… and it’s cheaper. In that context, surely the Silver SD II SuperKords offer extremely good value for money?"

I *think* they're trying to say that if you're gonna spend £10k on a CD player, you'd get a better sound improvement by buying their cable than doing so if you're going from a £5k player. Trying to say that the CD player would get interference from its power lead.

It means that, apparently, a ~£3k power cable will make your music sound better. Because science.

How about £2500 for a record. But What does it sound like?
5th July 2013, 12:22 PM #60
I read it as being slightly more slippery than that, with lots of 'in our opinion' and so forth. I though on the same basis I could sell a magical penny that in my opinion improved sound quality tenfold when placed in the adjacent room.*
