Yes, I could have, BUT when I am in the middle of composing a message, I often lose it, if I try to Google at that time. Unfortunately, since I am on constant moderation, often my messages do NOT even come up, until AFTER the 30 min limit is reached, and I cannot EDIT my messages, then. It was a small error, not made on purpose, and followed up on.
 
He is just playing you, Telstar. You hit a soft spot. I always wondered why SE made expensive cables for sale, even in audio shops, and yet he is so 'down' on others doing so, and over many years.

Steve is down on people making false and unsupported claims. Looking at his ads and website, I don't see any comic book physics or promises of sonic nirvana. It's not what I would spend my money on, but it's being sold honestly, which puts him (IMO) in rare company in the high end audio world and probably one-of-a-kind in the expensive cable and wire world.
 
You are correct. But did I do any grammar mistake?

No, not of grammar, but of reasoning, which perhaps could be due to English being one's second language.

You go from my simple statement of fact that to date, no one has established actual audible differences among cables (save for instances of their being broken, or too much resistance, inductance and/or capacitance), to saying that cables do not matter to me.

Yes, his cables are not expensive. He must have done some test for instance on the wooden einchmanns, or maybe it's only for the look.
Anyway, mine was just a witty remark. Nothing more and nothing less.
I quit the big "cables make a difference" mile-long thread for a reason and it's far from my intention to foment a cable discussion in here.
 
It has been covered here on this thread, but it IS controversial, and this is the wrong place to show more. My colleague, Ron Quan, just presented a paper on this at the AES convention in SF. A copy of that paper would be a good start.

Hi John,
I'll see to get one, thanks. Google found it and the abstract is very interesting. Controversial no doubt :)
So far, multitone IMD together with THD20 does a decent job, at least in 0 feedback designs.

Exactly. An important distinction that John and some others can't seem to grasp.

Thank you for the kind words.

Though given that some cables are now selling for upwards of five figures, I guess one cold say that they're not terribly expensive. :D

I'd love nothing more than to make them less expensive, however the litz wire that I like doesn't get along well with the braiding machines that produce the cotton sheathing that I also like.

It's quite bizarre.

Originally I wanted to braid over the litz wire with cotton, and then pair them up and do a braid over the pair, rather like a twisted pair cable but without the twist.

But the seemingly simple process of feeding the wire up through the middle of the braiding machine and braiding over it would mangle the litz wire.

An externally hosted image should be here but it was not working when we last tested it.


Even when I took some empty cotton braid and ran the litz wire through by hand and had them braid over a pair of those, it still mangled the litz wire, causing it to literally blow out the sides of the inner braiding.

That just blew my mind.

The only way for me to get the combination of litz wire and cotton that I liked was to opt for a quad braid (which technically is better at self-shielding from magnetic field interference) and do it all by hand.

But if anyone has a solution to the mangling problem, I'd love nothing more than to be able to offer a less expensive cable.

Wooden Eichmanns?

No. The RCA's are Switchcraft 3502AAU's and the barrels are a paper/phenolic laminate that goes by the trade name Garolite (XX grade in this case). It's basically a form of Bakelite.

I make the cables that I make because to me anyway, they sound good, look good, feel good, and even smell good.

Do they make an actual audible difference? I don't know. And there's no convincing evidence to support that they do. And at the end of the day, I really don't care. The only thing I care about is my own subjective pleasure and enjoyment.

If they sound better to me for no other reason than I also like how the look or feel or smell, that's perfectly fine with me. It doesn't change the pleasure I get from them which is the only thing that really matters to me.

So to that end, I make no claims about them beyond what they are, what they're made of and how much they cost.
