The real shame is that the lunatics and thugs don't even use Polk speakers anymore, they are above that now.

And when folks do ask about Polks, they are told they will need "high current" separate power amps, and magical wires, to drive most of them. I'm sure they drive many people away from the brand.

Surprised Polk (the company) doesn't realize it.

I suspect they like being associated with the high end.

He believes cleaning up the power will help, but he already uses Shunyata power cords on all his components. Didn't they already clean the power?
When I saw that about the DB25 cable I had a good laugh. There is a reason while he will never participate in SBT of cables.

I am thinking about trying to hit a few shows and get enough participation to get 50-60 people through an A/B 10 round trial of Ethernet cables.

BJC would be the baseline Ethernet and then some other ~$350 Ethernet cable.

Use an audience participation system where they have an A/B clicker in hand.

Before each hour session the 10 changes are pre-rolled and time to change randomly selected.

3-4 participants at a time. Using a pre-selected play list swap out cables. Participants would know which cable we are starting with and make their selection at will. There would be no break in playback. The switching would be truly instant.

Need to see if I could get sponsors

Why limit it to just network cables? Power cords, outlets, audio fuses, burn in, cd treatments, it's all nonsense.

That's what's so funny about that forum. They don't just believe some of the nonsense, they will buy anything that comes along, no matter how ridiculous.

But one of the participants does have a paper published in a food journal! Far as I know it's never been cited though...

Ok, people can't be this dumb:

ZLTFUL posts this Wiki Article. It's pointed out in the article that perfect copies are certainly obtainable:

http://en.wikipedia.org/wiki/Generation_loss

His response:

I didn't miss anything. Unlike others in this debate, I choose to read the entire articles instead of picking and choosing what I want to fixate on. Case in point, villain chooses only to acknowledge, in the Audiophile article posted by pretzelfisch, that there may or may not be any measurable differences. In fact, you folks only seem to like to focus on parts that support your claims instead of the other parts that go against them.

As for "perfect copying channel"...yeah...I have seen "perfect" networks produce errors. I have seen "perfect" OSes spew forth errors constantly and still work well within their established margin of error. Let me ask you this, in all seriousness...if a packetized data network is perfect, why the need for error checking/error correction? Exactly.

Duh.... How can you not 'get it'?

As expected, ZLTFUL starts calling other members names, his post is removed, and the thread is closed.

The Club Polk buddy system at work.

Wanna side bet as to whether this test ever happens at all? I'm willing to wager a lot more than $1600 that it doesn't.

I found this ironymeter-pegging quote particularly amusing:

If you are going to discuss changes in spatial properties, I would expect something quantitative along the lines of "sound images at the left and right moved further out about 1 foot".

There is a fundamental problem that ZLTFUL is taking the corrections of his misunderstanding of the papers and write ups he's linking to, well, personally.

He used the term 'Degrade and Insult'.

I pointed out to him that the last paper he linked to he interpreted incorrectly:

Traces of Internet packets from the past two years show that
between 1 packet in 1,100 and 1 packet in 32,000 fails the
TCP checksum,


Then this:


After an analysis we conclude that the checksum will fail
to detect errors for roughly 1 in 16 million to 10 billion
packets.


He misses my post PRIOR to the linked article where I said applications higher in the OSI stack can do their own error checking and correction. All outside of CRC on the link and TCP etc...

He misunderstands:

Traces of Internet packets from the past two years show that
between 1 packet in 1,100 and 1 packet in 32,000 fails the
TCP checksum


In regards to the failed packets: He will not admit that in this case that TCP did it's job, caught the error and, this is key here, CORRECTED it. It's a fundamental failure in understanding.

The only way something can report the failed checksum is that it's a KNOWN failure which means it's been a trapped/caught error and again corrected.

Then to add insult to injury he conflates this with:

After an analysis we conclude that the checksum will fail
to detect errors for roughly 1 in 16 million to 10 billion
packets.


So he totally ignores the fact that the paper was dealing with Internet (WAN) vs LAN. He totally ignores the fact that if we consider 1500Kbit packets and use the 10 billion number in a LAN only, Server to switch to client vs 30 hops,

We are talking about an ONE unrecoverable error every 146484MB or 143GB of music transferred. Even at full PCM that is one totally dropped 1.5Kbyte worth of data ~225 16/44.1 albums.

And I'm denigrating someone for pointing out the math?

Now there is a contingent there that believe perfect 1:1 digital copies are nigh impossible. One teaches EE at a small college none the less.

I posted a PDF file with MD5 hash and none there will install the checksum application, download the PDF, generate the hash and post the hash file back to the thread.

You clearly don't understand magical thinking.

Science knows nothing, anything is possible, and everything matters. Got it?

Sorry this is just straight retarded... I laughed almost as hard as when I read that someone can tell a difference in sound over different USB cables!!

PLEASE!!!

But, that is 2 month away. Lot can happen in the meantime. Don't forget to breath in the meantime.
