In Reply to: RE: Shifting focus from more controversial parts - here's what's aligned perfectly..... posted by carcass93 on July 27, 2015 at 13:38:58
Anybody who has used a purpose built file render with an ethernet input would find his conclusions absurd. Especially when using a USB DAC. The USB receiver has NO idea of the files were streamed via network or were stored locally. I have had numerous conversations with DAC designers about this.
Seriously, using terms like "crushed' would lead one to believe the whole write up had the conclusion first, which was that the AQ cables are JUST fabulous, the coolest thing since sliced bread, then everything else was written to fit into that premise.
You like to comment about certain folks here posting "excrement" well this column is pure excrement.

I have no first hand experience comparing different Ethernet cables since I don't normally stream music over them. At present, I use them only for Internet access (no music except the occasional MP3 sound clip as part of a purchase decision) or downloads or file backups.
I have compared computer playback (using a sound card on a PCI bus and to several USB DACs) under the following conditions. I list them in order of decreasing sound quality:
1. playback out of a RAM disk
2. playback out of a local inboard disk via SATA
3. playback out of a file folder via a SAMBA share over Ethernet from a NAS.
I have also compared the following out of that RAM disk to various DACs. Again, I list these in order of decreasing sound quality. I haven't haven't tried all the various combinations, optimatizions, software configurations, etc. that are possible.
1. Playback of WAV files
2. Playback of FLAC files that are read-time decoded
The results do not surprise me. In each case, the choices that I found to sound best were the ones that placed the least processor load on the computer system.
My USB Regen is supposed to arrive tomorrow. I will be conducting a new serious of experiments to see how much this hides the various computer differences (all of which were bit identical in terms of what was sent to the DAC). If I am still hearing differences, I may try interposing a low powered computer to serve as HQPlayer "Network Audio Adapter" and see what this may do, but at present the 7 watt Intel Nuc is busy being a server on my LAN.

Thanks for reporting past experiences.
I def. look forward to your findings with the much buzzed about REGEN.
In these listening tests, I would venture to guess you have not used a file renderer/playback device built form the ground up to receive data via Ethernet then send out to a DAC, like say an Auraliti, a MiND, or a Sonore.
Yes, these will absolutely make a HUGE difference...quiet power supplies, light, non commercial operating systems, galvanic isolation.
Receiving networked audio on a PC is a nonstarter.
Back to you original point, having the processing done as far away from the DAC as possible is key. My NAS does all the decoding and just lets the streamer coast.
toward unable-to-be-modified hardware: we'll all be left to purchase ever rarer, more single purpose, computing devices like the Rasberry Pi. This is welcome IMO, as hobbyists & tweakers will be setting up their own transports under the principles that high performance audio manufacturers have employed for years with great success.

Just look at the most recent batch of MACs. No more user upgradeable memory or hard drives, reduction in the number of ports, and an ever more closing ecosystem.

LOL smh...
I may as well review a mechanical watch and you declare it absurd since you are playing a record player!
I read the article, and honestly, I don't understand your beef?
Ethernet cables are networking devices. So when you use a good one or a bad one it should make you network more or less robust. To think it somehow applies to someone that had taken a (cop out, I think!) approach of a local hard drive and a USB cable I think demonstrates a lot more about the person complaining than it does about the reviewer of review!

Hey! I have a blog now: http://mancave-stereo.blogspot.com or "like" us at https://www.facebook.com/mancave.stereo
They are two way cables designed to move digital signals, (packets), in two way communication BETWEEN networking devices.
A computer or single purpose networked player for audio purpose is more concerned with receiving packets, and, (hopefully), loading them into RAM.
In Carcass case, - he is onto something in regard to speed, which seems to be an important element in all cabling: (that is for high performance audio).
I think that it would behoove all of us to understand the differences between traditional two way network communications, and the principles that make for good audio applications.
Cheers,

Is this a joke? What is a good or bad cable? A defective cable will not work... Where all his other cables defective? Wrapped around florescent fixtures?
The total article was fictitious, and just written to steer people to the AQ cables. You can try to make excuses, and look for other possibilities, but anyone with knowledge of networking and audio will understand this.
I have dealt with defective cables before. A pseudo-CAT7 with shield detached in some cases will be somewhat worse than a CAT6 or even a CAT5e.
You were making some sort of weird claim about USB and trying to link it to the review.
If you have copped out and use a local hard drive and USB to your DAC from your computer, then no matter what anyone says about Ethernet to you, won't matter much.
I have been working with networks at home for more than 15 years - wired and wireless (I have fitted out the last 3 houses I own with wired ethernet). I didn't see anything in the article except "problem solved with these cables" with his video and audio dropouts.
I am pretty sure he's not a shill.
But I don't understand your outrage. Seriously. The only fault with his article was it was a bit on the long side.

""You were making some sort of weird claim about USB and trying to link it to the review.""What are actually talking about??? Do you understand that Ethernet connects to the streaming computer and the USB connects to the DAC?
""If you have copped out and use a local hard drive and USB to your DAC from your computer, then no matter what anyone says about Ethernet to you, won't matter much.""
If who is using a local hard drive? Again what are you attempting to say?""I have been working with networks at home for more than 15 years - wired and wireless (I have fitted out the last 3 houses I own with wired ethernet). I didn't see anything in the article except "problem solved with these cables" with his video and audio dropouts."
Multiply the years X 2 and the amount by several hundred...
""I am pretty sure he's not a shill."" LOL sorry...
""But I don't understand your outrage. Seriously. The only fault with his article was it was a bit on the long side.""
Nice of you to try and repair his image... Hmmm... Interesting...
But it just get worse... Let's see how this sounds...
I am an IT professional formally with Cisco systems. I claim to be an IT guru... I am a serious audiophile with a commercial website. I own well over TWO HUNDRED THOUSAND DOLLARS in Audio equipment, but I was living daily with a broken network plagued with glitches and dropouts... until... I was lucky enough to just happen to be sent these magical AQ cables... PRAISE THE LORD MY NETWORK HAS BEEN HEALED...

I see you also graduated from the Andrew Carnegie course. Let me know how well that works for you.
(In all seriousness, grow up and get some perspective on this things. It's a freaking cable, not some sort of personal validation through trashing others group fest)

I shall say no more - only that a certain device, made by a certain brand we both are quite partial to, is on its way.Oh, and I don't like calling something an "excrement" - it's just that sometimes I HAVE to, and they frown upon the word "shit" a little bit more here.... :-)

I very much look forward to your posting about your experiences. As you noted in your thread on the other forum, those posting with non-epxerience are abundant.Like you I have, I have been involved in file playback for a decade plus...but I in no way pretend my findings, across many systems and set ups is somehow definitive. Others will perceive different things..within reason.
For instance, note one poster (known well for totally against the grain preferences) posted he preferred mp3s over lossless FLAC files.

Right on.....
I have been curious about Carcass' findings regarding SQ with the file source being a few inches away from the player hardware.
Without more and needed investigation, - I have to admit that it is frustrating as it makes it less convenient for multiple & different devices in the home to share the music.
I regard this as being similar to I2s devices, - where it seems to be critical to have incredibly short cable runs.
"Asylums with doors open wide,

The fact that Part Time had network issues whose symptoms were audio and video dropouts and rebuffering that were mitigated in part by these cables - whose construction looks to be extremely thorough in the shielding - is showing a positive benefit.
If you don't have issues, you don't have drop outs, and you are happy with your aired ethernet audio and video performance, clearly you don't need to make changes.
But ... if you really have been doing extensive home ethernet networking, and have the scars to prove it, you'd know noise mitigation, and crosstalk mitigation is the name of the game.
