Which is the best optical cable under $300? - Page 3

post #31 of 168
Just saying, I thought $8 usb cable with my typical dell computer is better by at least a little than the optical output of my computer sound card and mp3 player, although they may be the very worst examples of optical transports lol.

Sometimes the optical output is not that bad.
I would say it depends on the system.

This statement raise my interest. As I am thinking how to output my digital signal to Corda Symphony, and iMac is my source that limited in USB and optical output. If I want to use coaxial the only way will be using something like hiface to converter the coaxial for me, but I am in confusion if the USB - Coaxial SQ will be anything better than direct USB output.

possibly your S/PDIF receiver chip hasn't been blessed by the jitter shamans(DIR9001?)...it happens.

BTW, which exact Sys. Concept cable would you recommend please? I'm very impressed by this 6ft glass toslink cable tbh: SHIN KIN - GLASS TOSLINK CABLES

some food for thoughts, apparently silica glass would be far better because of its higher bandwidth than even coax: TOSLINK Interconnect History & Basics

An often-overlooked cause of jitter is bandwidth limiting of the digital signal. Quoting from the Rémy Fourré Stereophile article "Jitter and the Digital Interface" published in the October, 1993 issue; " A word about optical links. Still using the example above with digital signals A and B, a low-pass filter at 5MHz-typical of TosLink-causes a time difference of 121ps. A 6MHz low-pass filter causes a time difference of 33ps. For adequate performance, optical links must have a bandwidth of 9MHz minimum. To operate at 48kHz and have a 15% margin for speed adjustments, the interface bandwidth must be at least 11MHz."

TOSLINK may use inexpensive 1 mm plastic optical fiber, or it can use higher quality multistrand plastic optical fibers or even quartz glass optical fibers, depending on the desired bandwidth and application.

In my opinion, the Dayton glass optical cable was a little smoother and warmer than the coax but with better sounding highs and imaging.

you will have to go far above a $600 Digital Coax maybe even all the way up to the $1,000 Tara Labs THE ONE to possibly be able to top the sound quality of Fused Silica Glass Toslink.

thanks, I'll look into it!

so it's an improvement over 280 strands glass to you? over what length? on what S/PDIF receiver? CS841x/DIR9001?
post #38 of 168
and btw, I'm not too sure that attenuation would be such a big of a deal over multi strand glass, as this chinese OEM manufacturer also does them in 30/35ft: 35 ft GLASS TOSLINK DIGITAL OPTICAL CABLE - eBay

leeperry, this is what I'm using, a 6ft one

[sonicwave glass] @ Your Cable Hookup

The price is pretty competitive even though the site charges ~$15 shipping and has a minimum $50 order. "Cables to Go" makes well-constructed cables, I've got several like sonicwave digital coax, sonicwave bass cable, and shielded cat6/cat6a cable which I dissected, and it looks very good to me inside and out.

Edit: oh yeah and the site has a fancy right angle mini-toslink adapter for $2 if anyone with a macbook is considering it, much more convenient than the normal mini-toslink adapters.

What I have done as I keep changing optical cables a lot is this:
I got a Toslink to Mini 150mm cable with a female adaptor permanently connected to my Mac's output.
This way I don't have to insert/remove optical cables into the Mac's output, it works like an optical output replicator.
I have a similar 150mm Toslink to Toslink cable with a female adapter permanently connected to my Onkyo's ND-S1's output for the same reason.
syscables made me these 2 adaptors and posted them the same day.
And they look great!

so it's not quite a deathmatch against the 280 strands glass toslink then..

who cares about the "280 strands glass toslink"? Is there some magical property in glass toslink cables that the whole audiophile community has missed?

Do you really think that a glass toslink and DIR9001 are the most important things in digital audio?

leeperry, I am sorry to repeat it also in this thread. You clearly lack any deep knowledge about jitter and how DACs work. Yet you cannot stop yourself from posing for an expert and saying to people that the xx strands glass toslink is the only way to go and that no A/B test is valid until they try the glass cable you are using with a DAC that has the same DIR9001 your entry level dac has. You also copy past the same insignificant isolated posts. You don't seem to understand that the power supply, design of the pcb, choice of components, addtional PLLs, reclocking, ... all have an impact on the sound.
Let's take the Weiss DAC2 (one of the many DACs rosgr63 has). It is a (very expensive) pro DAC with a well thought digital section. Even if didn't use what you called the the jitter shamans(DIR9001?), it has many buffers/reclocking inside that the end result is a much lower jitter and clock phase noise than any regular DAC which uses a DIR9001 without any additional measure.

Do you realize that if you worry about jitter so much that a BNC coaxial cable is the preferred way to go? The best glass toslink cables will have a bandwidth in the MHz range while the coaxial have a bandwidth in the GHz range (which more than a 100 time more).
The only advantage of optical cables is the electrical isolation, but it involves 2 extra steps (conversion form electricity to light then again from light to electricity) which increases highly jitter. Any decent transport will use a pulse transformer which will basically provide a similar galvanic isolation as toslink while maintaining a much much more wider bandwidth.

My intent is not to start yet another argument with you. And the few questions I made in this post are rhetorical as I sadly do not expect any sensible response from you.

I couldn't agree more!

you know slim, for your own good I'm adding you to my ignore list...your english is getting odd to decipher anyway.

IIRC rosgr63 said in another thread that this sys. concept cable sounded better to his ears than glass toslink, and many ppl on audiophile forums(including the links I already posted) think that glass toslink sounds awesome...and better than coax in many cases.

of course, neither all those ppl or I are worthy of your HD650 rig, your "analog sounding" coax cables() and/or your 50 karat golden ears(that's implied of course ).

silica glass optical has a much higher bandwidth than plastic, sorry for the breaking news...I can't be hassled to read your post in full in order to answer all your technical inquiries, though.

like many ppl on this forum, you're talking about stuff you haven't even heard! "oh yes, BNC coax is the **** coz I said so. Anyway, I'm too cheap to try glass toslink because I *know* that it can't possibly sound as good as my "analog sounding" coax cables"

this forum is full of glass toslink lovers: Reply to Difference between Digital Coax & Optical?- Agoraquest - Sony Forum

Both Electrical Coax (50M hz) and Fused Silca Glass (30M hz) have adequate bandwidth, but plastic conductor Toslink (6M hz) lacks enough bandwidth to get the job done accurately and with decent gear you can clearly hear the difference.

Come on guys this isn't a battlefield, please cool off.

Lee please notice whenever I post a comment I always state that these are the results I get from my system. I never imply that what I find out is applicable to all other systems.

Just my own experiences, not generalizations, or scientific experiments.

Enjoy the music and your equipment, be happy!
