one snoob question to ask...

does difference in digital interconnects differ in sound???

like a CD transport's digital signal to DAC's

thanks

you would think not, but it really depends on your system as a whole (source, DAC, amplification, speakers, cables, room). If it is highly resolving you can perhaps hear a difference. I doubt it makes a difference in mid range HT systems. And it won't be something you can hear very obviously either. So for HT intents and purposes, as long as the cable is not broken and properly manufactured (shielding, impedance etc within spec) cables don't differ.

However... http://db.audioasylum.com/cgi/m.mpl?forum=...ht=modwright&r=

or here.. http://www.audioasylum.com/audio/cables/messages/115776.html

or here http://www.audioasylum.com/audio/cables/messages/115763.html

the upshot is it may not be digitally measurable, but certainly audible.

My take is

1) the system as a whole should be balanced, there is no point using Nordost Valhalla i/cs (US$3300/m pair) to connect a Marantz CD63 to a Cambridge Audio amplifier... and

2) cables are the last thing you tweak after bringing your equipment to the same "level" - including treating the room (this has more effect on the sound than anything else other than speakers)
*
In other words... Digital Audio Interconnects does differ in sound.... AM I Correct to say????

There in no length of cable mention, as interconnects are merely 1metered or 2 metered pair... Am I correct to say???

there will still be a difference if i use a RM100 versus a RM1k.... 1.5metered digital interconnects. but like you say its just not "Justifiable" for a 1k cable to a RM100 CD player (illustration purposes only).... correct

what about Coaxial, optical interconnects then, does different "makes" have difference in audio quality????

If Digital Signals is either a 0 or a 1, as ppl say either u get the signal or no signal

example:::

y is it when you use a cardas interconnect, you get better bass,
an audio quest, you get better treble
maybe van del hul, a more soothing sound

what about the transparency, soundstage, depth, etc??

as describe on provided links by bro SiriuslyCold

remember HDMI also carries Digital HD Audio......

if digital audio signals can have a difference, what about digital Video signals

is it that, certain clarity, colour, contracts, picture depth....... one is missing ???? biggrin.gif

this topic.... very nice debating indeed....

my fren, a sony technician and me did confirm there is a change,

one HDMI seem to display clearer PQ than the other, and also for AQ the ambience is different

As for me i believe there is a difference,
but at the end of the day... The Decision is Yours biggrin.gif

moomoos,

Was there less noise in the images?

bro anfield, dont know whether its noise or not

one displayed blurrer pictures, and certain brightly lit spots appeared smeared (bigger...of cos not measurable la biggrin.gif )

have to use the pioneer BD to calibrate the Detail level up ( there's improvement ) but cant better the other cable smile.gif

i also did freeze frame on facial, and did swapping few times, the wreckles, facial pores ( dont know wat you call it.. mind my inglish..hehe) seems clearer.

one very good example is on the spiderman 3, when the SandMan finally gather back its figure, notice the "details" grains of sand flowing/streaming along, and when he picks up the pendant on 1st attempt, notice the expression (details on eye)
you really dont have to pause/freeze to just let it play and replay

happy experimenting !!! biggrin.gif

What type of interconnect are you referring to above? HDMI cable, optical cable or the analogue RCA cable?

i am refering to audio digital interconnects ( not coaxial, optical)

yes i know

i just want to divert the attention to Hifi cos ...
if Digital 0/1 can have audio difference between different brands....
then what about Digital 0/1 in Video quality???

get it from reputable dealer lor... so detailed eye to notice the minute difference in HDMI quality between cable but cannot notice imitation products meh?

can differentiate.....edited but imitation very difficult to tell la

until now i didnt say an expensive HDMI betters a cheapo HDMI ... correct!!!

i just stress/debate that... there is a difference!!

what i mean is if you pay few hundreds for a "pressumed original" not knowing its an imitation (you get a heartfelt erie feeling being conned, y take risk for monster)

at the end of the day, not necessary an expensive HDMI will better a Cheapo HDMI, and neither did i say a cheapo HDMI will better an expensive one

it all boils up to system compatibility

my point here is just to debate there is actually a difference in HDMI cables.. rclxms.gif

Added on November 5, 2009, 10:58 amaudible signals are much easier to differenciate

when you hear a thunder, you can roughly tell how loud it is, but when you see the lightning flashes, you couldnt tell it brighter, fatter or thinner

you just notice the flash ... correct???
but there is a difference

Ok let me see if i can convince you.

Do you know how binary (0, 1) system works?

A LCD tv is made of millions of pixels (or dots). 1920x1080(2 million pixels) for a FullHD tv
Each pixel is encoded by binaries. If you see your GC properties, there is an option to choose 32-bit color or 16-bit color, this is what represents a pixel.
32 bit means 32 (0 or 1) to represent the color that a pixel can display.

So take an example that you are displaying a fat straight line with some blur around the edges (which means grey pixels around it)
These grey pixels can never becomes black pixels which will make the line looked clearer. WHY?? Because the cable can never know what encoding to make it display a black pixel. It doesn't have a chip/DSP for such algorithm.

Similarly, if the picture is a well defined straight line with no grey pixels around it, a capalang cable can never make the pixels grey in color. At most (if the build quality is lousy), the encoding for that particular pixel got lost during the transmission and the TV will just display a weird color for pixel (white i think).

Similarly is for audio. Do you know how analog signal is encoded into digital form?
*
lets say a HD 1080p of 1920×1080 native resolution

means to say i would have 2,073,600 pixels correct !!

so it will have est 2.7million dots of either a binary 1 or a binary 0

like ppl say digital is either a 1 or 0, means you get or dont get correct

so if a LCD depends on only one digital signal of 0 or 1 to turn "ON" or "OFF" i truly understand

but now so many million pixels meaning to form a picture,

so its common maybe few thousands pixels cant decide whether is a 0 or 1, so it just passes out what it think it is or dont pass out at all,,
meaning you still get a few thousands of "unstable correct" 0 or 1 signals...

during this state of malfunction unstableness, what will happen??? you still get a picture right, but not getting the FULL picture.

Am i correct to say???


Added on November 5, 2009, 3:19 pmCables do have resistance,
maybe its the resistance that decide to let the 0 or 1 to pass thru or not or just left it idle..

looks identical correct, if yoo really count the pixel you compare you can see correct eg 2 is original signal and eg1 is the receiving signal

so what if the HDMI cable cant decide and just alters the signal... ?

cant imagine if you have 2.7million pixels

yes you could be correct, the differences is almost negligible, depending on your setup, 32" 40" 46" 52'

well mine is just different as i'm using 50" 3LCD Single gun projection TV ( well maybe old technology) and maybe on a true 1080i or full HD 1080p the difference is +/- 0.0001 to the human eye

haha maybe have to use 2 boxes, their "optical like" cable between their boxes, another 2 hdmi's from box to TV/AVR, and another one from BD player

just imagined.....( i am illusionising only)

what if BD player to AVR( how many boxes) then AVR to LCD ( another how many boxes)

phew... real "placebo effect" sweat.gif

joking only ar biggrin.gif


Added on November 6, 2009, 11:48 amif their inventors make the Optical like HDMI's like some hifi interconnects like MIT,
that has the magic box attached/bonded by wires at both ends...
then we are safe biggrin.gif

hehe! so to get best audio CD sound from BD player is to use analog ar?

good question !!!!

that again depends on the BD player and AVR (analog and Digital input modes)

if BD player, supply inferior analog components out then of course using HDMI is better

unlike the OPPO 83 SE, pioneer LX series.... the analog out, will justify itself

also how capable is the AVR circuit in its DAC for HDMI and analog tongue.gif
