So you reject the notion that jitter distortion causes an audible effect?

I reject the notion that there is enough jitter present in consumer-grade (ie: Best Buy, even Walmart) audio to be heard, yes. Theoretically it can cause an audible effect. Much money has been spent on eliminating the measurable, theoretical and inaudible.

Yes... just switching it into the signal path with the controls "flat" (or minimized) adds "sparkle" and "life" to the sound. But, its a very natural kind of effect.

I've really only used it to make my HD650s sound more like Grados, or HD580/600s - not much more. But... I understand it can do quite a lot more.

So I guess you won't believe me when I say that there is a very audible difference between my 7 dollar and 250 dollar SPDIF cables. The 250 dollar one employs several designs to minimize jitter. And my 6 dollar Toslink cable sounds better yet (I'm not sure, but I don't think fiber optics are subject to jitter distortion.)

If you think every digital cable will give you equal sound quality, I suggest doing some direct comparisons.

I can't recommend this one enough:

I don't think you're lying to me. I don't know what you hear, but I'm pretty sure you don't hear jitter. For one thing, the general consensus among those who hear, and those who sell expensive re-clockers to eradicate jitter is that optical is the digital cable with the highest measurable jitter. But who knows? There is so much voodoo in that little corner of audio that it is pretty hard to tell what's real and what's not. This much I'm pretty sure of: if you have a $250 coax cable and your $6 optical cable sounds better, I'm glad I spent my $244 on music. Sorry about your wallet. But take heart, you may have gotten off easy. One company I discovered in my search for jitter sells a $1000 re-clocker to remove the jitter (caused by the optical output) from a $79 Apple Airport Express. And the people who have bought it evidently hear a big difference.

Maybe Nick Charles will wander along soon. He had links to some data about jitter; I'm just going by my ears.

Sorry to rescusitate this thread but I have an EQ question and this thread seems to have the most relevent info for my needs. As you can see in my Signature, I have many different cans. I need to EQ each one a tiny bit different from the others. Is there an electronically controled EQ that has programmable " Pre-sets " similar to the EQ of say, Itunes,MWMP, or Foobar? I would like to pre-set the EQ to each can and then simply switch from one to the other as I switch cans without having to re-adjust 31 little pots.
I wouls simply EQ my media player, but most of my home listening is Direct CD.

Are you talking a software EQ? Sorry, didn't read this thread, but I do know that my DEQ 2496 does like 30 presets. Its a pro-audio device (hardware), but I love it - as long as it stays in the digital domain. I haven't used it with my headphones but use it for my speaker system with great results.

 

[boomy3555]

Thanks, I'll look into it.
I was actually referring to an EQ from my CD player to my Head-Direct EF-1 Tube Hybrid amp. The only cans that sound good from the EF-1 and CD player w/o a little EQ are the Denons.

Thanks, Just What I'm looking for

 

[GreatDane]

You're welcome. If you buy one please let us know how you like it. I wanted to buy it but decided the Aphex 204 would work better for me...of course I still wouldn't mind having it.

 

[boomy3555]

I was looking at the Aphex, but then I was going to buy a cheaper DBX 215 Dual 15 channel equalizer, The you told be about the Alesis and It's so much more what I wanted.

I'll let you know.

 

[boomy3555]

ChaChing. Dropped some scratch on the Alesis. should arrive in about a week.
Thanks again.

Now if I can only cancel that DBX 215 order before it ships.

The Behringer DEQ2496 has way more features, 24/96 and is cheaper.

I hope the Alesis works out for you!

I use the auto eq function of my DEQ2496 along with a calibrated measurement mic to do all sorts of fun stuff

Nothing like room corrected speakers and corrected Headphones to boot.
