Sound Blaster Z: :Terrible Audio Quality - Page 2

post #11 of 19
Hey Airmanator,

I think I have roughly the same problem as you. I believe it has to do with the output impedance of the headphone out on the SBZ. Your Senn. HD555s are rated at about 50ohms, according to Amazon, and the SBZ headphone out has a ohm rating impedance of ~32ohms. According to "the rules" you will encounter weird frequency mess-ups when you go over 1/8th of you headphones ohm rating. So 50/8 is about 6.3, meaning that the headphone out is ALOT higher then what it should be. I am running AD700s right now with an ohm rating of ~32ohms and get some really grating vocals when listening to music or youtube videos.

What you should try is hook up your headphones to the line out>set SBZ control panel to speakers and see if the really terrible audio persists. You can mess around with the different speaker modes too. I have been messing around with it recently and voices no longer give me the ear bleeding feeling, although it can just be placebo.

What did your EQ graph look like before?

There seems to be some confusion in this thread with sound quality and equalized sound.

If the eq is what you are talking about op then that's not sound quality. That's your preferred response curve.

And cuad, according to you 90 ish snr and 116 snr makes no difference apparently..

Well if you think your conspiracy theories are correct, then tell me using stereo direct(Sbz), where its only the DAC, no spu vs realtek alc with sound enhancements off is the same quality. More audifools I guess.....

P.s. Sbz headphone impedance out is 20 ohms. Even with the 1/8 rule being broken, it shouldn't sound terrible to the extent he's talking about. Most people never even notice it.

SBZ has ~22ohm output impedance (headphone jack).
And line-out is specced to have 100ohm output impedance. Not sure if Creative put the 100ohm output impedance to the front speaker jack.

Watsaname (hi again), get one of these and connect it your headphone out. I can't totally guarantee it'll work perfectly but for something that cheap it'll certainly help you a lot.

Misspoke about the 32ohms, don't know where I got that from then...

EDIT: SaLX, yeah thanks. Trying to save up for a Audio GD 15.32 and a new pair of headphones right now so I don't want to spend the extra money, but I actaully have a Fiio E07k that I've had for a while, just no long 3.5mm to 3.5mm cables to hook it up.

@salx

^+1 for that advice. Definitely worth the few bucks to help out the impedance mismatch.

If I'm following you correctly, I insert my jack into one of the ports for speakers instead of for headphones? Might be worth a try.

As for the EQ graph, I'd have to reinstall my Realtek software and drivers, but I see where you're going with that; I could just copy the EQ from there to SBX and see what happens. I would've never have thought of that on my own.

Hello sirs. I have the Sound Blaster Zx card on my new computer. I run it with Superlux HD681B (2x32 OHMS) headphones and Logitech Z623 (THX rated) 2.1 speaker system with the new Sound Blaster software and drivers.

When I upgraded the sound card (being the final piece of those 3 that I got), I immediately noticed massively superb and better sound quality to the motherboard (Gigabyte GA-Z87P-D3) integrated RealTek sound. The sound was also really loud in a way that from the lowest (off) setting, the slightest move of the slider to more sound was quite loud, clear and crisp, and the bass was massive.

One day however, while having done nothing, it seems something went wrong. The card reports no errors and all pieces of equipment work. However it seemed the sound went much more quiet and dull. Both on headphones and on speakers. Especially the speakers now suffer as it seems that the card does no longer utilizes the subwoofer. The sub makes sound, but it is like it is missing range. If I deselect the subwoofer altogether from the control center, then the bass becomes much better(!).

But the sound altogether used to be great and the volume used to be high. Now even if I switch the red control slider thingy on my table to max, it is not "enough".

The day I noticed all this was quite a clear difference and I thought the cords were not well attached or something, I even reinstalled drivers, reconnected everything, re-attached the Zx card too. To no avail.


Could it be that the AMPLIFIER of the Zx soundcard has gone broken somehow? Could the card have "busted out" somehow? I mean I still get good sound but it is just not the same. And since it is not just the subwoofer, I think it must be the card. Or should I return everything? (I got 1 year warranty on everything still standing)

P.S. I have had the RealTek card disabled on Device Manager since day 1. And of course I've been playing only lossless .wav or .flac music files, or watching DTS sound movies..

Thanks for the help.

1. Can the Zx headphone amplifier get busted with the sound still working?
