Creative Core3D chip and the Burr Brown are substantially better than what you get with many motherboards that have bog standard onboard audio. Jan 24, at 2: Thanks for the input I’m just starting with the audio side of things. Some people are suggesting that as a beginner It would be better for me to vurr with say the HyperX cloud II as they come with bbrown in line DAC with pre-set 7.

One other question I might be getting confused but is the op-amp the amp that drives the headphones or is there another separate amp on the mobo that does so.?

Jan 24, at 3: Sep 3, Posts: Many parts make up what you might call a headphone amp, op-amp is the part responsible for amplifying the signal.

I’m sure someone like marsman can fill you in with more details if required. Jan 24, at 4: Dec 9, Posts: I don’t know that much I’m afraid opa1234 it comes to internal workings op2a134 amplifiers, other than what you’ve already said about op amps.

Rroff would be a good person to ask if the OP wants to know more about that.

Anyway; the PC SE, is a very good headset. I thought you might have been talking about the original PC in the Opa21334, but as you don’t have that already, must be the SE; which is an improvement on the first The biggest advantage over the HyperX, is the better quality microphone. That’s hurr only real area where the HyperX headsets could be better really.

Sennheiser’s microphones are very good indeed. If you want a quality microphone and can afford the PCSE, then they will be a decent choice. Rroff Man of Honour Joined: Oct 13, Posts: The headphone amplifier is rated for upto ohm headphones – I’ve not looked into it but I suspect it borwn another IC for the headphone driver and the OPA feeds into that.

Assuming the OPA was directly driving the opa21134 – at loud volume levels the PC only require around mW to drive opa21344 while in most audio configurations the op amp can output atleast mW. Trouble is, what does up to Ohm, actually mean?


Creative once claimed their SB Z, could power Ohm headphones, yet falls well short of doing the K any real justice. Of course, none of this really matter here, because we are talking about a Ohm headset, which I’m sure is quite easy to drive in comparison to the K, despite having an Ohm rating that is more than twice as much. That is always the problem with headphone amplifiers – I did edit the above to add in approx.

You’ll get headphones that have low ohm but horrendous current requirements to get any kind of decent sound out of them and vice versa like the HD series that don’t require much current but sound incredibly muddy if you don’t have enough voltage swing even broown the amp has the on paper power figures to support them. My bad, I meant Rroff!

Jan 26, at 8: The OP Amp can be replaced what would be the point of doing so? Jan 26, at Supposedly, allows for a slightly different sound signature, or maybe an improvement, depending on what the existing one is and the one you’d replace it with. I say supposedly, because it’s not like replacing headphones or speakers where the differences are much more noticeable. When it comes to op amps for example, the difference are likely to be subtle, if any at all.

There’s one thing which people hardly factor in when changing an op amp and deciding it’s better than the last one, and that’s human memory is poor when it when it comes to remember intricate sound details.

That’s why direct AB testing exists. By the time the op amp has been changed, so much time has passed, people are remembering what they thought the previous op amp sounded like.

Almost any electronics device in an analogue signal path will induce some noise and distortion into the signal and ubrr amps are no exception – different designs and manufacturing approaches can vary how that manifests in an audio signal and hence how an op amp “sounds” plus while no means a rule more expensive op amps tend to have lower levels of noise and distortion.

In theory with any decent op amp it should be below anything noticeable but in reality people do notice.

The reasons for changing would be to upgrade to an op amp that was truer to the original signal or had a signature sound better suited to your tastes in music. You will also find some bgown amps better suited to loads that require fast voltage changes and others better for driving current heavy loads.

There are other factors as well such as some op amps use crude “boosters” to achieve high slew rates how fast the op amp can react to a change in the signal voltage level which can result in a raw sound versus often people saying those with a more advanced approach sounding smoother. The OPA isn’t a bad choice, its designed for audio, doesn’t do anything unexpected and largely produces a very accurate sound but does have the signature “burr-brown” slightly thick and lazy signature and personally I think it is a bit like a musician playing the same tune for the th time – accurate but no longer involved in the music quite the same as the first few times.

Jan 29, at 4: They arrived yesterday my first chance today to try them out have them connected through the soundcard with SBX pro studio.

Tried buer in game first off they are good but had to use full volume the base sounded a little “weak” if that makes sense. If this is entry level gear what does Pro level equipment sound like. Any ideas why they sound “weaker” in games?

Jan 29, at 5: I don’t know to be honest. Could be to do with a setting in game audio or maybe the sound burd or device?

One thing you could try: If you are using Windows 10, then there’s built in sound EQ, which you could use to tweak the sound a bit for more lower bass. Best doing with games than music, because music will use much more of the sound spectrum, so elevating the bass will have an effect elsewhere, which could result in mucking up the sound.

Screwing up the sound in games should be much less noticeable when elevating the bass. Do you have opa21344 plugged into the back or the frontpanel audio socket? Also in the Windows sound control panel do you have it set to mute or lower volume on applications in the communications tab as this can play funny with some games.
