Hi,

My MOBO Gigabyte Z170x gaming 7 has the on board audio with the TI Burr Brown® OPA2134 operational amplifier, is this Amp capable of running a set of headphones with an impedance of 150ohm (sennheiser PC 350)

Thanks for the input I'm just starting with the audio side of things. have just been looking at some reviews for the sennheiser PC 350 they seem to be a reasonable starting point for a gaming headset. Some people are suggesting that as a beginner It would be better for me to start with say the HyperX cloud II as they come with the in line DAC with pre-set 7.1 surround built in. I have SBX Pro Studio will I be able to achieve the surround effect with the PC 350's ?

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.?

Thank you all for the input I'm learning all the time, I think Rroff might be right I found some more info on the MOBO on line which mentioned a separate IC/Amp for the headphone jack, hope no one minds but I have another question. The OP Amp can be replaced what would be the point of doing so?

Thanks once again for the help on op amps, decided on the Cloud II as they where on offer for £69 also as I mentioned earlier I'm totally new to the audio side and thought it would be interesting to compere the USB DAC, that comes with them, Core 3D chip and software. They arrived yesterday my first chance today to try them out have them connected through the soundcard with SBX pro studio. Tried them in game first off they are good but had to use full volume the base sounded a little "weak" if that makes sense.

Have just tried, or am listening to some streaming music now, Ohh my, have had to turn the volume down to 50% the sound is astounding I'm hearing tones in music that I have never been able to distinguish before. If this is entry level gear what does Pro level equipment sound like.

Any ideas why they sound "weaker" in games ?
