Quick Question About an Amp

post #1 of 9
Thread Starter 
I just ordered new headphones, Sennheiser HD600's, and an Asus Xonar Essence STX sound card. I know the sound card has an amp built in, but my question is, will I need an external amp to get everything out of the HD600's, or is the built in amp on the sound card good enough?

the ST/X have a 600 ohms AMP , and the Sennheiser HD600 has 300 ohms nominal impedance , so you dont need extra amping power

Okay, thanks for the quick answer

To answer your question, yes, you'll need a better amp to get everything out of the HD600s because the amp on the STX is not great, but you knew that when you paid for it. You get what you pay for. That's not to say the STX is worthless. It serves it's purpose, but to "get everything" out of the HD600s, you'd need a better amp.

Will the HD600s run fine on the STX, sure, probably.

The amplifier on the STX is a $2.50 integrated circuit. I think that sums it up.

However, I do think it does the job pretty well since it negates me having to output to my Little Dot MKII every time I need to listen to music or play a game. It just seems like such a chore to do that. I also can't hear much of a difference between the LD MKII and the STX's amp.

Cool, thanks for the replies, I appreciate it. I'm stoked to hear the difference between on-board audio with Senn PC350's to the STX with Senn HD600's

I've not heard the audio quality of one of these sound cards, but I've just had a look at the specs, and I'd say it's more than capable of powering your Sennheisers.

As stated above... the card is capable of powering 600 ohm headphones, and that's some feat!... so it should eat the task of powering yours.

Before you invest in something you probably don't need, try it and see how it performs. My guess is it will perform pretty well

The bulk of the pcb on the card is designed around being a pre-amp to a power amplifier through the rca outs.
