New member from CT, USA. I have some questions about headphone amps.
1) I use headphones (Audio Technica ATH-900, possibly upgrading to BeyerDynamic T90s) at night to watch movies, t.v., game and listen to music. Mostly in the same room.
Game/movies (blu-rays): PS4
Music: Philips DVP3140
T.V. through the cable box.
All comes through the receiver. Onkyo TX-SR605.
Can I get a headphone amp that would cover all of these inputs? If so, I'm unclear how it connects... to the headphone jack of the receiver?
2) Most amps that I have researched look like they are marketed for use with computers. Unclear why that is/if I am looking at the right products.
I am considering something like this:

I'm considering the DAC element because I do have some audible hiss, etc. coming from the receiver.
If you have suggestions for other amps, or amp+dac combos around this price range, I'd love to hear. Not very interested in DIY.
Thanks! Excited to learn from this community.
Howdy furtherbum,
The reason you are seeing "headphone amps" that are used with computers is because those units also include a DAC, which takes the digital audio stream from a computer and converts it to analog to be amplified and played through your headphones. They can often be used as "just an amp" if you supply an analog signal via RCA or phone plugs.
I don't have any experience with high-end audio equipment, but I have been using a Sound Blaster E5 with Sennheiser HD650 headphones and Noble Audio 3U IEMs and I have been blown away by how amazing music (and 3D gaming on my PC) can sound. The E5 is also a DAC/amp combo, but I think you will need a DAC if you want to listen to audio from the PS4 (unless it has a phone plug on the controllers for use with a headset?). The E5 can take a digital optical input or connect to the PS4 via bluetooth. You can also use it as an amp using the 3.5mm stereo phone jack. I would suggest looking into the reviews for it on this website.
An amp alone is only useful if all the devices you wish to use your headphones with have analog outputs (or you already have a separate DAC to use with digital sources).
That said, I would imagine that the receiver could drive those headphones through its 1/4" phone jack on the front. You would only need a separate DAC/amp if you wanted to use your headphones without using the receiver (or if you want to use them with a portable/mobile device, like your cell phone or a laptop).
