Hello, I just joined, primarily for the audiophile products. Looking at purchasing the NHT C3 speakers for our new living room. Space is about 15 feet wide by 33 long and they will fire long ways. Space is just for general listening, music room with all equipment is downstairs, so hoping they will fill it with sound nicely. Cheers.

will these components be able to drive this headphone?
ESS Sabre 9018Q2C dac Texas Instruments LME49720 amp Realtek ALC1220 audio codec
these components are part of my motherboard (aorus gigabyte z370 gaming 7) in the computer.
Instrument separation, overall clarity and resolution can be improved with even a cheap (USD 100) external DAC/Amp.
LME49720 amp has 23 to 26mA max output current. 6xx doesn't need much current (~8.4mA Irms 11mA peak for 110 dB SPL - that's pretty loud. ~23.6mA peak for 116 dB - that's really really loud)
The voltage supplied to LME49720 is sort of a question mark. 6xx do need some voltage. Assuming your motherboard and my motherboard grabs the same voltage rail from the psu, it'll get to about as loud as you'd want it but that's it. Any sort of digital EQ with -6dB pre-amplifying or more and you'll be asking for more volume.
In other words, you'd be at the limit of your motherboard driving 6xx. But I made some pretty big guesses and what you call loud and I call loud might be way different. Maybe your MB can squeeze out a little more voltage or significantly less- who knows.
side note: many premium headphones demand a lot more current than 6xx. also, there might be another buffer amp that isn't mentioned to supply more current. MBs leave a lot of unknowns >.>.
These are pretty good headphones and a steal at the price. I would just get them and get then add the amps at a later stage if you need them. The 580 might even be a better option.
i really just wanted to avoid having using an external dac/amp since it takes up quite a bit of space on my computer table.
i have an external dac amp lying around so i guess i'll have a go at them when the hd6xx arrives.
