If you don't want to spend much in that area, try looking at the Magni/Modi combo, I would personally prefer it to an internal soundcard, especially if you have two computers you might be using your headphones with - but YMMV.
Be careful about frequency response charts, only use them as a very rough estimate/guide. You'll start hearing things that just aren't there!
Especially because our ears don't actually pick up sound in a "flat" response, if something measured completely "flat" on a frequency response chart, when you listened to it, it could potentially have some serious peak at around 1K to 3K, and around 4K to 5K.
So boys, what do we recommend this gentleman? His criteria:
- No preference of open/closed back
- Will have amplification in the near future
- Home/desktop use
- Over ear (Circumaural) style
- Budget: Maximum $300, would prefer to spend $140-$220.
- Needs to be quality, with a hard-hitting bass-drop.
What do we think?
I won't be using both the laptop and desktop, it's either or, but if I do get a desktop I'll probably go with them...but if I get a laptop then I'll probably go with a FiiO DAC. Also, I forgot to mention I have a FiiO E6 but I will upgrade later on.
