Summary: I bought this sound card to replace the Realtek set-up in my laptop, and it does a pretty good job.
It's very small, it's easy to set-up, it provides powerful amplication, and has a much more accurate DAC than what is inbuilt in my laptop.
But that hiss! When I read reviews of this product I was aware of the fact that there was a slight hiss, but after testing this I think that those review understated greatly the amount of hiss that comes through this device.
Pros: Good sound quality, well designed, easy to use
Summary: This little soundcard is worth every penny you pay. It's a clean, well-designed, sturdy piece of equipment
Sound-wise, it should be noted that this DAC is very warm. It takes airy, what some may consider "cold" sound of the typical built-in soundcard in most laptops and turns it into warm, smooth sound.
Now, my personal setup is pretty warm on its own.
Summary: Hifiman HM-101 Portable Sound Card An inexpensive way to turn any USB capable computer into a hifi station.
So I received the HM101 and put it through some work.
Small, wow, comes with everything you need. It's so tiny. Key chain tiny. This is good. I like small when it comes to this because it's really portable. It comes with the USB cable and the unit itself. Nothing else needed.
Pros: Small, inexpensive, mobile, good design
Cons: Not constructed rigorously, some noise issues, bright
Summary: This was the first piece of audio gear that I ever owned when I was venturing outside of what I could get from local electronics stores. I wanted to see if this would provide any difference with my RE-0 earbuds and my friend's ATH-M50. I cannot speak for what I know now which is a lot more, but at that time I felt it was an improvement over generic computer audio.
Pros: Cheap, Portable, subtle warmth, good detail for the price
