Review: Yes. Excellent - Excellent sound, and as a desktop DAC/Amp, this thing should be fed by a USB port with some real power capacity (or at least not a portable like a tablet or phone). They seem to be able to drive my 300Ω Sennheiser to dangerous volume levels without distortion. I'm not in the habit of listening at that kind of volume for very long. I don't hear any noise or distortion at any volume, in fact - the DAC & Amp are both excellent. The build quality appears top notch, though the case is clearly an area where some cost cutting happened (it's a bit of a generic case, but serviceable). The bottom of the case has some non-slip silicone pads integrated into it. I wish it covered the whole bottom, but it's still better than nothin'. It's also nice to have an optical in. I'm not sure if I'll ever use it, but options are good. I love being able to use the push knob to pause/play skip music, and even turn the SK02 off (rather than an always-on power sink). I bought mine with a package deal that was cheaper to get an Orange knob - I'm not entirely sold on the look, but it's certainly easier to find the knob. The SK02 a bigger amp than the diminutive Fosi DS2, and is definitely louder. It also has more features. I've got both, love both - they're different horses for different courses.
Review: Excellent But Lacking One Important Feature For Me - Although I returned this Fosi Audio SK02 DAC Amp Headphone Amplifier I am giving it 5 stars because for what it is and for it's price I think it's a good value and performed well for me while I was trying it out. One of the reasons I considered this product was because of the high headphone power output and inclusion of both single ended and balanced headphone outputs. The power was definitely sufficient to drive all the headphones I own (Sennheiser HD6XX, Sennheiser 560S, HiFiMan Edition XS, FiiO FT1, Grell OAE1) although I didn't try it with some vintage 600 Ohm headphones I own. However, I returned it because I really needed to be able to see the volume level that was set more clearly than what the small led light could indicate. That single light was too vague to know where in the scale the volume was set. I have opted to choose another product that has an led screen which can constant show the volume from 0 to 99 at all times. This may not be a consideration for other people however. I also liked the form factor and design which took up less space on my desktop than the other product I ended up selecting. So, in summary, I consider this a very good product that unfortunately just didn't meet my specific needs. If the lack of constant volume level indicator and led screen isn't an issue, then you would probably be happy with this DAC/Headphone Amp.

## Features

- Compact Yet Powerful: The SK02 employs a minimalist and stylish design language. Despite its small size, it boasts mighty features. It supports DSD256 and PCM 32bit/384kHz high-resolution decoding, along with 3.5mm single-ended and 4.4mm balanced headphone outputs. Its robust power can easily drive wide range of headphones and IEMs with an impedance range of 16-300 ohms
- Stunning Performance: It features a high-end ESS SABRE ES9038Q2M DAC and SGM8262 op-amps. Its excellent circuit design ensures superior parameters with a SNR as high as 120dB, a low noise floor of only 3.7μV, and an incredibly low THD of 0.001%. The 4.4mm balanced output power reaches an impressive 1100mW at 32 ohms. The exceptional high-resolution capability and pure sound quality make every listening experience an extraordinary sensory journey
- User-Friendly Design: The SK02 requires no drivers and offers plug-and-play convenience. It integrates a big multi-functional control knob, allowing easy access to power on/off, play/pause, and volume adjustments. The unit features quick-switch buttons for high/low gain and input modes. Additionally, its colorful indicator lights enable effortless identification of the current working mode and the song's sampling rate
- Remarkable Versatility: Supports USB and optical input, widely applicable for decoding with computers, laptops, CD players, TVs, and projectors. Not only can it function as a headphone amplifier, but it can also serve as a preamp, pairing with active speakers or an amplifier like Fosi Audio V3, ZA3, TB10D amp and passive speakers to form a desktop listening or home audio system
- Exquisite and Durable: The SK02 is crafted from a single piece of aluminum alloy using CNC machining and a delicate sandblasting process. This not only gives it an exquisite appearance but also ensures lasting durability

Do you buy for sound, or to impress with your style? If the latter it's not for you. But I love the audio coming out of this box. Seriously - give it a try - the better your can's the better the sound.
