Great, clean sound.

Works, sounds good, build quality seems fine

Excellent clear crisp sound

Works and sounds perfect

Two Month Update: Changing from 5 stars to 1 star. started to get loud crackling and hissing sounds that were at first

This is my first DAC/AMP, so I don't have a good point of reference, but I've used my headphones with a couple friends' DACs and mine sounds just as good

Great sound

the sound is truly incredible. if you're using a high end CD player costing $500 you probably wouldn't hear much of a difference...but this little DAC unit paired with an inexpensive DVD player or CD player will make the music come alive, the build quality is beautiful it has a very high end look to it...if someone told me it cost two or three hundred dollars I would believe it.

optical ..speaker output good sound.

Feels solid, good sound.

The sound is crystal clear and haven't found anything wrong yet

After about a year of ownership it developed a rattling sound when turned off.

I still give it a good review since the sound that I got over the clicks was very good and that I liked the general build quality, including the feel of the controls

I use these while working, so my expectations for awesome sound from a computer and inexpensive reproduction electronics are relatively low.

The right headphone stopped working and sound on the left ear became an ear piercing static sound

Worked for a couple hours at most before breaking, now all I get is a clicking sound.

Definitely produces good sound.

The sound is amazing and I've only got it barely turned up for great sound.

Crisp sound, powers my Sennheiser HD598 perfectly

you wont believe the sound this "bad boy" has a superb "DAC" topped by Smsl sd-793ii uses the classic dir9001+pcm1793+opa2134 classic match, can reach a good/excellent sound believe me this little in-expensive box

The sound is excellent from both CDs and Flac/Mp3/Ape files.

It blows my onboard motherboard sound out of the water

but once I did, the sound was amazing

It preforms very well, very clean sounding (no noise even at high volume) and great for games or music to give more clarity to the audio experience

If your mobo has an optical out, I would highly recommend getting this over a dedicated sound card like the SBZ or the Asus Xonar any time!

Muddy sound after 2 months of use

The THD is excellent; it's one of the cleanest sound feeds I've heard from a unit this cheap.

I've been using this dac/amp combo for about a month now and it does a pretty great job of producing clear and loud sound through my Philips Fidelio X2's

full, strong bass and the midrange sounds nice and robust

I found that I could listen to a concert blue ray disk at full volume at night without disturbing anyone and with a much superior sound by using a 15ft optical cable (toslink) to connect to my blueray player

The sound is incredible

Very good build quality and amazing sound using it with my Bluesound Vault and its optical output.
