Fosi Audio ZD3 Desktop DAC Preamp, Fully Balanced Digital to Analog Audio Converter with ES9039Q2M for Home Stereo Amplifier, Bluetooth/USB/Optical/Coax/TV HDMI ARC Input, XLR/RCA Output with Remote

ZD3 from Fosi Audio is a great DAC and preamp all in one !Build quality is top notch , connectivity and ability to integrate with systems is awesome specially due to unique HDMI connection.I have used it thru Coax, Optical, USB and Bluetooth connections and ZD3 is producing great sound quality punching well above its price point , totally unthinkable just few years ago .I have it for 2 weeks now and after 50 hours of use it opened up to a really wide and deep soundstage with clean tonality and very musical presentation. Stock TI Op amps produce very clean and clear sound character while included NJR Opamps are more warm and lush in tonality . Both are great choices and picking one over the other maybe up to the rest of the system or room acoustics as deciding factors.Bass is almost sub sonic with TI op amps and NJR Opamps are more bloomed in mid bass making them a better match to some bookshelf speakers where mid bass is very important.Detail and resolution coming out of ZD3 is fantastic .I have to say that adding audio grade Linear Power Supply with 12V and at least 2amp of output really transforms ZD3 . I have Ali Express sourced 55usd LPS that allowed the soundstage to further open up , bass be more articulate and less bloated , highs have lost some shrill and are much cleaner and convincing as well , same for harmonics with all acoustic instruments that are even cleaner and better extended in timber and ring to them .I highly recommend Fosi ZD3 in it's stock form , further use of other dual op amps or discrete ones maybe the best way to tune it to your liking . Op Amp swap took me 5 minutes after watching the instructions on you tube , it is very easy , it really allows this DAC to be fine tuned to your system and sound type you like. Fosi Audio is highly praised for this design and unique ability to match up with your expectations .I look forward to listen and own more of their gear and will keep my eyes and ears wide open to their other products!!!Great job Fosi , keep it up .

Even though it didn't work in my situation. This is an excellent DAC/Pre-amp. It is an excellent pairing with the Za3 amp, which I will be keeping. Very rich and clear sound, easy to use, a lot of inputs including HDMI-arc.The things it needs for my setup is room correction and tone controls. I have a unique room with many challenges. I wish this would have worked, but it is boxed up nicely and comes "as new" so don't be afraid to grab it from the Amazon warehouse if you see it there in the next couple of days.

This DAC is excellent. I've been using a different DAC for a number of years, but it was having issues. I decided to try the ZD3 as an upgrade and it's such a huge improvement. The sound is much smoother, yet more detailed than my old DAC, and there is a noticeable reduction in noise. My only gripe is that when you use the switch to defeat the volume control, the volume display number still works. The volume doesn't change, but the volume display functionality is still active. I would have preferred that they just hide the volume number when the volume function is disabled. It's a really minor gripe, and should not discourage anyone from buying this excellent DAC.

This is an excellent DAC.It has many features that you only find in much more expensive units.I like that this has balanced XLR outputs.They include another set of op-amps you can swap out which is cool.For me the original op-amps that Fosi chose to install as default sounded better but it's nice that you can roll op-amps in this DAC.This DAC sounds great.It sounds very clear and detailed.This pairs perfectly with my Fosi ZA3 amp as this has the balance XLR outputs which allows me to utilize the balanced XLR inputs on the ZA3.This also has the 12V trigger out to trigger that ZA3 amp.The Bluetooth connects very fast and I don't notice any lag in the audio when watching videos or movies which is great.I love the look of this stacked with the ZA3 amp.The only thing I wish it had is tone control to adjust the bass and treble to adjust the sound.I like to tweak the sound based on the speakers I'm using so it would have been nice to have some tone control.For all the features you get at this price, they hit really it out of the park with this one.

Very nice, fairly inexpensive DAC. Sounds very clean and smooth!

Item is as described. Very easy to setup! Does a great job! I have it setup with the Fosi ZA-3. Sounds great! Multiple connections for all your other audio inputs. It will connect to one Bluetooth item at a time. I have my TV, phone, and tablet setup to use it on Bluetooth. It will surprise you. I also am using a cheap Sony dvd player as a CD player to play my cds. Sounds excellent! Get the balanced cables to hook it together with ZA-3. Simplified the cable setup. Overall very happy with it!

I was curious as to the great reviews this dac was getting and I wanted to try a good sounding dac that could be upgraded. The bypass switch on this unit really nailed it for me. It was wonderful! Super detailed and clean. I tried hooking up the dac to an outboard linear power supply and the combo edged out my other dac that cost several times the amount spent on the power supply - fosi combo...wow! 5 stars for cost and performance.
