More inputs, better op-amp chips and most importantly, it can be used as a DAC on a HiFi system. DAC, digital to analogue converter, is the device that translates digitally stored information from a PC, mobile phone or other such device into the analogue sound that we can hear. Generally, a DAC can improve sound quality.
I have been using this DAC for a year and a half. It has been dead reliable besides the the port being damaged on the first one I got from Amazon. I use it with my HD 58x Jubilee and it has no issues whatsoever, always sounded good. It is full aluminum and the nobs are premium. Good deal for a headphone DAC.

Connect it to the "Audio In" RCA port of your stereo receiver or amplifier.
Shouldn't it be the Audio Out port on the Receiver if I'm using this as a headphones amplifier? Or, am I confused?

I currently run a Yamaha AG06 6-Channel Mixer USB Audio Interface in my studio, would this compliment that or be redundant? Thanks!

DEC + Preamp is an ideal combination, as you can use this mixer as a preamp to tune the audio.

Usually you connect an amplifier or receiver to a DAC. You wanna connect K5 Pro to a receiver? That will be uncommon as you try to connect a headphone amplifier to a receiver. Most receivers have built-in amp and line-out ports, unless the built-in amp is subpar. In such cases, why not connect the audio source directly to the K5 Pro instead?

This doesn't appear to have analog inputs. You would need to connect it to a digital source, i.e. USB, optical or coax. You could use analog outputs from this to your receiver if you think this has a better 2 channel dac than your receiver or if it has an input that you need (e.g. USB).

Separately, straight headphone amplifiers (not what this is) can take an analog (e.g. rca) line/pre source from your receiver or other dac and maybe make your headphones sound better or louder.

Thank you for your detailed response! I am currently plugging my headphones (Philips X2HR) directly into the phones jack on the front panel of the Receiver. It works fine but I feel the headphones aren't opening up quite as well as I think they could; hence, the idea of using a dedicated headphones amp. The reason I want the Receiver to be the source for the headphones amp is because all my devices--TV, PS5 and the SHIELD--are going through it. I'd like to be able to use the headphones with all of them.

Oh, thank you! You pointed out something I completely missed, that this unit has no RCA in. I should just stick with an AMP. Any thoughts on which one for my Philips X2HR (I'm also planning to get a pair of Senn HD600 sometime this year).

The price is good. I have been debating with myself if I should get one for the same price from TikTok as Audio Interface/Soundcard alternative.
Please share the tiktok link? I love tiktok and have got some amazing deals thru that app.

LOL. Marketed at gamers. Like there's a difference.

It measures terribly: https://www.audiosciencereview.co...iew.40047/

Like, it's broken, it's so bad. Embarrassing for Fosi.

Quote from nutriapeluda :
Im confused, how is this different than a headphone amp (other than price, quality, brand) like the monoprice ones that were on sale not too long ago?
Monoprice is likely much better than this broken DAC that has messed up frequency response. They added analog adjustment to a DAC and ended up with a broken product.
Quote from ddBqRvCpcFv6 :
How do I get clean out put from desktop pc to DAC?
USB, usually.
Quote from resseeker :
Is this good for something like the beyerdynamic 770 250 ohm? I've used them for a long time on a regular audio output, but wondering if this will make a noticeable difference in quality.

Redundant and probably much lower quality than your Yamaha.

This will mess up your frequency response. It's a broken DAC.

Some schitt products are terrible and some are quite excellent. Few are a value for the money. Look up measurements.

If you want to listen to music, there are many quality DAC choices out there. A good one will cost a bit more. If you want an all in one solution with quality dac, adc, and headphone amp, you're not going to find it for cheap, and it's sitll going to perform badly with a junky gaming headphone mic. If you're streaming, you should use separates and a proper ADC. If you're gaming, just plug into the headphone plug on the PC.

I picked this up for my Beyerdynamic MMX 300 headset (32 Ohms). I use it on my work computer and it's a great match. The Fosi seems well built and has plenty of volume if I switch to music while on break. I bought it specifically for the headphone and mic in jacks right on the front panel, within easy reach on my desk.
