Fosi Audio - K7 DAC Headphone Amp for Gaming - Black

I have needed a DAC for a while now, and Fosi has been on the list of potential options. Fosi put out an ad saying that they were now selling products at Best Buy, so I decided to grab this and the C3 from them. The K7 is a good entry point if you want a mix between a gaming-focused DAC and something for an audiophile. Mine is hooked up to my computer via USB and to my CD player via an optical connection. It has a dedicated mic 3.5mm port, a headphone/IEM 3.5 mm port, and a 4.4 mm port on the front. It has a simple Bass/Treble adjustable EQ preset that can be bypassed (I find this feature exceptionally useful as I test alot of audio gear). I don't use the Bluetooth feature or any of the other inputs/outputs at this moment, but as my audio gear collection grows, I will find use for the additional connection types. It came with a USB-C to USB-C cable that has a USB-C to USB-A adapter attached to it. It also has a 3.5 mm to split mic and headphone connection in case you are using a headphone/IEM with an inline cable microphone. It does display the input data it receives from its source, so it did clue me in when I was streaming music at a lower quality than it was capable of decoding. There are 62 steps on the volume control, which I find to be a bit lackluster. I would like a 100 or more so that I can more finely tune the volume of it. At times, with the Dunu Mortise, I found myself adjusting volume between songs because one song would be too loud and then the next too quiet. Fosi provides some "preset" Bass/Treble EQ settings (Bass -2, Treble +2 as an example) for different games, but I find this to be unnecessary. EQing based on a game and not the listening device won't give you the best audio for that game unless you are using something like studio headphones that have a flat frequency response curve. Most consumer audio gear does not have a flat frequency response curve. I will say these EQs are a good starting point, though, and tweaking them slightly will help. Final notes. There is no audible noise floor on my unit, even with a 16 Ohm IEM. The buttons and dials do have a very nice tactile feel. It takes up a fair amount of desk space, so if you don't have a ton of room, I would look at the C3 instead. It has the option for UAC 1.0 and 2.0, so it can hook up to consoles like the Switch and PlayStation 4/5 (I did hook up my Switch to it, and it works). This is an easy recommendation for me to give, and I have really enjoyed using it for audio gear reviews.
