For earphones, choose from two super low gain options, to provide a wide volume range and clear, noise free background.

Powerhouse !

I've only had it a week now, but it's been a great week. Had to update USB driver and make some settings in Tidal to set up MQA. Great support from ifi. After, this the beautiful piece of kit worked flawlessly. The buttons can too easily be removed accidentally. Good thing there are extras in the box. This the box includes everything you'd need, even an audiophile grade OTG to hook up to your cell or tablet. Or a computer with C USB. It was a great unboxing xp. I'm using it to drive my Focal Elears and the ifi does it flawlessly with lots of power to spare. I love the sound. Tons of dynamic headroom to scare you once in a while. Be careful not to overload your cans. Would be easy. Start out in lower power mode. The volume knob is very sensitive. I like the XBass and 3D for low level listening. Careful with XBass at higher volumes. Turn down the volume before flipping the switch. I find there is lots of soundstage. The unit is an attractive and well built unit. I haven't yet fatigued of the listening to it. The sound is on the warmer side, and you can brighten the sound with the 3D. There are 7 switches to dial in your setup. Great for any kind of can or IEMs. I've tried the RCAs output to my fairly new amp. Sounds great. Sorry to say I haven't been able to get the COAX in/out to work yet. I haven't tried the optical input yet. I hope it works. I find the iDSD sounds best on my Samsung cell phone. I have a powerhouse ROG laptop that emits huge amounts of noise and interference. So I've tried it on those 2 sources. The asking price for this unit is very fair considering all that it does and all that is included. It's easy to use but be careful not to bump switches or loose the nobs. It sounds well above its price point. You'll get a lot for your money. Headphone Bar has been excellent. I like doing business with the store. They answer emails quickly. They ship quickly. Great communications and service. Like making sure I have the cables needed. That's service. Thnx!

Great flexible portable DAC amp!

I'm using that mostly for work and it does a great job. Feeds any headphone without effort (I tried 13 to 300 ohms). I often use the Xbass and 3D options, those are well implemented.
