The Magni 2 was my very first headphone amp and I did enjoy it for the most part. We have since parted ways, but overall it was a pretty solid piece of equipment.
I did a lot of research before making the decision to purchase one, and it lasted from December 2016 – December 2018 in my home studio.
Loads of research also indicated it to be a great pairing with the HD 600 which isn’t entirely untrue. In hindsight it probably wasn’t the greatest combo in the world, but it got the job done. I think that had more to do with the 3k issue apparent on the HD 600 and less to do with the clean neutrality that the Magni 2 provides. It’s a very crisp and detailed sound overall, and offers an accurate portrayal of whatever you’re listening through.
Thanks to it’s less than 0.2 output impedance, it will power 99% of headphones with relative ease as well. What is Output Impedance?
Here are some other Amps & DACs I have demoed/owned since venturing down the rabbit hole. 🙂
Solid build quality.
Works will nearly all headphones. There will be some exceptions, but for 99% of cans, you’ll be golden.
Easy to use. It comes with a power supply, and you hook it up to your PC via USB. All you need is the PYST RCA cables (or the Monoprice which I use and are a lot cheaper!), which hook from the back of your DAC to the back of the Magni. (I recommend pairing the Magni with theModi DAC).
Sound can be a bit grainy/unresolved vs. amps like the Atom and Objective 2.

Who this amp benefits?
Anyone needing a powerful Amp for their higher Impedance, lower Sensitivity headphones. The Sennheiser HD600 is 300 Ohms, and it powers them with ease. I only have to turn the knob to about 11 o’clock to get a loud enough sound.
How to set it up
You will need:
Magni headphone amp.
Modi DAC (or another digital to analog converter of some sort). I would just go with the Modi to keep it fresh. 🙂
The Sennheiser HD600’s, or another similar open back headphone that requires good amplification.
