Can't say, I haven't heard the magni. The DF gets better with the Jitterbug, if you want a cheap upgrade you could order one. Even the DF Red is said do be better with the Jitterbug. The DF Red might also be a good upgrade. It probably comes down to how much you are willing to invest, the DF Red...

Do you really need the Magni? I have the Amiron Home and use them with a DragonFly black without anything else and get enough volume. I also have a small Ifi and if you want to go one step up the Ifi Nano iDSD Black Label seems to be popular. If you can afford it the Ifi Micro iDSD Black Label...

Just another tip, the Beyerdyanamic Amiron Home is said to be very close in audio quality and about the same price. Somewhat "easier" to listen to but still very revealing and very, very good.

You can also get new headphones. The Amiron Home is said to be very similar to the dt1990 but more relaxed, softer.

I like both the Classic Line and the give-away. I would like a micro iDAC2. I actually have a nano iDSD LE but would like to hear something even better.
