I was wondering if anyone wanted to be rid of a Magni. They're pretty scarce on the FS forums.
Just got the Magni today. It seems to be pretty decent (good amount of power), but...when there's no music playing, it's like aliens have invaded. There's this weird quiet frequency sweepy sound coming through them, like a radio or walkie talkie station not dialed in correctly. Has anybody had this happen to them? I had somewhat similar issues with the Asgard I bought a while ago (returned it partially due to the noise and partially due to heat).
It might be where the USB is plugged in, I know that on my laptop I don't have that problem, but on my desktop i have the same issue. That or it might be also where the amp is plugged in, I'm thinking of picking up some ferrite beads/core to see if they work like some have said in the thread.
Try using better shielded cables (cheap ones!) or attach a Ferrite bead from radioshack to the power cable.
My Magni was noisy for awhile too.
hi - maybe - by the way - this happens exactly at the same position of the tune with my AKG K271 s - (55 ohm)... but again not with the 32 ohms
The break in period is about 1 nanosecond, or, the first time you turn it on and hit 'play'.
Your personal break-in period is probably a few hours, to a few days or weeks depending.
Not sure if it was the Magni or Modi (as I got and tried them as a pair), but I noticed a large change after a couple hours. I actually immediately listened to them out of the box and thought they were rather shrill. So I left them playing for an hour or two while I went to watch Doctor Who then came back and listened again.
I couldn't say how long the change took, it might have very well been after 10 minutes, but it was at most a couple hours. Beyond that they sounded similar enough that I couldn't say with any confidence that they changed any further in the next few weeks until I sold them.
