I'll disagree with Raven on this one. I hear a good bit of difference going from the magni to the A2. In simple terms the magni has a harsh leading edge to upper range that I didn't like. While the A2 is also a clean mostly neutral amp, there is no harshness and there is wonderful rendering of music that never sounds strained...just refined, effortless. There is linage borrowed from the mojo for the A2 for sure.
Forgive me if this has been discussed earlier in the thread, but do the he 400s really require the recommended 150 hours of burnin. It seems excessive to me, does the sound change much?
My he 400s arrived earlier today, but THE CABLE WAS DEFECTIVE. the right connector of the cable was broken, so I will have to wait till it gets replaced to finally listen to them, it's hurting me having them next to me but not being able to listen to them.
It's shameful IMO that after all this time, all the cable problems with the he400...that HFM continues to ship them. The cable on the he4 was brilliant. For shame...
