For me... in my system... I'll take the Magic IIs over the AZs... any day.
That said, the HT Magic IIs ain't the end of the road either.
I've had both at one time or another in my rig (s). I use the HT M II as the main IC. it has decent bass, not the last word there, good tone, nice detail, and resonable resolution, while not bleaching out the color of the music.
I refer to the Magic II casually as the 'poor mans' MIT magnum. though they are quite different in some areas they are more alike than different... namely the color aspect.
Let me put it another way, I could easily go with the Magic IIs thoughout, but not the Magnums throughout, I don't think. They are too intensely revealing and reduce the vibrancy of the musical tones.
The HT Magic IIs are a better cable too than the older Is, yet both are worthwhile considerations as ICs. I found the IIs overall a better solution for me than the AZ cables for the IIs conveyed more of the venue ambience, and allowed for great detail without being strident or too 'hi fi-ish' sounding. Tjhey work well just about where ever. I loaned out my own set to a friend who has the older Is and together he felt his system got a significant shot in the arm and was well pleased with them, until he had to send them back to me. Like the Cardass neutral ref cables, I think everbody should have a set of each issued to them when they get serious about building a system as a baseline ref or last step. Depending on the means, of course.
Magic IIs work well also with tubes or SS. the price tag on the AZ & HT says it all IMHO.
