I must have the meantime, well-known history of AC / DC and I want to mention anything more at this point. AC / DC, the power-veteran, with its intersecting Gibson SG Sound is not only a feast for the ears for the lovers of the "real-Rocks" (sodenn there are good ...), but also test example of good hi-fi tower speaker. Played through the Kappa 8.2.i is a monumental soundscapes with this CD to light. An absolute best buy for the Rock Freak !!! Thunderstruck example for me is the hammer on this CD, all other are added to really live Super Quality. A killer horny CD is second to none ...
