I mostly listen to hard rock, but the best recorded band I have heard is Dire Straits.
Their mixing is top notch, and their music is filled with dynamic sounds that really demonstrate what imaging is all about.
My home system is still growing, but I have some goodies. Marantz SR7005 receiver, Oppo BDP83 universal player, a Marantz CD player that has been converted into a Hart tube CD player, through some Vandersteen 1c's and a Velodyne sub.
Upstairs, I also have a pair of Sennheiser headphones that I listen to with a Mark III headphone tube amp and a Rega turntable powered by an Anthem Amp.
