HI: Please keep in mind that the HP-100 is about three (3) to four (4) years old. There are several iterations in the pipeline even though all of them are "HP-100". The newer versions are much improved in the bass. I did not find the dymamics lacking. Personally I liked them. I have a unit that is about a year to a year and 1/2 old. I am planning to send it back for some changes that improve the bass. Mine is ok but it could be better in the bass. After the upgrade it will be the same unit reviewed by the Absolute Sound. They are quite resonable for their update cost. Any other company would have called it a Mark II and charge $600 more for the upgrade. As it is they only charge $140.00
Make sure you compare the Newer versions.
Good Luck
