After having the SB-1000 for a full two weeks the unit is getting better and better. I re-calibrated several more times, changed speaker location several times and can clearly notice a performance improvement from the first few days. I am using the same MCAAC calibration system with all speakers set to the same settings but the SB-1000 has now “loosened” up and providing plenty of volume with the gain at 50% rather than having to be 75-85%. It can now shake the floor without difficulty while maintaining the sharp, clear and precise deep notes.
Not being the professional reviewer I can’t write with all the jargon but I can say it is doing one heck of a job.
