I have a digital receiver and would like to know whether I should get an analog or digital equilizer. I have no idea on what brand to get so any good brands or links is welcome. What is the major difference between analog and digital? Also, can the equalizer only be used on 1 piece of equipement (DVD) or can you connect multiple sources to it? If you can connect multiple sources to it, does it allow you save the settings for each source? I must admit that I don't know much about equalizers only that you can increase/decrease different frequencies to help balance the sound. Thanks in advance. Paul.
