If you have an expensive system, well that's awesome. The real question is what do you do with it? Does the music that you play uplift the spirit? Is it played at volume levels that others in the house are comfortable with? Do you get other family members involved by asking what they like and don't like? Do you put a playlist together and listen with your spouse to get a thumbs up or down on specific songs? Does the music also square with the deeper issues of Faith and Morality?
Like most things in life, it can be good or bad depending on how something is used.
