I agree, it may or may not be something wrong. Kids do have their own schedules, and boys are generally slower. I don't think my son really babbled much until 11 months or so. We were concerned about hearing problems, but the doctor said to wait until 12 months and see, and by then he was making lots of noise and now he is right on track with words and speaking (he's 18 mo.)
However, I do think that mother's intuition is pretty good, so if you feel worried, it wouldn't hurt to take him to MCHC or your doctor and just ask for another opinion. They know that it's in the baby's best interest to catch any problems early, so don't worry about going in even if he ends up to be fine. Good luck!
