Hi, your off to a good start.
Few things that might be worth a look at.
Your pages are off center, seems like your building the site as it looks on your BV screen & should have started from the far left of the BV page. You have this also set up at 1200 wide & would save the side scrolling if it was just under 1000px wide.
Quite a few of the images need optimizing to get the pages loading faster, IE:
http://www.bostonaudiodesignonline.com/2.html took about 50secs to fully load.
But like the colors & style.
Good luck.
