+1 regarding Music Lovers. Good selection, and incredibly helpful staff in my experience, anyway.
Be weary of Audio Vision. They literally charge you $250 if you want to audition any gear and you are only given that money back as a credit if you make a purchase within 90 days. Also, in my three or four times of walking in, each time was greeted with serious attitude.
They do offer a huge lineup of gear though, so if you know what you want and don’t want to deal with the trouble of going through an LA dealer, they might be a worthwhile option.
