I'm looking to finally get a decent pair of monitors. I have a feeling that the 8's will be overkill but I'm wondering if 5's will be sufficient or if I should step up to the 6's. My room measures about 13ft x 12ft. Also, what are a nice pair of isolation headphones to mix with? I was looking at the Direct Sound EX-29 since I've read great things about them and the price is great. Not to mention they have replacement parts for everything on them! I'm looking for something durable and pretty flat response. Price range doesn't really matter but nothing above mid-range. I'm going from nothing at all to something so I don't need anything fancy.
