I believe that are are a few other cosmetic changes as well. The ES of 2014 would be ES1.3 while the 2006 would be ES1.2. You also have the option to order the 2014 with or without the cutaway, and with or without ES. There may be other upgrades available on the 2014. You may want to check the pricelist on Taylor's website for more details. Otherwise, woods and bracing should be the same between both model years.
