I would never judge the sound/tone of a guitar based on what I hear on YouTube. There are too many variables: your speakers, your listening environment, the mic it was recorded with, the room it was recorded in, the sound card on you computer, etc., etc., etc. You can get a vague idea of how one sounds against another - recorded in the same environment, under the same conditions, but the sound you hear over the internet can't be used to accurately judge the sound of the guitar.
But with that said, from everything I have heard about Taylor guitars (I own an 814), they are very consistent due to the mass production/manufacturing process. Every guitar in the same series will have a similar, but different sound quality. They will all have the "Taylor sound." And the build quality (fit and finish) is second to none.
My 2 cents...
