I am very fond of Totem's. Fell in love w/ some Model 1's several years back. Last year I picked up a pair of Arros, along with Lightening sub and DreamCatcher center and surrounds for HT use.
As noted previously in this thread, I found that the different speakers in the Totem line have somewhat different personalities. At least to my ears, there is just something special about the Arros. Their slim size and ease of placement (especially for HT) was just a bonus for me. I listen to mostly jazz/classical/instrument/vocal, and the Arros work well for this stuff.
BTW, I've been very pleased with the Arro+Lightening combination.
Let us know how you like your new speakers! People love to debate about "break in" issues. All I can say is that my Arros absolutely benefitted from the recommended break in time.
