Theses speakers are kick ass. I use the Triton 1's in a 2 channel no thrills set up, powered by a XPA-2, XSP-1, OPPO 105, and pro-ject turn table. My room is about 18 feet by 25 feet. I had the Triton 2 in the exact same set-up and just swapped out the speakers and took turns listen to each with the same tracks and same volume with a mixture of flacs, cd's, and vinyl. The 1's sounds magnificent, the overall sound is noticeable different, mostly in the bass and mids. At the same volume, the speakers fill the room with music better, I am not sure how much is due to the speaker itself being larger and dispersing the sound in the room better and how much is really due to the better low and mid performance. The bass does it though, although the Triton 2 were no slackers in this department, the 1's for two channel music are something else, you don't miss a sub at all. Given the size of my room, the Triton 1 are more then I need and I am not sure how many would really benefit to getting the 1's over the 2 unless you have a large room or home theater, thinking about it objectively. Don't get me wrong I would buy them again in a heart beat. My only minor issue/complaint is that the bass is too strong depending on what you listen to, and it should be dialed back a little (closer to ten and a half), with the Triton 2 I liked them closer to 12. A lot of you guys will run lapse around me with your technical and practical audio knowledge but these are just my thoughts.
