After asking so many questions on HTF I've decided to actually contribute some content. It seems like a pretty common question here on HTF is if the Titans are worth the extra money over the Atoms. Since I own both models I decided to do a little comparison. First a disclaimer: I’m not an audiophile. Up until about a year ago I thought a giga-tube mini-system was hi-fi! I am using mostly low-fi stuff but did my best to ensure consistency in testing. The equipment used was the following: Paradigm Atoms v3 Paradigm Titans v2 My DIY stands SBB4 Tempest Subwoofer crossed over at 100hz Pioneer VSX-D510 RCA 5240P DVD player(probably the weak link of the system) Speakers were connected using 16 gauge Radio Shack speaker wire The receiver was set to source direct mode for testing. The speakers were placed in a triangle in which the distance between them was roughly ¾ the length of the distance to my listening position, which is recommended in the Paradigm manual. They were about 16 inches from the wall. Both models were tested in the exact same spot toed in on stands that put the tweeter almost exactly at ear height. So anyway, here is what I found: Movies: In HT use there was almost no discernible difference. In fact I honestly couldn’t tell a difference except at loud levels. At near reference levels the Titans just seemed slightly cleaner. Music: Now, in music some differences did become more apparent. I tested with and without the subwoofer. Without the subwoofer there was no comparison. The Titans were considerably better. The larger enclosure and mid-woofer allow for considerably better bass quality and extension. The Titans certainly sound much larger than the Atoms. The bass from the Titans was actually adequate for many types of music without a sub. The Atoms weren’t poor by any means. They sounded very clear but they had no authority in the bass department. With the subwoofer the two became harder to differentiate but there were still some differences. At low volumes there was little to no difference. At louder levels some differences were noticed though. Like in HT use, the Titans sounded less strained at loud levels. The other thing I noticed is a little harder to explain: At loud levels, it seemed that with the Atoms it was more noticeable that a sub was being used. I think this is because the Titans can hit the notes below the crossover with more authority thereby fooling your ears into thinking it is the source of deep bass. My conclusion: The Atoms are very good when used only for HT and when space is small. However, the extra money invested in Titans is well worth it, in my opinion. If you aren’t using a sub, the decision is easy, just get the Titans. My only concern about my testing is the v2 vs v3 issue. I'm not sure if this would have a significant effect. Any comments?
