I had the Q Acoustics 3020 and the Infinity Reference R152 on hand to do a comparison, given the original MSRP of all 3 speakers were around the same, $300-350.
The TP160S, although no bass monster, has better impact than both the 3020 and R152. It sounds like a bigger speaker than the 3020 (which it is),with a fuller, more well rounded sound (and it sounds a little bigger than the R152 as well) It also disappears better than the 3020. Both the TP160S and the 3020 are a touch forward which makes sound more "exciting" at times, but the TP160S never became too shouty/annoying. Tonality is pretty balanced, similar to the Infinity's. The R152 does have a little cleaner sounding highs with more depth and separation in the soundstage with more distinct imaging, but it would've been tougher to notice if I wasn't able to compare them back to back.
