I currently own both the 107.2's and 105.3's and much prefer the 105.3's. The 105.3's have newer technology drivers, tweeters, and crossovers. They are 4 way and have a lot more detail in the highs, mids, and midbass with a punchier low end. The 107.2's use the old T-33 tweeters which sound harsh and edgy in comparison. Also the 107.2's lack mid bass since it only has 1 5 1/4 mid driver compared to 3 6 1/2" mid drivers of the 105.3's. Imageing is good on 107.2s but better on 105.3's. 107.2's have lower low end but is rather loose and bloomy. I am only keeping my 107.2's for nostalgia sakes and since they look nice, I don't listen to them. If you want to stay with Kef, I'd go with 105.3's or a pair of Model 3's or above.
