My SongTowers are on order. Although I took a 10 year hiatus from audio (no, I wasn't in prison; my kids were small and liked to demolish things), over the past thirty five years, I have had numerous speakers, perhaps even more than some dealers, since my father was in the audio service business. The SongTowers will replace my every day speakers, a pair of Spendor S3/5, that are the backup speakers for my KEF 101 Reference Series, which I don't play very often. I have a small room and listen close to nearfield, and the Spendors are O.K., although not as crystal clear as the KEF. I was fairly happy with the Spendors until I bought my new AVA gear, and then the Spendors' limitations became more apparent (and the attributes of the KEF 101, in comparison to the Spendors, became more apparent, too).
I've been pouring over the Salk reviews, and initially intended to purchase the HT-3, but the SongTower will arguably be easier to configure in my small listening room. Obviously, I can't yet compare the Spendor and the SongTowers, although I expect the SongTowers to have a deeper, well-defined low end. I am not a fan of booming, sloopy bass, where the instruments or notes are indistinguishable and every low note sounds like a thump, and I have previously avoided changing speakers or adding subwoofers. However, the reviews of the SongTower praise it's bass response, and I am expecting great sound, all around.
