When I reviewed Infinity's Primus 150 loudspeaker in the April 2004 Stereophile, I was very impressed with its overall performance. To this day, I continue to be amazed at the level of realism this $198/pair loudspeaker can reproduce, and I've kept the review pair to serve as a benchmark for an entry-level audiophile speaker. When I'd completed that review, my first thought was: Now—what can Infinity do within the affordable Primus series for more money? So I requested a review sample of the Primus series' flagship, the three-way Primus 360 floorstanding speaker. After all, how could I resist listening to a speaker that claims 38Hz bass extension for only $658/pair?

I have always been a dyed-in-the-wool vinyl fan, committed to the superiority of analog over current 44kHz/16-bit CD technology. Nevertheless, I have been surprised at how greatly the sound of CD has improved over the past 10 years. By 1994, digital had gotten much closer to analog than I had ever expected, which was a good thing, as 1994 also saw the disappearance of the LP as a medium for obtaining new releases of mainstream recordings. But over the last two years, I've noticed some interesting phenomena: More turntables, tonearms, and cartridges started to become available, at least in the high-end arena. Audiophiles and, to a lesser extent, segments of the general music-loving public, began clamoring for new vinyl releases. Specialty labels, such as Classic Records and Acoustic Sounds, started to reissue premium vinyl releases of classical, jazz, and pop classics at reasonable prices. And major labels again began to offer vinyl versions of major pop releases.

Paul Barton, founder of PSB Speakers International, is an icon of the North American speaker industry. A talented designer who has for many years produced innovative and cost-effective designs at a range of prices, Barton does not let time stand still, constantly updating and revising his designs. But what makes him unique, in my view, is that, unlike the designers at most North American speaker companies, whose successful affordable designs are trickled down from their more expensive models, Barton, like the British designers, seems to get most of his excitement from his budget lines. His original PSB Alpha was, in its day, the most significant entry-level speaker made in North America since the original Advents of the 1970s.

In the September 2001 Stereophile (Vol.24 No.9), I wrote very favorably about Polk's RT25i loudspeaker ($319.90/pair). That bookshelf model impressed me with its open, neutral midrange; its pristine, extended high-frequency response; and its low-level dynamics. On the minus side, the RT25i was fairly limited in low-bass extension and high-level dynamic slam. At the time, I was seeking a new speaker for my home computer music-composition system, and I bought the review samples—the only time I've done that since I began to write for Stereophile some 20 speaker reviews ago.
