Budget Component Reviews

In my review of Polk Audio's RT25i loudspeaker (September 2001, Vol.24 No.9), I was mightily impressed with Matthew Polk's execution of this $320/pair design. Although it has since been replaced by the RT27i, with slightly modified cosmetics and a different tweeter, the RT25i remains my favorite loudspeaker costing less than $500/pair.

I first met NHT co-founder Ken Kantor in 1975 when we were both undergraduates at MIT. Kantor was sponsoring an extracurricular class entitled "Musical Ideas." The concept was to stick a dozen or so musicians in a classroom for free improvisation and hope to create music à la Miles Davis' Bitches Brew. The result was a mess; although talented guitarist Kantor meant well, there was no common vision or consistency of musical talent. Nevertheless, I had a blast trying to simulate a tamboura drone with a Hohner Clavinet, phase shifter, and volume pedal.

I have always had an affection for speakers designed and manufactured by the Canadian conglomerate Audio Products International Corp. (API), which markets speaker designs under the names Mirage, Energy, Sound Dynamics, and Athena. In fact, it was 20 years ago that API created the first budget speaker that caught my attention, the Mirage 350. At the time, the 350 was the only speaker I'd heard that cost less than $300/pair. It sounded open, musical, and detailed without seeming bass-shy. (A larger successor, the 460, was for many years my reference home-theater speaker.) Although I've been impressed with many other API designs I've heard over the years at friends' houses, press events, and hi-fi shows, it had been more than a decade since I'd formally reviewed an API product.

Paul Barton is a legend in the speaker business. For 25 years this musician and engineer has dedicated his life to providing speaker purchasers with higher levels of sonic realism at lower prices. Barton is a frugal perfectionist, and his obsession with psychoacoustics is evident in all his designs. I was mightily impressed with his midpriced Image 4T (Stereophile, February 2001), which was, like all Barton designs, designed with the assistance of the facilities of Canada's National Research Council.

I haven't been shy in these pages regarding my love for the Mission 731i loudspeaker (reviewed in November 1996, Vol.19 No.11). It quickly became my reference standard for an entry-level audiophile speaker. Subsequent to my review, Mission significantly improved the speaker by introducing a silk-dome tweeter (see Follow-Up in April 1998, Vol.12 No.4). I bought three pairs: one for my home recording studio, one for my faux outdoor summer-home system (guest bedroom windowsills, pointing outward), and one for portable use to drag to friends' parties when their sound systems are not up to snuff.

NAD has been out there on the leading edge of entry-level high-end sound long enough that some audiophiles reckon they invented the category. Sure, we should give serious props to the likes of Creek, Rotel, Musical Fidelity, Arcam, Denon, and Parasound, all of which have made significant contributions to the musical aspirations of budget-conscious pilgrims. But I continue to harbor warm feelings about my last extended visit with an NAD component: the inexpensive yet supremely musical L40 CD Receiver, which I reviewed in the June 2000 Stereophile.

Sony describes the $700 TA-P9000ES as "a pure audio multichannel preamplifier equipped with two inputs for 5.1 analog multichannel audio sources, enabling selection, volume control, and amplification." A relay with twin gold-plated crossbars switches the two six-channel sources. Then follows a class-A solid-state push-pull amplifier in discrete configuration. Separate transistors, resistors, and capacitors populate the printed circuit boards. An oxygen-free copper shield surrounds each channel to prevent crosstalk between the channels. In addition, there is a relay-controlled gain stage offering 0, +6, and +12dB amplification.
