Since the original WATT/Puppy concept kicked off in the late 1980s, there has been a 40-year evolution leading to the latest version reviewed here. The loudspeaker's price in 2025 is around $40,000/pair compared to the original's $8000. While inflation alone would have lifted the price to $25,000/pair, the current price takes into account the many technological and design improvements. While remaining physically separable, the upper "WATT" (Wilson Audio Tiny Tot) component, namely the head unit of the latest design, can no longer be run as a small full-range loudspeaker in its own right. This is because the mid/treble crossover, which was originally in the WATT, is now relocated to the lower "Puppy" section. Certainly, that original two-box "full range," strongly sculpted WATT/Puppy stack radically broke the mold in deviating from those rather plain, coffin-shaped tower loudspeakers that were popular in this category.

The late David Wilson originally created the WATT as a shelf-mount studio monitor to help produce his recordings. At the time, this compact two-way promised near–state-of-the-art sound quality, especially transparency, indicative of very low self-noise. This quality also helped to maximize dynamic range and contrast. Later, David used the WATT as the foundation for a three-way floorstanding design by matching it to a low-frequency system (the Puppy), which also stood in as a physical platform for the WATT. This idea became reality in the successful W/P line of bass augmented systems.

An ancient connection: Monitor Audio began in 1972 when John Bartlett, founder of the innovative retail chain Audio T, introduced me to Mike Beeny, manager of an Audio T branch near Cambridge, and Mo Iqbal, a local electronics wizard. Mike suggested that Mo and I join him to start a loudspeaker company. Monitor was a fashionable hi-fi term, and I suggested we name it Monitor Audio Ltd. Each director put £300 into the company account. It was registered as a PLC at an address in Teversham, Cambridgeshire. We rented an upper floor office in a warehouse close to Mo's home, since Mo worked all hours. There was additional workspace in his huge double garage. Mike directed sales, Mo was responsible for production management and accounts, and I took the position of technical director for research and development. I also helped supervise production. Lorna Parker was our office secretary.

After launching a handful of increasingly viable designs, we reached a then-astonishing turnover of £1 million in our first year and enjoyed a very successful showing at the Paris Festival du Son. But by this point, I was close to an overwork-related breakdown and reluctantly resigned.

As founder and chief designer of Sonus Faber, Franco Serblin designed and manufactured many loudspeakers of acclaimed high quality, mainly in box form. Nevertheless, he remained painfully aware that such conventional rectangular parallelepiped constructions inevitably possessed an inherent and hard-to-suppress resonant signature characteristic of box-form cabinetry, significantly differing from that for a musical instrument. Franco had long obsessed over the sound and construction of classical string instruments, violins, violas, and cellos made by grand masters over centuries. He valued highly those richly resonant, expressive, complex sonic signatures.

Based in Bulgaria, European audio company Thrax has been active since 2009. Their ingenious and varied design approaches seen over several product lines have continued to intrigue me with their conceptual originality, innate musicality, and imaginative use of a broad spectrum of technologies. Their products range from valve (tube) amplification to digital audio and, more recently, loudspeakers . . . The range of distinctive high-end electronics has continued to expand to include a loudspeaker, the standmount Lyra, now joined by the smaller Siren ($13,600/pair), also a standmount and the subject of this Stereophile review.

Naim has comprehensively reimagined its Classic Series, which has been around for some 20 years with improvements along the way. Included in the new range of products is the 200 series, comprised of two products: the NAP 250 power amplifier, which I reviewed in the November 2023 issue of Stereophile, and the NSC 222 streaming preamplifier ($8999), which is reviewed here. A third component in the New Classic series, the NPX 300 power supply (also $8999), which is intended to be paired with the NSC 222 and other Naim components, is also considered in this review.

For this modular audio component set—a review of the matching NSC 222 streamer preamp with a matching NPX 300 power supply is forthcoming—we first cover the standalone NAP 250 100Wpc stereo power amplifier, a new version of Naim's 200-series amplifier, now so extensively revised that it must be regarded as a new model.

Naim Audio's enduring, compact 200-series stereo power amplifier has been relaunched as the NAP 250, a key component of their new 200 Series. It has been updated massively in its technology and the compatibility of its connections, yet the primary circuit concept, which dates to the mid-1970s, is essentially unchanged. Recent development work has focused on helping the amplifier match up well with the new NSC 222 streamer-preamp, the NAP 250's intended companion. The new 200-series power amplifier is now called, simply, NAP 250, dropping the "DR" of the previous model. But while the suffix is now omitted, the ultralow-noise DR technology has been retained in the active, fully regulated power supplies; indeed, it has been improved.

With the furor over the launch of DAT (digital audio tape), it is worth remembering that commercial digital recorders have been with us for some time now: it is now nearly a decade since studio PCM converters were first successfully used for audio recording in conjunction with a VCR (which uses a helical spiral recording via a spinning drum to achieve the high writing speed).

Few designers are drawn to create horn loudspeakers. Most people's experience of horns is based on the resonating, overdriven, often overloaded PA installations heard at rock concerts and similar events. These commonly heard unmusical noises and colorations are ever-present in designers' minds. But good-sounding horns do exist; over the years, some noteworthy commercial examples have appeared, though few have been full-range.

Landmarks in speaker design have been few and far between. There are a few certain contenders: in the UK, the original Quad Electrostatic and the ESL-63 qualify, while the Celestion SL600 scored a big point for all small monitors; the Spendor BC1 changed forever the notion that cone speakers were always colored and that big boxes were essential for good sound. In the States, Apogee has taught us much with their surprising mid-treble ribbon-based designs. Other technologies have shown promise but have not achieved real commercial success.

Exposure owner/designer John Farlowe graduated from the UK's University of Sussex at the end of the swinging '60s. He put his B.Sc in electronic engineering to use at HiWatt, manufacturers of tube guitar amplifiers. His keen interest in pro audio, particularly in sound reinforcement for rock bands, led him to Midas (studio mixing desks and systems), where, as director and designer, he designed and built mixing desks and got together with the late Dave Martin of Martin Audio. They became heavily involved in sound systems for Pink Floyd. Midas desks and Martin speakers were used at many live venues, including those at London's Rainbow.
