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.

The dogma of separates has long reigned supreme among audiophiles: If you're serious about sound quality, you're supposed to need a dedicated preamp and power amp. The logic goes that separates reduce interference and offer maximum control over your sound. But there's an argument to be made that integrated amplifiers are more practical ... and potentially better-sounding.

The beauty of an integrated amp lies in its synergy. Audio engineers know exactly how the pre and power sections will interact; the two are literally designed to work together. On paper at least, that means optimized impedance matching, and signal integrity that can rival and perhaps surpass separates. How do you know whether a standalone preamp is a great match for a power amp? For most of us, it's through trial and error. It isn't unusual for restless stereo aficionados to own multiple combos over the years, in search of the ideal one. That gets costly.

Then there's the fact that an integrated amp helps declutter a room, appealing to minimalists and people whose living spaces are less than cavernous. Another plus: no need to shell out for audiophile-grade interconnects.
