Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- Unison Research products are hand-crafted in Italy, using locally sourced materials and distinctive design elements like wood trim and stainless steel, creating a unique visual aesthetic.
- They specialize in hybrid amplifier designs, using tubes in the preamp stage and solid-state MOSFETs in the output stage, aiming to capture the sonic benefits of both technologies.
- They custom-design and manufacture their own transformers, tailoring them to specific amplifier models for optimal performance and a unique sonic signature.
- Unison Research designs incorporate minimal stages and often utilize zero feedback, prioritizing sonic purity and a balanced sound across a wide range of music genres.

Our take on the brand
Look inside the brand
Our interview with the brand
What are two key technological innovations or strong opinions that differ you from other brands?
We’re an Italian company that sources everything as locally as possible. Italian through and through—everything we do is done here in Italy. Italian gear really does have its own sound. Sounds more romantic, less analytical. Very listenable. Low levels of ear fatigue.
We’re still hand making tube amps and continually refining them. New innovations in grounding, such as each component being grounded independently so they're really quiet as far as tube amps go, is an ongoing focus—always evolving mature tech.
But we also have new modern tech that's a hybrid of solid state and tube—to give you the best of both worlds. You can run pretty much any speaker you want.
In short, it’s a really easy to listen to sound.
What's your approach to customer support?
What are your favorite tracks for showcasing the strength of your products?
What other products pair best with yours?
Opera speakers are a great pairing because they're under the same parent company . When Unison is voicing their amps, they use Opera speakers, and vice versa.
However we've had no issues with pairing with Unison research. (But if you're looking at tube gear, you do have to be more careful because you do need a more sensitive speaker.)
In fact, are your speakers very technical? Pairing with Unison Research can help tame that a bit.

Product Strengths
- Each detail of the Signature has been carefully crafted and sees numerous updates over the standard 801, including crossover upgrades and a modified cabinet with a refined downward firing port
- The bass presentation on the 801 Signature was better across the board, it was tighter, a little more pronounced and forward, and definitely more defined
- Bass goes beyond just hitting the low notes, the woofers showcase some of the clearest, most audible detail and texture
- Vocalists and actors have better inflection, greater scale, and detail playing at low volumes
- When properly set up, the Signature is one of the most holographic windows to music experienced
- Speakers need power, the Arcam was impressive and even got the 801s to play loud, but the Macintosh MC312 made the Signature sound flow-like water
Product Considerations
- The Signature's impedance fluctuates wildly, ranging from a nominal 8 ohms and dipping lower than 3, so you need an amplifier that does more than just work
- Placement matters: if placed too close to the wall, the bass response became too pronounced and even boomy at times
- The Signature can come off as bright, and in extreme cases, it might be fatiguing to some
- Poor recordings won't get a free pass, there's bound to be a track or two that's going to leave your playlist rotation
Comparisons (according to reviewers)
- Compared to the Klipsch La Scala, both speakers excel at the recreation of space in true-to-life dynamics
- Compared to the Wharfedale Elysian 4, the Elysian doesn't play as deep, is richer in the mid-range, and nowhere near as extended up top, so it's not the Signature's equal
- Compared to the Wilson Audio Want Puppy, the two speakers are similar in size, driver complement, build and finish quality, price, and target market
- Compared to the SVS Titan, the Titans sound two-dimensional and fat, compared to the Signature's far more realistic and natural-sounding bass
- Compared to the KEF R11 Meta, the Signature's beefy presence makes for a far grander statement
Takeaway: The 801 Signature is a speaker that elevates the listening experience to another level because it is designed with incredible attention to detail. It will be an emotional and immersive experience to own these speakers.

Our take on the brand
Form Follows FunctionV-Material is nested in the top of the woofer and midrange enclosures for increased vibration mitigation and control. By using X-Material throughout all three modules, and methodically refining the internal bracing and panel thicknesses, Wilson Audio's Engineers have enhanced enclosure damping to a new standard for this product category.
Product Strengths
- Alexia V brings many of the qualities of the Chronosonic XVX to a smaller and more affordable loudspeaker
- Spectacular bass performance delivers powerful weight and muscularity without sounding thick or overblown
- Midrange shares harmonic beauty and warmth with the XVX, offering smoothness and ease
- The Alexia V presents real life to the listener in a way that previous versions cannot match
- Every detail of the design and build exudes the highest level of quality and craftsmanship
Product Considerations
- Premium-priced, putting it out of reach for many music lovers
- Alexia V sounds a bit more forward, incisive, and "extraverted" compared to the XVX
Comparisons (according to reviewers)
- Alexia V shares many sonic characteristics with the Chronosonic XVX, but sounds a bit more forward, incisive, and 'extraverted', the XVX is more subtle, refined, darker in tonal balance, and 'bigger' sounding
- Alexia V is unequivocally superior to the Series 2 in every way
Takeaway: The Alexia V brings many of the best qualities from Wilson Audio's top-of-the-line speakers into a more manageable size and price point. The sound is both powerful and refined, making listening to music an engaging experience.
