Our take on the brand
Our Summary
Product Strengths
- Sublime image size and expansiveness, coupled with an ability to be driven as hard as your ears or your amps can take
- A sense of balance to the sound of the Alexx V makes renewal possible, expressive and articulate from the deepest bass to the highest treble
- Trickle-down benefits from the WAMM Master Chronosonic and Chronosonic XVX
- Bass performance is otherworldly
- The Alexx V has the ability to uncover and continue to deliver micro-details at extremely high SPLs, even after that slam of a transient
Product Considerations
- Some power behind the throne is needed, because the loudspeaker's impedance plot drops to two ohms at 250Hz
- The dome tweeter does sacrifice the last ounce of micro-detail, compared to the insane resolving power of the best diamond and beryllium drivers
- The choice of finish needs to be considered with care
- Cable management can impact performance
Comparisons (according to reviewers)
- Compared to the original Alexx, the Alexx V is a massive improvement—closer to a baby XVX in so many ways
- Compared to the Alexia 2, the Alexx V was more than a mere additive sum, a step-function improvement
- Compared to the Wilson XVX and WAMM Master Chronosonic, the tweeter is effortless and resolving by normal standards, but no match for the extraordinary levels of detail retrieval
Takeaway: The Alexx V offers a sublime listening experience with excellent balance and dynamic range that allows the listener to get closer to the music. It is a worthy contender for those looking to upgrade their listening experience.
