The Bryston 3B Cubed: A Modern Legend with Studio Soul

In 1973, a prototype amplifier, the PRO 3, earned its place in a top recording studio on its very first audition. That legendary DNA, refined over nearly five decades of relentless engineering, lives on in the Bryston 3B Cubed. It’s an amplifier with a direct lineage to the professional world, built to deliver breathtaking realism and unflinching reliability in your home.

The Power of Purity, Distilled While it traces its heritage back to the studio, the 3B Cubed is a thoroughly modern powerhouse. It incorporates the same exclusive, patented technologies—like the remarkable Salomie circuit—found in Bryston's most venerated Cubed Series amplifiers. It shares the same sonic heart as its famous bigger brother, the 4B, offering that same level of transparency, detail, and control in a more compact and versatile form factor.

At its core is a true dual-mono design, with fully independent power supplies and transformers for each channel. This uncompromising architecture delivers a vast, stable, three-dimensional soundstage and unlocks a powerful 200 watts per channel (up to 300 into 4 ohms). This is power with purpose: an iron-fisted grip that commands your speakers, revealing effortless dynamics and subtle nuances in every recording.

 

Intelligently Designed for the Real World Beyond its sonic prowess, the 3B Cubed is an intelligent choice for any high-performance system. Its refreshingly shallow chassis depth makes it ideal for installations in custom cabinetry or racks where space is at a premium. Switchable gain settings ensure perfect synergy with any preamplifier, while its fanless, convection-cooled design guarantees completely silent operation. For the professional or custom installer, the PRO version adds rack mounting and rear-panel trim controls for precision calibration.

As with all Bryston components, the 3B Cubed is built to a standard, not a price. This commitment to excellence is backed by the legendary Bryston 20-year warranty, ensuring an investment that will deliver breathtaking musical realism for decades to come.

  • True Dual-Mono Design: Two channels, each with a fully independent power supply and transformer for ultimate channel separation.

Nice Concept, But Coverage Feels Uneven
Color: 1pc
I really like the idea of this sunscreen setting mist and I do like that it gives the skin a subtle sparkle/glowy finish. That said, the spray itself doesn’t feel evenly distributed, and it dries almost immediately, so there’s no time to blend or redistribute the product. I find myself spraying multiple times from different angles before I feel like my skin is actually covered and protected. It’s pretty and convenient in theory, but I’m not fully confident in the level of sun protection it provides.

Very pretty shimmer
Color: 1pc
This setting spray applies a very pretty glitter when used. It does have a slightly sweet smell that is almost a watermelon scent to me. The first spray or two is a bit thick, so do not spray onto your face without priming the sprayer the first time. After that first time the sprayer works perfectly, it doesn't clog and distributed a nice fine mist. It leaves my skin feeling softer and hydrated. It does not leave any greasy feeling and dries down quickly. I don't know that it does a ton for makeup setting, but as a shimmering oil and face and body mist it is great.

Not something I would order again
Color: 1pc
I had high hopes for this tinted sunscreen because the product description sounded like it would simplify my morning routine, but it ended up being a disappointment for me. The SPF 50 protection is a plus, and I appreciate that it goes on without the typical white cast. However, the tint was the biggest issue. Rather than blending naturally into my skin, it sat unevenly and emphasized dry patches and texture that aren't normally noticeable. The shade also felt limited and didn't adapt well to my skin tone, leaving an unnatural finish. The formula is marketed as hydrating and non-sticky, but I found it somewhat heavy and greasy after a few hours of wear. While it initially gives a glow, that glow quickly crossed into looking shiny. It also didn't layer particularly well under makeup and tended to pill when I applied other products on top.

Lightweight Sunscreen but Tint May Not Match All Skin Tones
Color: 1pc, Color: 1pc
This tinted sunscreen has a lightweight texture and feels comfortable on the skin. It spreads easily and doesn’t feel sticky or heavy, which makes it nice for everyday wear. I also like that it’s oil-free and provides SPF 50 broad-spectrum protection. However, the tint was a bit off for my skin tone. Instead of blending seamlessly, it left a noticeable cast that didn’t look as natural as expected. While the formula itself feels hydrating and smooth, the shade may not work well for everyone. It might work better if the tint happens to match your skin tone, but for me the color mismatch and slight cast made it less ideal as a daily tinted sunscreen.
