The Bryston 4B Cubed: The Legend, Perfected.

 

In the history of high-fidelity audio, a select few components achieve legendary status. The Bryston 4B is one of them. Since 1978, it has been the trusted powerhouse in countless recording studios and reference home systems around the world. For many music lovers, it is the definitive stereo amplifier—an icon of performance and reliability.

Now in its sixth and most advanced generation, the 4B Cubed represents the pinnacle of this storied evolution. It honours the legacy of its predecessors while elevating performance to a breathtaking new standard. The latest iteration is more powerful, more transparent, and more refined than ever before, reaffirming its position as the benchmark against which others are judged.

Authoritative Power, Unflinching Control With a commanding 300 watts per channel into 8 ohms (and a colossal 500 watts into 4 ohms), the 4B Cubed offers limitless dynamic headroom. Its true dual-mono architecture, featuring independent power supplies for each channel, provides a deep, holographic soundstage and the authority to drive any loudspeaker with absolute conviction. From the most delicate nuance to the most explosive crescendo, the 4B Cubed remains utterly composed, delivering music with effortless realism and foundational bass control.

 

The Sound of Truth This isn't just power; it's power guided by surgical precision. Utilising Bryston's patented Salomie circuitry, the 4B Cubed delivers a sound of stunning clarity and truthfulness. It adds no character of its own, serving instead as a crystal-clear window into the heart of the recording. The degree of detail, nuance, and sheer musical honesty is what has made the 4B a legend, and the Cubed version delivers it in its purest form.

The Bryston 4B has always been an aspirational component. Today, the 4B Cubed makes that dream more compelling than ever. If you've always wanted one, now is the perfect time to experience why this amplifier has remained the reference for over four decades. Backed by the legendary 20-year Bryston warranty, it's not just an amplifier—it's an heirloom.

So much pain
I had to remove these after less than 5 minutes as they caused such intense pain. The gel clings to your skin even with the lotion and tightens around your hands cutting off circulation. They have been off for about half an hour and my hands still hurt. I was so excited as I really like this brand in general. Very disappointed. Be very aware when buying.

Moisturizing Gloves That Actually Work
Over the years, I have tried so many different types of gloves to alleviate my dry skin. Since it especially bad on my hands I have tried everything. Of all the gloves I have purchased, this pair is head and shoulders above all the others. The first night I used these I could not believe the difference! It was astonishing. My hands were soft and supple for the first time in my life, and they stayed that way for most of the day. The moisturizing aspects of leaving humectants on one's skin for prolonged periods is really a game changer. They fit perfectly and can be pulled on with ease. The crazy bonus is that I was still able to use my phone once I was wearing them. That has never been the case with any of the other gloves I've used. If you have dry skin on your hands, you must try these. One night of use and you will be sold!

A bit small for one size fits all
Purchased these for my husband who has pretty severe dry skin in the winter. The gloves are great but they are a bit small. My husband doesn’t have very large hands (cadet size golfing gloves) & this hardly reaches his wrist so one size fits most is a bit of a stretch. However, these do the job & he likes them. We appreciate the packaging doubles as a reusable pouch.

Awful
I love this brand & expected more, especially for the price. the gloves are super bulky and uncomfortable. they’re hard to get on and off and have a strange feeling when on because of the gel lining. they also smell odd. i wore them so about a week with several different creams/balms/lotions etc. i woke up with them off multiple times which makes me know that i was uncomfortable in them during my sleep. they also caused a weird breakout on my hands up to my wrists that took over a week to go away with the help of cortisone. it was like hives but more rash like. i didn’t bother attempting to return them and decided to throw them out. waste of money, time & ended up with a rash at the end. they did make my hands softer and helped with my cracked skin but at what cost?

Update - Stick to your hands
UPDATED - I am SO impressed with the seller!! They read my review and gave me a full refund even though I no longer had the gloves to return. At this point I would suggest that you aren't taking a big risk to give these gloves a try, a lot of people obviously love them, and if you don't you can certainly get your money back. Many thanks to the excellent seller! __________________________________________ I bought these because it seemed like there were a lot of good reviews. I hated these! I don't understand why anyone liked them... they are lined with thick sticky gel. You know those gel like sticky toys that kids toss at a wall and it sticks? Or do you recall the sticky, gummy hands that you could toss and they would pick up a piece of paper or something? The lining of these gloves make me think of those toys. So my experience is that they are very difficult to get on and once they're on they really bugged me after awhile I need to get them off, but they're very difficult to get off without turning the gloves inside out. ...then you have to try get them turned back to right side out... in the end I tried them and then thought I would try them one more time but they were such a pain in the rear that I ended up tossing them in the trash because I waited too long to be able to return them. One of my saddest purchases from Amazon!
