Finally took the Bryston 4B Cubed plunge


Back in January, I solicited folks on the forum for input on the Bryston 4B cubed amp. I was kicking around the idea of replacing my Parasound A21 amp. After dealing with poor health for the past few months, I finally did it! My take on the Bryston is: it's a keeper. It is a better sounding amp than my A21, but by only a very small margin. The Bryston gives the feel of being in a concert hall. An extremely full sounding amp with great detail and there's more emphasis on instrument placement than I've experienced before. The bass doesn't suffer at all either, very tight and clear. In comparison only to the two amps I'm discussing, if the Bryston were a "10", the Parasound would be a close "9". If I were to improve on my system (God forbid, I already have $35K into it), the 4B cubed would definitely be driving it. A premium solid state amp. 
To all the the forum members that were willing to guide me with their opinions, I give a heartfelt thanks. My previous posts (inquiries) were met with sincerity and am grateful that none of the discussion went off the rails. A few members contacted me personally, some I couldn't respond to. I didn't try to ignore anyone, there's simply a downside to old age and a weak heart.

@fsonicsmith in fairness and full disclosure, I'm actually a reviewer so it's my job to try to be as objective as possible. :) And the Brystons are on loan for review. I try not to be a brand groupie, and ultimately all I care about is how good the gear and sound is regardless of brand, but hey I'm human and there are a few that I have a soft spot for. Anyway you raise a LOT of great points and questions that I could go on and on about, I will try to respond as succinctly as I can...

Re: Bryston missing the mark on "transparency and inner detail," I think this is a fair criticism. I'm not as familiar with the SST2 and older lines, but my friend Marty DeWulf spent some time with them and I think he would agree with you. My best guess is the Cubed series makes pretty big strides here, and gets much closer to hitting the mark. It's still not Pass or Ayre, but it's pretty good. 

Re: why they don't try to go after the super high-end crowd, I think it's pretty simple: culture and business model. I don't think our target market is a very good one from a financial perspective. It's way too niche and full of crazies like me. We're super subjective and fickle and it just goes against the grain of the pragmatic, engineering-centric and quality-driven culture of Bryston. Also in terms of design philosophy, the types of things that matter to purist audiophiles - minimalism, zero feedback, etc. - actually go against the grain of what Bryston designs for. Everything is a trade-off, and they make certain design decisions based on specific objectives. One of them is absolute reliability - the protection circuits in a Bryston amp may actually take a little away from the sound, but they make the unit bulletproof. A 4B3 would thrive in environments - studios, stages, theater basements, school auditoriums, etc. - that would make a typical high-end amp cry, or probably burst into flames. Case in point - I accidentally pulled the power cord out of the 4B3 mid-operation. The amp instantaneously muted as if I had turned it off properly, surely and gracefully. Not a single thump or moment of drama for my speakers or ears. Same for the preamp. The stuff is indestructible and impervious to idiocy, and if you do somehow overwhelm the failsafes, there's a good chance Bryston will fix it for you anyway. That takes a certain commitment and design ethos that while not diametrically opposed to the purist approach, certainly isn't congruent with it.

I think when you factor the above and the warranty into the price of the Bryston, it would be reasonable to expect their $5k amp to be in the same sound-quality league as an audiophile amp at about half the price. Again, trade-ofs - all that design stuff takes time and money that could have been spent on tweaking ultimate sound quality. The fact that the 4B3 actually sounds very much in line with its price, AND checks all the traditional Bryston boxes, is kind of remarkable methinks.

As to why they are going into tables, again, simple - market factors. Analog is hot and distinct from the high-end market - LPs are actually cool and hipster and there is a younger demographic buying them. Compare this to the typical crowd at an audio show, that, no offense, is more likely to be collecting Social Security benefits than paying off student loans. Analog has become a viable, sustainable market (for now at least), and in business, either you cash in or get pushed out. 

And you can't fault Bryston for going after a solid business model. What's the point of offering a 20 year warranty if you can't stay in business that long! :)  In fact you could say that in order to take care of their core customer base well into the future, they did the math and made some business projections and decisions to ensure financial health. The audio industry is deep into an existential crisis and I don't blame anyone for trying to stay alive.
@professorsvsu I'm glad you're enjoying your 4B3 even more now after some more run-in. TBH, when you said it was only a little better than your Parasound, I raised my eyebrows a bit and thought to myself, that Bryston either isn't set up properly or run in enough. ;)
Thank You - tawwGood to read that Audience cabling is a sonic match w/ Bryston. Transparent Audio is as well. I have not heard the newer lines (SE nor SX).Even the very 1st line of cabling and power cords still holds up.
If I decide to go this way, the BP-26 pre-amp, maybe too much for a simple 2-channel CD/SACD system. I hope to get a demo on the BP-17.
Happy Listening!
@jafant my friend is sending me some of the older Audience cables, I think possibly the original Au24, for comparison with the SX. So I should have a sense of how they work with the Bryston, if you decide to pick up an old set or what not.
Thank You - taww
Yes, Audience started with the original "Au" series and "e" power cord.I have heard those models roughly 10years ago. Not bad at all to my ears.No question the SE and SX built upon the early success and took a good line to excellence.
I look forward in reading about your thoughts and impressions.Happy Listening!
