After having reviewed a series of tube based components from Manley Labs, I looked forward to getting a view from the other end of the spectrum when I took delivery of a solid state preamplifier and power amplifier from Bryston, a Canadian company that has been making pro audio and audiophile equipment for 40 years. Their longevity is no accident, as they are known for making great sounding, reliable, stylish gear. They also back up their reputation with a 20 year warranty, virtually unheard of in the consumer audio market. The optional remote control offers Volume Up, Volume Down, or Mute, but no source selection. The BP6 uses only discrete circuits with no IC’s in the circuit path, which Bryston says can cause distortion and non linearity. Additionally, the unit can be shipped with an internal Bryston DAC, a MM Phono Stage, and a choice of silver or black face plates in 17 or 19 inch length. ![]() Next in, I tried the 2B SST amp with the SP16. The 2B SST is also available in silver or black 17 or 19 inch faceplate. It has user selectable balanced and single ended connections. There is also a user selectable gain switch for each channel. One can select between 1V and 2V with a small toggle switch on the back panel. The amp is finished with high quality connectors and speaker binding posts. It became apparent from the get go that the 2B SST was an excellent sounding amplifier. It was like someone cleaned a dirty windshield to allow better visibility. A higher level of transparency than is available with my VS55 was evident. Bass slam and articulation was superb. The soundstage was, without a doubt, wider than I was used to. The only quibble I had at first was the slightest pinch of opaqueness in the higher frequencies. This disappeared after being powered up for a day or two and never reappeared. The overall tonal balance was neutral and the presentation was expansive, without a hint of any grain. The Bryston doubled the power of my VS55 into 8 ohms, but I did not necessarily notice a huge difference in my smallish listening room. With a larger room and power hungry speakers, you would clearly enjoy the benefits. Suffice it to say, you would be hard pressed to push the 2B SST to its limits. It also ran cool, barely producing any heat to the touch. I left it powered on for the duration of the review for optimum performance. System Set Up: After listening to the BP6 and the 2B SST separately, I then assembled a complete Bryston system, including the BCD-1 CD player Bryston sent along with the other components. The BCD-1 is very solidly built, has balanced and unbalanced connections, and uses a Crystal 192k/24bit DAC. After spinning a few CDs to get everything warmed up, I did some serious listening. The first word that came to mind is “synergy”. As a system, each component complimented the next. I had hours and hours of fatigue free music listening. Dynamics were stellar, and as noted before, the soundstage was wider than my reference system. I was enjoying clean, quiet backgrounds, detail retrieval, depth, and the extra power, even though as noted before, my room precludes rock concert levels. f Listening Session: ![]() Listening to each Bryston component separately in my reference system, then as a complete system with their own BCD-1 CD player allowed me to come to some conclusions. I believe the star of the group is the 2B SST amp. In my opinion, it is without any flaws that I can detect ergonomically or sonically. If neutral is your bag, and you are looking for a component that will probably work forever, you have found it. And if you have any doubts on the longevity, the 20 year warranty will put your mind at rest. It was an absolute pleasure to evaluate, as it provided no set up challenges. No heat producing tubes to bias, easy connectivity, selectable gain, high quality binding posts and the option of balanced connections. There is plenty of power here to boot. At $2750, I really believe this is an excellent value. To get more refinement, you will need to spend significantly more, easily as much as a quality compact car. The BP6 ($1995) is a very clean sounding and neutral preamplifier. Setup was as equally trouble free. A tape loop and two sets of outputs provide flexibility. The BP6 is ultra quiet and feels like a preamp costing at least double. The optional remote control should last a lifetime, the ability to order the unit with an internal Bryston DAC, and a phono stage really covers a lot of bases. I did try the BP6 and 2B SST with a few aftermarket tweaks. I replaced the stock power cords with my Acoustic Zen Tsunamis and immediately dynamics and overall performance improved. Symposium isolation devices improved imaging and tonal accuracy. I’m sure your experiences will vary. Conclusion: These Bryston components really grew on me. Personally suprising, as my usual preference is tube amplification. I found the grain free, dynamic and rock solid presentation very pleasing. What was missing? Well, my Audio Research gear certainly is a bit warmer in the midrange, with a more intimate presentation. My tube gear is definitely more forgiving of edgier recordings. But the Bryston set up had a truer sense of scale, and better bass control, by a mile. While those looking for more romantic presentation will want to look elsewhere, if you desire a very clean window into the recording, Bryston makes the equipment you need. I believe these components are superbly built, and are very fairly priced. Did I mention the 20 year warranty?
