I owned the Bryston BP6 for years. I spoke to James Tanner at Bryston as I was contemplating the BP26, and he said the circuit topology and parts are very similar as is their sonic performance, the main difference being the BP26 has balanced connections and the outboard power supply. I didn’t need the balanced connections at the time, so given the price difference and similar sonic signature I went with the BP6 and was not disappointed in the least.
Id categorize the BP6’s sound as the ultimate straight wire with gain. The clarity and overall transparency is outstanding, and it has a very quiet yet airy backdrop that produces an amazing 3D holographic soundstage. What it absolutely does not do is add or subtract anything, including warmth, so if you like the slight warmth you’re getting from the cubed pre (Bryston seems to be going more in this direction as their models progress) you ain’t gonna get that with the BP26. It’s the penultimate truth teller. Hope this helps at least somewhat.
