Technically speaking, the BP-17 Cubed has lower distortion and is more accurate than the BP-26. (The BR-20 is an even later circuit design and is further improved.) The Bryston speakers I use along with a 2.5B Cubed amp are pretty flat so it sounds perfectly balanced to me. This stuff is so low in colorations that, for example, the various Beatles remasters sound vastly different from one another. I'm really very happy with the sound.
