Bryston's new product line-up for 2013 includes a replacement for its venerable 2B stereo amplifier, the 2.5B amplifier ($2995). Similar to the new BP-17 preamplifier ($3550, see below), the 2.5B amplifier is derived from the amplifier portion of its B-135 SST2
integrated amplifier (see related story
). Bryston's James Tanner explained that the upgrade employs a much beefier power supply than its predecessor, allowing it to deliver 135Wpc into 8 ohm load impedances. Bryston's new BP-17 preamplifier ($3550) is derived from the preamplifier portion of its B-135 integrated amplifier, which features balanced outputs and advanced circuitry derived from the SP-3 surround processor. The B-17 closely resembles the B-135, differing externally only in not having heatsinks and speaker outputs on the rear panel. The BP17 utilizes a software controlled, motorized analog volume dial and integrated balance control.
