Description:
The B&K Components Reference 200.7 S2 is a serious seven-channel power amplifier built for high-performance home theater and multichannel audio systems. Rated at 200 watts per channel into 8 ohms and 375 watts per channel into 4 ohms, it offers substantially more current capability and headroom than the amplification found in most conventional AV receivers.
Built in the USA during B&K’s Reference-series era, the 200.7 S2 was designed for listeners who wanted the convenience of seven channels without giving up the power and build quality of dedicated separates. It supports both balanced XLR and unbalanced RCA inputs, has a damping factor of 450, and weighs roughly 76 pounds—a good indication of how substantial the power supply and chassis are.
Highlights
- 7-channel dedicated power amplifier
- 200 watts per channel into 8 ohms
- 375 watts per channel into 4 ohms
- High-current design
- Balanced XLR and RCA inputs
- 5 Hz–45 kHz frequency response
- 450 damping factor
- 12V-style control trigger capability
- Approximately 76 lbs
- Made in the USA
- Excellent match for serious home theater systems using a separate AV processor or preamp
Ideal For:
This is a strong choice for someone who already owns an AV processor or receiver with preamp outputs and wants considerably more power for their speakers. It is especially well suited to larger rooms, demanding speakers, or seven-channel theater systems where dynamic headroom matters.
It can also make sense for someone running fewer channels who simply wants substantial dedicated amplification rather than relying on the amplifier section inside an AVR.

Why we like it:
The Reference 200.7 S2 comes from an era when B&K built large, high-current American amplifiers that were meant to last. You get 1,400 watts of rated eight-ohm amplification across seven channels in one chassis, with the flexibility of both balanced and unbalanced connections. For the right theater system, it remains a lot of amplifier for the money.
