From my personal collection a pair of B&K Reference S200.1 S2 Monoblocks in pristine condition very musical, dynamic and warm sounding. I am moving into tube equipment so selling some of my solid state equipment. the shipping weight of each monoblock is 45lbs and will be shipped double boxed. Price: $ 1350 for the pair or reasonable offer.Shipping and paypal fees extra. No low ballers please. Thanks for looking Some specs below:
Class A Pre-Driver circuitry improves low-level detail for a smoother and more musical sound.
Class AB Mosfet Output stage delivers efficient, linear power.
Balanced Inputs deliver the quietest and most accurate signal path between your preamp and amplifier.
Differential input stage with a current source load assures DC stability and wide bandwidth linearity.
Use of 1% Metal Film Resistors in the entire active circuitry to reduce noise for greater purity of sound.
Use of Toroidal Transformers and Computer Grade Capacitors to provide high current for superior dynamics and extended low frequency control.
Capability to operate at full power with a square wave input signal.
Individual External Fuse Protection prevents damage from accidental shorting of output devices, while preserving the highest level of integrity to the original signal possible
The Reference 200.1 S2 or Reference 200.2 S2 allows signal patch cables (interconnects) to be sourced
from either balanced or unbalanced preamplifier/processor outputs. A switch is used to configure a SINGLE
AMPLIFIER CHANNEL for use with either a balanced (XLR) or unbalanced (RCA) output
There is one unbalanced (RCA) input connector on the Reference 200.1 S2 and two unbalanced (RCA) input
connectors on the Reference 200.2 S2. These connectors accept an unbalanced (RCA) output from the pre-
amplifier's (RCA) volume level outputs REFERENCE 200.1 S2 Monoblock
