BMC Product Lineup

BMC PureDAC – $1790

BMC Reference DAC1 – $5690 DAC1, $6290 DAC1 + Preamp

BMC MCCI Phono Stage – $3890

The BMC MCCI Phono Stage is a truly balanced, global feedback free, passively equalised moving coil phono pre-amplifier with the exceptional Current Injection input and LEF single ended class-A output stages.

The vinyl disc, dinosaur of music recording formats, only barely survived the CD. Today,however, the quality of turntables, tone-arms, and cartridges have increased to unprecedented levels, which vinyl recording producers support by pressing higher quality discs in limited quantities. This means new challenges as well as new opportunities for phono amplifiers.

The only consistent way to process the delicate music signal from a moving coil cartridge is with a balanced Current Injection (CI) input as the cartridge’s signal is among the most sensitive an audio amplifier circuit will encounter. Using CI, the current of the moving coil flows through the phono amplifier, including the first half of the RIAA equalization. The result is a level of dynamics, impact, spaciousness and richness of color that surpasses the performance of step-up transformers as well as the usual voltage inputs.

At the same time, Current Injection electrically damps the moving coil cartridge by letting energy flow into the CI input, instead of eliminating it in a cartridge load resistor. Transformed energy sounds different than and superior to eliminated energy.

B.M.C.’s use of distortion-free circuits with a Current Injection input and a Load-Effect Free output brings to listeners an advanced musical experience — exceptionally lifelike, open and natural.

Combining the CI input with a low impedance moving coil cartridge give new meaning to the phrase “dynamic system.”

B.M.C.’s Phono MCCI is exceptional, and easily among the best MC phono preamps available today at any price. Its sound was startlingly good, and in some ways seemed to surpass that of virtually every other phono preamp I’ve heard, especially in terms of transparency, and of not imposing its own strong character, or any character, on the music.

BMC CS2 Integrated Amplifier – $8390

B.M.C.’s AMP CS2 is a Load-Effect Free (LEF) Amplifier with an option to upgrade it to a LEF Stereo Power Amplifier. The crucial secret of the CS2’s sound is that it avoids distortion, instead of compensating for it through a negative feedback loop.

LEF = Load Effect Free

The AMP CS2 is a power amplifier without a preamplifier for a short, pure signal path. It features a Volume Control using our exclusive Discrete Intelligent Gain Management (DIGM) system, and an input selector. The lossless DIGM volume adjustment eliminates unnecessary signal attenuation at the input, as well as unnecessary high amplification.

Combining the AMP CS2 with a B.M.C. Digital-to-Analog Converter (DAC) transforms it into a LEF stereo power amplifier that offers DIGM gain adjustment set by the DAC’s volume control. In addition, B.M.C.’s balanced Current Injection (CI) input enhances the immediacy of reproduced music by processing the signal current of the source until it reaches the speaker’s output voltage. B.M.C.’s LEF output stage avoids distortion before it occurs by relieving the sound-critical LEF single-ended Class-A transistor of all duties other than providing perfect signal reproduction.

Unlike other amplifiers, a LEF amplifier handles a speaker’s current demand separately from the voltage demand. The result is an unparalleled mastery of musical complexity that brings to startling life delicate details, rock-shaking power, high dynamics, sonic vitality, and accurate imaging — all on a three-dimensional soundstage.

Load-Effect Free amplification is a new experience that must be heard to be fully appreciated.

The AMP CS2 also boasts solid output power: 2 x 200 watts into 8 ohms, and 2 x 350 watts into 4 ohms.

A fully regulated power supply with a 2kW toroidal transformer and balanced current capacitors provide the muscle behind the music.

BMC M2 Monoblock Amplifier – $7990/each

B.M.C.’s M2 is a distortion-free LEF Mono Power Amplifier with adjustable gain DIGM and a balanced XLR-CI input. The AMP M1 can also be used as a classical monaural power amplifier.

LEF = Load-Effect Free

In the short B.M.C. signal chain, the unattenuated signal is used from the fixed output of the source, while our exclusive DIGM system adjusts the volume by setting the gain of the amplifier. The lossless volume-setting happens at the B.M.C. DAC 1, which optically transmits the desired value to the M2.

Tonal and technical crème de la crème: B.M.C.’s balanced Current Injection (CI) input imparts an even more intense musical experience by processing the original signal current until it generates the adjustable speaker output voltage.

The channel separation by two separate mono power amplifiers cannot be surpassed.

A fully regulated power supply with a 2kW toroidal transformer and Balanced Current capacitors delivers a silent background and rock-solid stability.

The Load-Effect Free (LEF) output stage avoids any distortion before it occurs by relieving the sound-critical single-ended Class-A transistor of all duties other than providing perfect signal reproduction.

Unlike other amplifiers, a LEF amplifier handles a speaker’s current demand separately from the voltage demand. The result is an unparallelled mastery of musical complexity that brings to startling life delicate details, rock-shaking power, high dynamics, sonic vitality, and accurate imaging — all on a three-dimensional soundstage.

Load-Effect Free amplification is a new experience.

The M2 also boasts solid output power: 200 watts into 8 ohms, 380 watts into 4 ohms.
