The M-6200 approaches the concept of the power amplifier from a new vantage point. It achieves an unprecedented level of performance that again redefines what a monophonic power amplifier can be. Retaining the parallel arrangement of two completely identical amplification circuits, the M-6200 drastically lowers the noise floor and improves the damping factor. Parallel operation has the advantage of significantly bolstering output current capability, as well as enabling extremely low output impedance.

Like the INT-60, the INT-250 utilizes the synergies developed in the .8 series power amplifiers. Unlike the INT-60, however, it brings 250 watts per channel of listening pleasure. With higher power MOSFETs and more of them, the INT-250 drives large, demanding and relatively inefficient loudspeakers at higher volumes without batting an eyelash, singing beautifully. Just incredible music from one component.

The E-380 realizes a 20% increase in rated output power thanks to a reinforced power amplification stage and power supply. The further evolved AAVA volume control system allows music enjoyment at any level without even the slightest degradation of signal quality. The power amplifier section utilizes the instrumentation amplifier principle to achieve outstanding S/N ratio. Low impedance design of the output circuitry results in a damping factor of 500, ensuring that the potential of every speaker can be brought out to the fullest. Enjoy a musical performance of amazing transparency and dynamism.

"The entrance into real high-end tube amplification".

The Scorpio represents a dramatic rethinking of economic vacuum tube based integrated amplifier industrial design while retaining the basic architecture as our highly regarded "Spirit" amplifier.

The Scorpio integrated amplifier combines neutrality, realistic dynamics and power projection, true musicality with high resolution.

Perfect finish, elegant discrete design and outstanding sonic performance make the "Scorpio" unique, setting a new price-to-value standard in its class.

5-channel power amplifier with 325 watts per channel continuous power into 8 ohms. By design, P2 and P5 amplifiers are powerful independent "monoblock" amplifiers. Each channel is self-contained on its own glass-epoxy circuit board and heatsink and benefits from an independent power supply. Since there is no common audio path between channels there is a complete absence of crosstalk. Frequency-response channel matching is superb. The musical picture is seamless and exquisitely detailed with a multichannel soundstage that is astonishingly transparent, cohesive and three dimensional.

The Epsilon Monoblock immediately makes clear that its wider power bandwidth delivers more speed, top-end air and detailed resolution. It gives a precise sound, combined with an impactful bass. It has also the wonderful ability to unravel complex musical threads with grain less purity along with surprising musical dynamics. This true balanced monoblock provides perhaps the finest KT150 design performance available anywhere near its price.

The Black EX Dual Mono Amplifier is designed in a custom plated high-grade aluminium chassis that contains independent power supplies and amplifiers unique to Black EX for true dual-mono performance.

The Bel Canto REF501S is an outstanding entry point to Bel Canto standalone power amps. It has plenty of power to drive a wide variety of speakers, but has seen a significant upgrade in the quality of power over the former REF500S with Bel Canto’s custom NCore implementation. It’s an ideal match to Bel Canto’s Pre5 preamplifier, or driven directly by the Bel Canto DAC2.8 DAC control preamp.

The REF600M monoblock provides serious power, delivering the pure treble of Class A, the slam of the best Class D architectures, and the mid band presence that brings your music to life.

The E1X Stereo amplifier is designed in a sleek all-aluminium chassis using our unique constrained layer damping that provides the highest quality anti-vibration platform for high-power amplification.

When it’s time to take your audio experience to the next level the, natural move is away from an integrated amplifier to a dedicated line stage and one or more power amplifiers. The RL-102 is the obvious choice of line stage when it’s time to make that leap.

The art of technological progress, beautifully expressed in the art of visual design, in an amplifier of truly remarkable ability. Let us present to you the Boulder 1160 Stereo Power Amplifier, recognized by media and editors in the US, Taiwan, France, China, England, Japan, Poland, Hong Kong, and Italy with eleven awards for exceptional ability.

You reach out to your pocket. Therein lies the key to advanced and futuristic technology. Gently you push… The system of the ultimate sports car becomes alive. An overwhelming feeling becomes you. Almost unlimited processing power becomes available to ensure pristine performance. It’s crystal clear that you’re in the drivers seat: impressed, but in control. All instruments call out to take it for a spin. Then you realize this fine piece of machinery is reference, top notch. You are right on track with the RD- 101 Stereo DAC.

Reference 16-channel 200-watt-per-channel amplifier. Pair with AV 10 to create an elite-level home theatre. Marantz HDAM, Current Feedback Amplification, and balanced line level input.

For over 35 years, Boulder has been building the world’s highest quality audio components near Boulder, Colorado.  Boulders are cherished by music and film lovers all over the world and are instilled with quality and value that transcend the passage of time.

The 2150 Mono Power Amplifier is the beneficiary of 30 years of amplifier design. It replaces the renowned 2050 Mono Power Amplifier, a benchmark product that stayed in continuous production for almost 18 years.
