These are great amps. I've used them on my Focal Scala speakers and they sparkle. I've recently upgraded to tubes and still think these amps are remarkable for the price point. I highly recommend them. My price is firm (don't ask) - shipping is paid for by purchaser.

From the manufacturer:

The introduction of the 850 Mono Power Amplifier was the beginning of a new chapter in Boulders nearly 25 year historythe debut of a new line of products from the most respected name in home entertainment electronics.

Obviously a Boulder, the 850 at a glance reveals an unmistakable resemblance to its larger siblings, while its small footprint and monoblock simplicity mean the 850 will work in applications and locations that would be prohibitive for a conventional form factor.

The pure analog 850 avoids all the sonic problems associated with switching amplifiers, such as noise radiation, dynamic limiting, and distortion. Boulders proven linear circuit design allows you to hear your music exactly as it was recorded.

A pair of XLR inputs leads to a full-balanced, differential, three-stage input circuit, which ensures that the audio signal passes from the source to the amplifier free of distortion and noise. A muscular power supply with a massive toroidal transformer provides abundant energy to precisely control your loud speakers regardless of the source material.

Based on technology we developed for Boulders 1000 and 2000 Series, the 850s linear output section channels 200 watts of stable, high-current power into any load to reveal all of the force, delicacy, and texture hidden in your music collection. Rugged binding posts mean tight, low-impedance contacts for connecting your speaker cables without the use of tools. A complete array of protection circuits provides reliability and peace of mind. Boulderlink and a 12V trigger for external control and monitoring allow flexibility in even the most complex custom installations. Finally, metal parts fabricated on Boulders precision CNC machining centers guarantee high-quality and elegant appearance in a solid, non-resonant chassis.

As with every Boulder product, the 850 was designed, engineered, and manufactured from the ground up in our Colorado factory. With the 850 Mono Amplifier youll be amazed by the purity of your recordings and the accuracy of every note all of the impact and emotional content remain intact.
