Boulder 1108 Phono Stage

The 1108 is a new phono preamplifier that replaces the 1008 and slots in between the 508 and the 2108.

Because of the recent revisions and success of the 1100 Series, the last remaining component to be redesigned was the 1008 phono preamplifier.

The 1008’s appearance was a holdover from the previous 1000 Series and the changes made internally bring the new phono preamplifier up-to-date technologically. The most obvious design change is the modernized front panel and casework that now matches the rest of the 1100 Series, featuring rounded corners and topographical map detailing on the front panel.

LED colors are the same as the rest of the 1100 Series, and the button layout is much like the 1110 Preamplifier. The topography lines also match and line up with the other components in the series.

Inside, the changes include a newly designed logic control system and a new power supply. Logic control was chosen to eliminate any noise from running microprocessors that could be picked up by the initial phono high-gain stage, and the previous 1008 had the power supply located close to the control section where noise could radiate and cause problems.

We’ve also increased the operating efficiency of the power supply and pushed any supply noise to well outside of the audio band and even farther out past the bandwidth of the phono preamplifier’s gain section.

Boulder 508 Phono Stage

The 508 is the smallest, least expensive product in our product range and punches well above its weight, drawing its basic design from the iconic 2008 Phono Preamplifier.

Everything about the 508 points towards design efficiency: a chassis machined from a solid block, compact surface-mount design, a single pair of balanced inputs and outputs, a single RIAA EQ curve, simple MM/MC switching, and more.

Boulder 2160 - pictures

Every electronic circuit within the 2160 Stereo Amplifier is entirely new and all technological changes are primarily derived from Boulder’s 3050 Mono Amplifier.

Among the numerous changes and advances encompassed by the 2160 are:

Pure linear Class A operation. Bias current is actively monitored and adjusted in order to increase efficiency and reduce wasted radiated heat energy.

A new, high efficiency, microprocessor controlled standby mode reduces power consumption when engaged.

All electronic circuits and electronics are now surface-mount designs manufactured on Boulder’s own surface-mount manufacturing machines and ovens to increase reliability, consistency and optimized ground planing while at the same time reducing signal path length, PCB capacitance and noise radiation.

Gain stages within the 2160 are Boulder’s proprietary 99H2, which is unique to the 2100 Series amplifiers. 99H2 gain stages feature surface-mount electronic design and feature a new machined and potted housing to increase thermal stability.

The 2160 generate power output of up to 600 watts into any load, enabling massive current swings and the ability to drive any loudspeaker to realistic audio levels.
