Boulder 3010 Preamplifier

The 3000 Series and thus the Boulder 3010 Preamplifier have become synonymous with the ultimate in sound quality; a level of performance reserved for only the finest audio systems in the world. But traditional thought says that the more features and functions added to a preamplifier, the more of an affect they have on sound, right?

In the 3010 Boulder’s engineers have proven traditional wisdom wrong and achieved something monumental. The 3010 is easily the greatest performing preamplifier in the history of the company. It’s also the most flexible preamp we’ve ever designed. Which very likely makes it the finest preamplifier available.

Features

Matched, dual-phase 993SD gain stage improves thermal tracking and optimizes ground

Variable Blend control allows recordings with hard-panned images or mono LPs played with stereo cartridges to create a stable center image

Ethernet connection downloads future software updates and connects to IP-based home control systems

Three balanced outputs can be operated independently for multiple zones or together for bi- or tri-amplification

Boulder's own fully-balanced volume control significantly reduces distortion and step noise

Programmable Soft mode temporarily reduces output to levels suitable for conversation

Independent, real-time controls to adjust gain on all active inputs and outputs

Separate enclosures for left and right analog sections keep all control and power circuitry from affecting sound
