Van Den Hul The Emerald Balanced Preamplifier
The Emerald Balanced Preamplifier is a premium stereo preamp designed for ultimate audio purity and versatility. With its fully balanced architecture and innovative accumulator simulation power supply (ASPS), it minimises interference and supports flexible mixed-mode operation, enabling combinations like balanced-to-unbalanced connections. The preamp’s no-negative-feedback design and MOSFET output stages ensure high fidelity and spacious, natural sound. Precision-controlled via an aluminium infrared remote, it allows fine adjustment of levels, balance, and mute functions, all displayed on an LCD screen. Encased in a durable steel chassis for RF shielding, the Emerald delivers unmatched clarity and power, making it ideal for discerning audiophiles.
