CLASS D
POWER AMPLIFIERS

Class-D power amplifier

DESIGN & POWER WITH EFFICIENCY

Our Class D power amplifiers can use one or two class D Hypex modules with NCORE technology powered by one or two 1200 W switched-mode power supply or the high performance 1ET400A Purifi Audio module.

The Class D power amplifiers are assembled entirely by hand in an artisanal way and it is contained in a anti-vibration monobloc aluminium chassis of exclusive design, with independent compartments for the power amplifier section and the power supply section. All connections are Furutech. The input buffer is specifically designed and manufactured with very low noise operational amplifiers from the manufacturer Sonic Imagery Labs and very low noise Sparkoslabs voltage regulators.

INPUT BUFFER

Specific design and manufacturing input buffer with Korg NuTube triode valve with very low noise voltage regulators.

COLORS

Choose between six different colors for the chassis: black, red, blue, gold, silver and chrome.
