Holton Five-Zero-Zero Supreme


The Holton Five-Zero-Zero Supreme is the latest design from Holton Audio and is a true dual mono bloc power amplifier encapsulated in one chassis.

Featuring a 2KVA toroidal power transformer which is suspended underneath the main amplifier circuitry mounted on its own mezzanine floor. The power supply features 300,000uf of storage and extensive additional supply decoupling on the input VAS driver stages. The new supreme also has additional MOSFET driver stage to tightly control the main Dual Die MOSFET output stage, resulting in much improved bass authority and extention; improved imaging and spacial 3D sound stage control.

The enlarged power output stage on the Holton 500 Supreme allows 2 ohm loads to be driven to 750 watts RMS per channel allowing even the most demanding loudspeakers to be powered with ease.
