AWARD WINNING – PRODUCT OF THE YEAR – GORGEOUS GRYPHON COLOSSEUM, PURE CLASS A STEREO AMPLIFIER

An exquisite, pure Class A, dual mono amplifier masterpiece, providing an absolutely magnificent soundstage, housed in a stunningly beautiful contemporary glossy piano black oval tower. The Colosseum was used to drive my Magico Q5’s – clearly one of the most challenging speakers to power, and it did so with sheer ease. I’ve since upgraded to the Mephisto Solo monoblocks, hence the sale. The unit was made for use in the USA, hence operates on 115VAC. It is in superb condition.

The Colosseum holds nothing back in its design, with dual massive shielded and isolated toroidal power transformers, weighing 60 pounds, and 340,000uF of capacitive power reserve, sourcing an output stage of 48 power transistors to deliver instantaneous power peaks of up to an insane 5,400 ground-shaking watts per channel at 0.5 Ω.

The Colosseum is capable of driving the most demanding loads with an incredibly low 0.023Ω output impedance, easily powering a 4 Ω load with 320 watts of pure Class A power.

The elegant touch display enables the user to customize the interface by selection options inclusive of: Low/Med/High or Green Bias, Brightness control, Auto Power on (input signal detection), etc.

The unit ships with the product manual, original custom flight case and 20A power cord. Buyer responsible for shipping (typically <$300) and insurance. 

Payment options: Cashiers Check or Wire Transfer payments are acceptable. Unit ships upon clearance of funds.
