Avantone CLA-200 Studio Reference Power Amplifier

I'm the original owner. Purchased from Zzounds in October 2020. Amplifier is in near mint condition with no scratches, scuffs, nicks, etc. anywhere on it. It was used to power a pair of KEF LS50 speakers in a computer audio system in a smoke/pet free home. I switched to powered speakers, so the amp is not needed. All original items (boxes, manual, packing, etc.) included.

From the Avantone Pro website:  The Avantone Pro CLA-200 Studio Reference Amplifier is a classically designed Class A/B amplifier. We took particular care to create an amplifier in the traditional studio style, with generous VU meters, high quality Japanese components and a serious toroidal transformer linear power supply. In a standard 2U rack mount chassis, this amplifier can generate over 200 watts per channel into an 8 ohm load, making it perfect for medium to large speakers in a studio environment. The CLA-200 is convection cooled – no fan noise, so it can be used in the same room as the monitors.

The Avantone Pro CLA-200 Studio Reference Amplifier is a dynamic, high output, high resolution, full-range system built the old school way. We included no-compromise components in a 2U convection cooled chassis to complement our CLA-10 Studio Reference Monitors. Of course, it can be used with any passive studio monitor requiring serious dynamic range.

The CLA-200 Studio Reference Amplifier is designed to be used in a studio environment requiring high power output with no fan noise. Under testing, it delivers a powerful 208 watts into 8 ohms and can run at one third power without thermal fault. The CLA-200 has zero fan noise, as it’s convection cooled — which makes it perfectly suited for control room installation.
