Sumo Polaris II power amplifier. Owned from new, original packaging. This is the Mk II version of this highly regarded amplifier, renowned for being at the excellent value end of the US MosFET amplifiers. 110WPC and has a fantastically vibrant, balanced, controlled sound. Owned by me from new (purchased from Sounds Exclusive in Cranleigh) and used with Spendor, Linn and Martin Logan loudspeakers. Good condition, with a number of superficial scuffs and scratches (Ive tried ensure that these are shown in the photographs). Not used for two years, but Ive just hooked it up and tested it, and its working beautifully. Ive included an estimated shipping fee (UK only) - with a large item like an amplifier, this varies greatly depending on where you are. For the winning bidder, I can either deliver central Scotland for the listed fee or will charge actual courier fees at cost.
