MADE IN USA. Very nice example of Sumos Polaris power amp, some documents say 120 WPC @ 8 ohms, others say 100. Plenty of clean power regardless. Dual mono, MOSFET design. I have been very pleased with this amp, original MSRP back in the day $750. Sumo Athena available in a separate listing. Sorry, no box, manual or rack handles. Ships to the CONUS ONLY.

MADE IN USA. 100 WPC, Class AB, I have another that I use daily (first gen). Bought this one on a whim, untested, lost. Great look to this amp, with the rack handles. My loss might be your gain. One channel out. I really like Sumo products, have owned many, usually they are super reliable. If you are pressed for space, you can remove the rack handles for a really compact little powerhouse. Use the working channel for a subwoofer amp! Original MSRP was $800. No box or manual to include, but I pack well for shipping. 19x11.25x5.5 (including feet), 23 lbs. Ships to the CONUS ONLY via USPS or FedEx Ground.

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.
