Electrostatic Sound Systems 500 power amplifier. Classic American muscle! Serviced! $925 MSRP

Selling for $995.00

Hot rod American amp!



The ESS 500 stereo amp is a classic all American muscle. 250W per channel is what is rated on the spec sheets but the amp has been known to cross 300W with ease. Which probably explains the massive heatsink fins on the back of the amp. Its like 50% of the amp’s square footage! And the massive heatsinks are such a signature of the ESS 500 amp they are just as recognizable as the big wing 1969 Dodge Daytona. For under $1,000 now, its a no brainer to get this for its rich history and a collectible American muscle. Blue meter display offers some semblance to McIntosh’s power display (McIntosh’s way nicer of course) but its a nice touch on its own. Independent L an R gain controls allow for some additional control on the volume level on top of your preamp which is nice. The amp was recently service and had their caps and other worn out parts replaced so this amp is ready to soldier on for many more years to come.

Cosmetically, the amp looks great for its vintage. Just the usual minor scuff marks common with use. Amp will be securely packed for safe shipping.
