Krell the leader in audio engineering. Founded in 1980. Americas largest manufacturers of high end audio systems. Krell is the premier manufacturer of high end performance audio equipment. This is a beautiful silver, 5 channel in excellent condition amplifier upgradeable to 7 channel. A great piece to start your home theater. This amp pairs perfectly with the S-1200 and S1200U surround sound processor. This is a class A amplifier which has the highest sound fidelity giving you the option to use as a 2 channel for music enjoyment. It was sent in for service to Krell around 2013 or 2014, it was tested upon arrival and working according to manufacturers specs. The amplifier was then put back into the manufacturers box till date. While being serviced there were two small marks about the size of the head of a pin done to one side panel, but in my opinion they are not noticeable unless you use a magnifier. To correct the issue the manufacturer mailed me two side panels that are easy to change and will be shipped as well, bringing the condition to excellent. If you have any questions, please feel free to ask. For additional specifications just look up Krell S1500 and download manufacturers specs directly from Krell. I have been an eBay member for close to 30 years with a continuous rating of 100%. My original account which may still be active by a previous user was Dovoline.

Just this month I sold a pair of high end Sonus Faber speakers without a glitch. My descriptions are accurate and on point and a happy customer as the end result. Please note that I have included some pictures as best I can without taking it out from the box cause of the weight. If you are really interested I can take additional pictures if required.
