Up for sale is one pair of Sanders Sound Systems ESL mono amplifiers. I have tested numerous amps over the last 30 years and these are my favorites. With an honest 1000 watts into 8 Ohms and over 1600 into 4, these have the power to drive ANYTHING from conventional speakers to highly reactive low impedance electrostatics. I have 3 pairs of these as well as a few of his stereo amps and am highly impressed with everything Roger sells. I am selling this barely used pair because I do not have the room any more. More details can be found on Roger's website. If you have any questions regarding the amps or the Sanders preamp I am selling on Audiogon, contact Brett at 612-423-0784 and if I do not answer, please leave a message. No texts. Paypal buyers please add 3%.
