Hello, I have just come across 2 Classe audio componets in a storage auction I purchased. I'm trying to figure out how much they may be worth and the best place to sell them. They both have some cosmetic wear and scratches. One is a very heavy amplifier. Classe Twenty-five, 2 channel or mono. It says fifteen hundred watts on the back of unit. The second is a classe audio Six. The twenty-five turns on but the six doesn't have a normal power cord. It has a strange cord that says it goes to an external power supply. If anyone has any info I would really appreciate it.
