This thread is a decade old but new to me.
A pair of the Generator mono blocks will soon be on their way. They haven't been used for at least four years. The pictures I've seen of them seem to confirm that as there was a substantial layer of dust on them! The previous owner has an outstanding reputation in the HiFi community. He told me that he moved on from them as his reference amps for more power. He's going to go through them inside and out before sending them to me. He said he was never inspired to sell them.
This will be my first experience using high-end used gear.
The decision to try something different was sparked by listening to a friend's system for an extended period of time. While listening to my system the next day it hit me in the face that I wasn't getting near the potential from my speakers. My system sounded like an AM transistor radio to me! (Well maybe not quite that bad.) But it was obvious that I could use a lot more power.
The previous owner gave me a 100% guarantee! Send them back if I don't like them. But he said that I won't be sending them back!
This should be fun!
