This 7 channel NAD M25 has a bad power supply. One of it's electrolytic capacitors overheated due to irregular home voltage regulation over the years. NAD has since came out with a new power supply board with beefier capacitors to handle irregular voltages. This was diagnosed by both NAD customer service after I took it apart myself as well as NAD authorized dealer from Las Angelas. I was quoted $780 to fix including parts and labor to fix however, I don't want to make that 4 hour drive twice. Therefore I'm parting out or selling as a whole.
For a total of $1300 for the unit plus repair, you could have a basically new M25 worth $2200 as they generally go for this amount refurbished. Local pickup is preferred.
