M100 speakers are over 30 years old and had never been serviced.
John replaced power supply caps and input sockets. (the originals feel off)
He also worked some other magic to the speakers.
The G92 had a new power supply and again other magic.
The character of the system is the same, I love it. However, there is now more depth to the overall sound, top and mid is super smooth, and the bass has depth and foundation. Just a lot more than it had before.
Every penny has been well spent.Thanks John
