You should read Jeff Fritz’s articles on Sound Stage Ultra when he decided to revamp his system from a mega expensive to a fixed budget. While he was deciding on amps in the 20k - 40k range he got an old CODA Class A amp as a temporary placeholder amp. He was shocked at how good it sounded relative to the latest amps he was auditioning. I think it was the CODA 11.
There is a seller close to where I live that has a CODA 11 for sale. It has intrigued me for my $1000 Magnepan LRS+ speakers. My CODA #16 is incredible on the LRS+ but it is needed elsewhere.
