Buying an old Superphon


I am looking at a superphon dual mono. Was wondering what matches well with it for amps and speakers.  Used of course,  also wondering what people think it is worth.

Be careful- from photos I've seen of the interior, a lot of it is held together with glue. Make sure it works correctly before shipment, and make sure that when its packed, its packed extremely well. If the preamp gets dropped too hard, it could wind up being a shock/fire hazard.


Do you have a model number? I used to have an inexpensive Superphon preamp & liked it a lot. Stan Warren designed some good equipment back in the day.
