Here's a contribution for your cartridge database - great work, I must say.http://www.diyhifi.org/forums/viewtopic ... 2227#12227
BTW I also have an Excel ES-70EX - sounds quite good - and sometime ago I tried to fill an update form on your cartridge database, because some of the data is not correct.
The page returned a database error.
