Headphoneus Supremus
Replaced my Bryston .5 preamp and Creek OBH-11se Rev B for a Bryston BP25P awhile back.
Problem though the BP25P does not drive the Grado SR325i’s and my AKG K501’s with any authority, my HD580’s at 300ohms though sound very good with the BP25P.
So what I thought it would be fun to possible modify the Bryton .5 and turn it into a dedicated headamp.
I’m assuming the gain and current would have to be increased at the lineouts to accommodate the lower impedance cans such as the Grado’s .
Here is the path to the BP5 schematics,

the .5 is the same but without the balance outputs, for those who would like to contribute possible procedures. I’m handy with an iron but not an electrical wiz.
