Hi,
just joined  this fabulous forum,  and new  guy to  Bryston gear, and new to audiocircle.
I need  help,   just bought  a  Bryston BP26/,  and hooked   everything up,  and having  a issue. (maybe user error)
the right  channel, for some  reason  is  making  a  hissing  sound (like driving down the road  w/  the window down)  not  very loud,  but the   left  channel  just find.  (Balanced  cable setup)
My  setup :   BP26  preamp  and 4BSST2 amp, B&W 802Di, marantz CD player.  mainly 2ch  listening.
changed out  all  the  cables, power/balanced  and  still   no  luck.
I hooked   the powersupply to BP26 and both balanced  cables  from Amp,  and hooked  CD player to preamp.
did  i  miss   something.  

could someone shed some light on my issue. 

Best Regards,
Dan
