I have a 5 year old reference 30 pre-amp. Someone who knows about these things suggested that I send my unit in to B&K for a firmware upgrade (essentially to the audio processing of the reference 50), For this, they want $500.
Any thoughts out there is to whether this is worth doing? Thanks
I have a ref 30 that I upgraded to ref 31 (ref 50 spec) a couple years ago. Sound is about the same for TV/DVD, a little cleaner for music. The big thing is that it fixed most of the problems I had been having (clicks & dropouts). It was money well spent for me.
