I have a Creek OBH-21 which is usually fed by the tape output of my LFD main amplifier, and sometimes directly from a cd player. The problem I have is that the former option gives me much more limited volume output and dynamics than the latter. Unfortunately, I am unable to find tape output mV specs for the LFD, so am unable to rule that out as an option. Unfortunately, I also cannot compare with another headphone amp :-(
Does anybody have any ideas on possible diagnoses and remedies? Is this something familiar to other Creek users, perhaps?
PS. Headphones used: Sennheiser HD650, AKG K550 and AKG K601. All behave the same.
