Oh I've passed on them many times now. I'm wondering if it's some way to customize your own house curve or... hold up...
Or you're absolutely correct! It's like you have a spider sense for this crap! Ha ha.
RC Networks: All Merlin TSMs come with a pair of RC Networks. What are RC Networks? They are simple a resistor capacitor network (sometimes referred to as a Zobel Network in design circles) that mounts across your speaker terminals. The network acts to terminate the speakers load out past the audio band up into RF regions (this keeps amplifiers a bit more happy) and they also act a shunt or load for RFI energy that appears at the speakers terminals (whether picked up by the speaker, the speaker cables, are fed from further up the line in your HiFi system). The result is a cleaner and more uniform sound from the speaker/amplifier system. Merlin has learned over the years that the quality and type of parts used to make the RC Network are very important and do have a impact on the sound. The Standard RC Networks are made with a Cryogenically treated Hovland capacitor and a Caddock Metal Film deposition resistor and Cardas wiring. The Master RC Networks use the (very good & expensive) hand made Deuland capacitors (see BAM Differences above for the impact these caps have in the Master BAM – they do much the same thing here) and cost much more than the Standard RC’s.
I really was trying to follow that, then I got to the "Cryogenically treated" part...
