There are people who do mods for ARC preamps if you really want to upgrade this is much more economical. can't remember who, sorry, they're in canada somewhere, perhaps there are others as well.
ARC LS5mkIII: Is it old sound!
I have enjoyed my LS5III for the last three years, longer than I have kept any one piece of equipment. With the advancement of technology from ARC, more specifically the LS25 and LS16, will I be getting a better sounding preamp. More specifically, is the LS5III worth hanging onto or is its time up. Thank you in advance.
