Probably bigger sound stage as well. Unfortunately I just don’t have enough fund at this stage. This will be my future plan also.Hello ! Yesterday I received the second Power Supply Unit enabling my C10 to run in Mono configuration. Well what should I say: everything is better, more beautiful, calmer with more sovereignty but also much more quietness and details, instruments with more body etc etc. Just staggering. Not cheap though but I encourage everyone who owns or is considering of owning the fabulous C10 to try the 3 box (2x PS) mono version.
