I owned a RWAK240 and tested the Calyx M. The M indeed sounds bigger and in a way more engaging. I was concerned however that this type of colored sound, although very tasty at first might be too much after a while. And might not pair well with warmer iems such as the Roxannes. Anyways the reason why I will not get it is mostly size...I find the M quite unwieldy.
Sounds like you no longer have the RWAK240?
