You dont need to. Monarch 2 is the best for me, not even considering the price.
I’d demoed/bought many IEMs, some even 2-3 times the price of monarch, and I sold everything, and bought Monarch mk2 new.
I am happy and sad now, happy coz I found my love ones, but sad coz I have no appetite to upgrade anymore. :)
Monarch mk2.
I sold almost everything else because of this iem. Coz its so good that I dont feel like i want to use anything else, and i have tried and own some other iems that cost 2-3 times the price.
I mainly listen to pop, jazz, classical.
