Thanks everybody for your suggestions, appreciated
Mainly: Willsound MK2 rev2, MK1 rev2 (sold recently but can still remember well). If it can help I still have the following to compare : EMX500S, Edifier H180, VE Monk (rev1)
Can you please tell me what difference you really feel between those models in bass domain? because to me it's like 2 different worlds yet.
Thank you very much for your reply, I will let them burn for at least 150 hours and I will report back
All you listed (except monk 1,haven't heard of it) are bass heavy hitters. When compared to the PK32 immediately after listening to the others listed, the PK32 might sound lighter on bass.. But i still think it's odd because before burning the PK32 sounds the bassiest (more midbass), well at least the one i have. Even now the bass on my unit is still have ample amount after hours of use
