Guys thanks for all the great recommendations:
Harbeth P3ESR - I heard only good thing about this speakers, but I just wonder how much improvement compare to the Wharfedale Denton I currently own, it can be just not much I get, especially in terms of bass, dynamic and power? The Malaysia price of this is enough to buy a larger monitor
ProAc SC1 or D2 - Actually I'm wainting someone to let go, but I just keep waiting, no news yet...
Omega, Fritz, Reference 3A, Speaker Art, Tekton speakers - I'm afraid I'm not able to audition these great speakers at Malaysia because simply N/A
KEF LS50 / R300 - The price is indeed very high at Malaysia here, they are really famous anywhere I've seen in shops, I feel a bit hesitate to audition KEF LS50 as I think the bass would be quite limited for orchestra music, physical driver size limitation just always happen to me when listening to smaller speakers, indeed I'm looking for medium size speakers, not too small not big like floorstander, something like 6.5inch woofer driver, with almost perfect tonal balance, KEF R300 would be a great option consider that, but then the price is shockingly high, almost absurd if it make sense to me
My best bet would be used item like Dynaudio Focus series, or ProAc D2 which very rare in sale, another option I'm eagerly waiting to audition is Sonus Faber Venere 1.5/2.0, the resell price is indeed very attractive, half of original sale price, but that would be curious to me why?
