Will I be getting night and day difference in terms of SQ if I compare the Edifier range (R1900T3, R2000T) against more expensive ones like M-Audio AV40 or even KRK Rokit 5?

Don't wanna spend double or even triple the amount maybe and ending up the Edifier could deliver comparable or almost equal results..

Is there anywhere I can demo the M-Audios or KRKs first before making a decision?

Thanks!
