I have decided and returned back the Tascam VL-S21 and got back the other pair of monitors I had before. The reason why is that for the price I think that the Ediro MA-7A monitors were actualy more flatter than the Tascam's. I think the reason why that the Tascam's are not as flat as Edirol's is because Tascam's use a sub to make the bass and usualy subs put out alot more bass than normal pair of monitors.
