Edirol & M-Audio monitor speakers

[Kingy75]

Hi all,
Anyone have any experience with Edirol's MA10D or MA20D or thirdly,
M-Audio's Studiophile BX5 Reference Monitors?

Any opinions to share about their performance? I produce audio backing
tracks & I'm looking for some good quality monitors (prefer powered speakers
@ present as my workspace is small). There's so many different brands of
powered monitors available it's difficult to choose a pair without hearing
them first.
Any advice is appreciated.

Thanks,
Kingy75
