Speakers for Musical Fidelity M3i

I'm running some Epic 1's with my M3i. I'm very satisfied with the combination, but that said, I've only heard this amp with some PSB Alphas and NHT Absolute Zeros in this setup. The Epics are easily the best match.

I've tried the Epics with a NAD amp and I definitely prefer the MF. Compared to the NAD, the MF definitely has a slightly sweeter top end and midrange and seems to define space within the soundstage just a little bit better.

Every once in awhile I see people questioning whether the M3i is bright and that always perplexes me as I don't consider it to be bright at all.

For sources, I use a Music Hall TT and an Oppo BDP-95 for digital.

First thing I'd do is fool around with speaker positioning and that includes height as well. It could be a room issue too....have you had other speakers in the same room with the same setup that didn't sound bright? Unfortunately, I've never heard the X12's, so I can't comment on them.
