NAD vs. MF Amp - best match best choice?


I've narrowed down my choices to match with my PSB tower speakers (X2Ts) between an NAD 375 BEE (same company as PSB) or a Musical Fidelity M3i or possibly used M6i. So basically my price range is $1700 for the M6i used or maybe half that cost for a used NAD 375 or M3i.

Need help choosing!! i could always put more towards an upgraded DAC with the money saved but if the M6i is a large upgrade, then I"ll go with that amp. Looking for large soundstage, good bass control.

Thanks for your advice!

I went from NAD C372 to MF M6PRE/M6PRX with B&W speakers. My impressions are consistent with what Georgelofi has said.
George, wouldn't a glossary of Universal terms and meanings be nice.... We tried to do this about 30 years ago and at that time we took etched to mean edgy... etched glass or metal is "cut into".... "sharp edges" no argument with how you used the term, just an explanation of where mine came from.
Etched, to me means well defined leading start to notes or transients, and not softened.
If something was edgy I would use the word harsh or hard.

But saying that, an etched sounding amp could sound hard in with the wrong speakers or source.

EG: I would never use an etched sounding amp with a pair of Heil Air Motion tweeters, that sound to me would then be hard or harsh. To quote a Monty Python saying, "it would rip your bloody ears off"
