What is the best sounding amp for Maggies 3.7?

I have Maggies 3.6R but I want to change them on 3.7. Currently I'm using Classe CA-M400 and Audio Research VTM-200. Before I had Krell FBP200C.My amps sound very different with combination of preamps I have such as AR Ref.3,Atmasphere MP3 and Bent Audio (fully balanced passive preamp). I would like to change my amps on one of your choices just to try something else.I'm open to all suggestions weather it is tube or SS. I like open sound that includes all audiophile jargon such as depth,wide soundstage,control of speakers,detail but no lushness in sound or sweet highs.Highs need to be real with hard splashes of cymbals...ok I understand the preamp plays a great role in achieving this - MP3 and Bent Audio can do it I believe.
Thank you all for your suggestions.
