Balanced preamp tube for Magnepan 3.6 or 20.1


Please, an excellent totally balanced preamp for Magnepan 3.6 or 20.1 I can consider? I have two Mcintosh mc501 and one mc402 as amps. Someone told me BAT VK-31SE, VTL and others Audio Research LS-26. I would to obtein an open scene with a clear, detailed sound and a powerful warm bass in general.
I don't know the best combination with Mcintosh solid state amps.
Thanks for your helps,

ARC Ref 3 or Cary SLP05, both will work extremely well. Giving you a very open soundstage and excellent bass. I think that Cary is slightly warmer than the ARC. I have never heard the BAT's or VTL's.

I have the 3.6R's and have tried both the 501's and the 402 Mac's and never gotten good results. They are great amps which sound fantastic with other speakers, and I am not sure why, but they sounded muddled and weak with my system(s). I love the Cary MB500's that I have, and I have tried many amps with my Maggies. Then probably the Sanders Sound ESL amps (formerly Innersound). VTL amps sound sublime too. I love the previous generation of them, especially the aesthtics.
Thanks to all for your help. I'm reading all your messages to understand well what I have to do!
thanks a lot
Andrea
