Best matching amp for Wilson W/P6, any sudgestions

I have the Wilson/P7's and have tried the Edge,Classe,Krell, Bermaster, VTL,Quicksilver V4 monos, NAim,Lamm and Spectral amps. I Also the Mark Levinson Amps. I found that the Levinson 334 Amp the best. I was hoping to find a need for more power and therefore up grade to the 336 or the new 436. But Power and definition was not a problem. I also evaluated Preamps in various Combinations: Edge, Aestheticx calypso,Lamm,Classe and Levinson. I do not feel that tubes get the most out of these speakers. I really thought I would because of the great reviews of the LAMM and Aestheticx products. The transparency and tightness of instruments was lost. Also each Amp works differently with each preamp. Ultimately , I found the N32 Levinson preamp to work the best with the Levinson Amp and Wilson speakers. let me know what you think.

I just changed my AMP from the Levinson to Pass XA 160. The overall sound was richer with a larger soundstage. The individual background instruments became more noticeable and therefore three dimensional. The base is more defined. The Levinson throws the vocals dramatically out toward the listener and demands attention slightly at the expense of other less powerful notes. This is not to say the Levinson is not extremely detailed and well imaged. It is, but after listening to the Pass I notice more air around the notes. The vocals are fuller and expand all around you. Suttle background Cymbals float effortlessly. I highly recommend a try with Wilson 6 or 7 but not 5 because of difference in ohms.
