Magnepan 1.6 vs. B&W 805N

I just traded in B&W 805s pair for a new set of Maggie 3.6 speakers. The B&W are nice. The Maggies are nicer. I can understand if you do not like the Maaggie sound. One problem answering your question is you do not explain what you want soundwise. Do you want better bass?, do you want a more coherent soundstage? Do you just want louder and cleaner?
I would say the maggie to B&W swap you are mentioning is basically a totally lateral swap. that is: you are NOT going better, just same yet a little different.
(And Maggie owners are fiercly loyal, you are gonna get a LOT of naysaying about your wanting to switch.. because the maggies can be pretty good sounding with great electronics.)

Having used 1.6qr's in the past with 545 & 555 Adcom amps, I can speak from experience. Those amps are SO not letting you hear what the Maggies are capable of. When you get a chance to hear what a compatible, higher quality amp brings to the party, you might very well forget the desire for another speaker. That said, it is going to put a dent in the budget buying an amp that really let the Maggies sing sweetly. In the end, that pickiness about partnered amplification was one of the reasons I switched to dynamic speakers.

When I had the 1.6's and bought an Innersound ESL amp, I couldn't believe the sound. The bass that came out of those speakers was just astounding, comparatively.

Upgrade your amp before you change speakers. There is a reason that Maggies are almost universally revered, they are great speakers.

Do you guys think classe model ten will do the job for the 1.6? It puts out 250 wpc at 4 I guess... I know bryston 4B ST is good but I need to stretch the budget a bit. I've heard a 1.6 driven by a red dragon monos and it sounds REALLY good! But I cant reach that far... :) the adcom sounds ok on some areas but Im still finding the high end sound I cant get from it.

I think you will be fine with the Classe. I imagine it puts out plenty of current which is what Maggies will want.
