Please give me your 2 cents...budget 30-50k

You guys have been great! My new fear is setup. I have always paid out the a## for this and if I build this system on my own are there people who will dial in a system for me? If I go with a local shop I will be forced to use what they sell which limits my options.

I am considering the Krell FPB 700 to drive either the 802's or 800 sig, or the Wilson Watt 6. Lexicon 12b as my prepro. Any thoughts?

That sounds like a nice system. Shouldn't be that hard to set it up.
Tuning it to the room is another story. Here's what I would do. I would
buy all of those components used. All of them appear regularly on
Audiogon and can be had for about 60% of MSRP. Take the savings and
hire an independant acoustics consultant to tune your system to the room. I would also make sure to install dedicated circuits to your system and do something about your AC. I would recommend Balanced Power Technologies BP-3.5 for your system. I doubt you'll find one used -- spring for a new one. It's the last one you'll ever buy.

Sabailey I owned the B&w N803 liked them, sold them and bought the Dynaudio's Contour's and love them.

If you are building a 2/5 system can you have a dynamic system that is still warm to the ears? Can Krell with Dyn c4 make this happen. Does the Lex 12 make his possible. I want a system that is easy to listen to, but siill gives you a punch. too much to ask? The 800's actually seemed a little flat to me.

IMO, Krell is definitely punchy, but can sound a little analytical.
If you have a warm system, pairing it with Krell might give you
all the punch for which you're looking, while also bringing your
system back towards neutral. IMO, Levinson amps a touch warmer
than Krell and without the "edge" that *can* make Krells sound
fatiguing in the wrong system. I've had both Krell FBP350 MCX's
and Levinson 436's in my system and the Levinsons stayed, but
I wouldn't hesitate to pair up the Krells in another system. Just
that for my system, the Levinsons were like baby bear's chair --
Just right. Excellent detail, solid bottom and top extension, detail
without fatigue, just a touch of warmth -- perfect -- brought
everything into balance. Personally, I would be hesitant to match
up Krell with B & W, but plenty of others do -- so take my opinion
with a grain of salt. I think the analytical B & W's sound good with
a slightly warm amp. I heard the N802 with a Plinius SA250 Mark IV
and that was a great combo -- the plinius added a little warmth to
the analytical B & W sound, while pumping enough class A juice to
make them sing. B & W need lots of juice, so -- IMO -- tube gear
is out. This is why I originally suggested Levinson 436's with the
N802's. The Lexicon is pretty neutral to my ear. In your price range,
I would encourage you to audition Watt/Puppy7's. Kharma is another
speaker youy might consider, and -- again -- Joseph Audio Pearls.
