A complete overhaul: B&W, AMP sunfire, nad, denon

I am in the process of an overhaul, and I might have started in the wrong end (started with speakers), but now I am here:

- Speakers: B&W 803D,B&W HTM3,B&W CDM(surround)
- HT Reciever Denon 4306
- AMPs:
(NAD S200 and S100 for my front, preout denon to s100 to s200)
(NAD 216 mono for HTM3)
(use the denon for my Surrounds)
- Denon 3910 DVD

---- what i would like ---
- Goals: Better HT AND better 2-channel sound for hifi.
- Less mess and not having to change on the S100 for listening to good 2 channel, but rather everything collected. (FYI) I have no problem with more units if it gets me better sound.
- I need in my HT part (reciever or HT preamp:
hdmi 1.3 in and out (at least 1 out and 3 in)
new formats of HD-DD, DTS-HD etc
1080p scaling out to HDMI
- being able to drive my 803D and other speakers very well

---- My ideas --
I am thinking of buying a good HT pre-amp which I can use for both HT and 2ch.
**Candidate: denon AVP-A1HD (preamp only)
(see http://www.avsforum.com/avs-vb/showthread.php?t=849455)
It has everything i need in HT, but as a 2ch preamp I am not capable of comparing it to a good 2ch preamp or other HT alternative that I can use for 2ch too. My hypothesis is that it is only a pre-amp ht (no amp with current messing things up for sound etc) and it has balanced out.

For an AMP I am thinking about a Sunfire TGA-7400, 7ch 400W, 8ohm. I use 5.1, but thought I could biamp my front with the two extra channels.
I have also looked at e.g. the Cinenova Grande 7-Channel (earthquake) but to tell you the truth in this price bracket I have no clue.

An alternative total is a Classe setup w. pre-amp and their 5200 amp, but its a lot more expensive AND the pre-amp from classe isnt even close in features. The amp itself is very expensive in comparison to e.g. the sunfire.

If you want to gauge my budget say about 12000USD.

Now I know many people post questions, but I really need help and would greatly appreciate help.

Thank you.
I, too, own the Denon 3910 DVD player and based on its audio performance I wouldn't have any hesitations of using a high-end Denon pre/pro, especially with the Audyssey room correction, for 2-channel listening.

I wouldn't sweat the multichannel amp at all. Simply pick something that has ample power to drive your speakers. Since the Denon has balanced outpus, I'd only consider amps with balanced connections. My standard recommendation is Bryston, Parasound and ATI. The ATI AT3000 series is very tough to beat. http://www.ati-amp.com/at3000.html
For HT, let your receiver power the center/surrounds and pass the L/R HT signal through a nice two channel preamp and dedicated two channel amp for your 803Ds.

For two channel, run direct from your 3910 (2 channel outs)to your nice preamp! ...voila.
Bob, I took a look at the ATI, a question. I could not see if the two extra channels (out of 2) could be used to biamp the front.
One other thing, do you mean that you would rather have the ATI than the sunfire?

I'm not sure I understand your question. The AT3000 series of multichannel amps can be configured from 2 channels up to 7 channels. Each channel has its own input so if you want to use a pair of channels for one speaker you'll feed both channels the same input designated for that speaker. For example, the preamp output for the left speaker could go to amp channels 4 & 5, which would then go to the left speaker Low & High.

I've never used a Sunfire amp before, so I really can't say I prefer one over the other, but the layout of the rear panel of the ATI looks easier to use to me, i.e., cable layout.
