Some useful info.
For me the choice is really simple. I don't care about THX, but I do care about the design on the 6003

I could use the extra hdmi port though :\
I thought the 7002 to be more powerfull than the 6003
The SR7002 and the SR6003 are both great designs. And if our friend the OP can use that extra HDMI input on the SR7002, the better it is.
As for the power results, I also thought originally that the 7002 was more powerful, but at close look, we can call it even.
Marantz at least is not giving more power with their newer models. And they have some pretty good efficient power supplies in their amp sections.
The Marantz SR6003 is the same equivalent (power results) than the Denon AVR-2809ci (or AVR-989), the Marantz SR7002 and the Yamaha RX-V3900.
Here's their power results at 8ohms from 0.3% THD (from Sound & Vision):
...........SR7002............SR6003............AVR-2809ci.............RX-V3900.......
1ch. = 150 watts........155 watts...........155 watts.............189 watts*.....
2ch. = 133 watts........130 watts...........130 watts.............150 watts*.....
5ch. = 93 watts.........111 watts...........112 watts*............100 watts......
7ch. = 83 watts..........96 watts...........100 watts*.............88 watts.......
* = highest # for 1,2,5 & 7 channels.
So, as you can see, they are all equal.
Now;
The SR7002 is THX Select2, Audyssey MultEQ, HDMI (4/2), 33.1 lbs, $1,400 list.
The SR6003 has Audyssey MultEQ, HDMI (3/2), 29.1 lbs, $1,100 list.
The 2809ci has Audyssey MultEQ XT, HDMI (4/1), 31 lbs, $1,200 list.
The V3900 has YPAO, HDMI (4/2), VRS ABT-2010, 38.5 lbs, $1,900 list.
So, in the end, it all boils down to extra features (# of HDMI ins & outs, Ethernet, Music streaming, USB port, type of room correction, THX, preouts for all channels, type of video processor, GUI & navigation, remote control, etc.), value (street price) and name preference (eg. Deny, Yammy, Onky, Mary or Piony), between these four receivers.
Is that make any sense at all to you guys?

Note 1: I got more similar comparisons to these with other receivers, like Onkyo TX-SR805, TX-SR876, Denon AVR-3808ci, AVR-4308ci, Yamaha RX-Z7, Pioneer SC-05, SC-07, and Marantz SR8002.
2: And also with the flagship receivers, Denon AVR-5308ci, Yamaha RX-Z11, Marantz AV8003 & MM8003 combo, Pioneer SC-09, Onkyo TX-NR906 ans Sony ES STR-DA-5400ES.
3: And I got some ideas about Arcam AVR350, Harman Kardon AVR 7550HD, Integra DTR-9.9, NAD T 785, Rotel RSX-1570 and Sunfire TGR-3.
4: Also on Separate Amps, in particular Emotiva amps, because they are in a class of their own, for performance + value.
5: Also on Surround Processors, in particular Onkyo PR-SC886P, PR-SC885P, Integra DHC-9.9, DTC-9.8, Denon AVP-A1HDCI, Anthem Statement D2/ARC, Classe SSP-800, Krell Evolution 707 ($30,000

), NAD M15 HD, Lexicon MC-12 HD, Meridian 861, Primare SP32, Simaudio Moon CP-8 and Theta Digital Casablanca III HDMI 1.3 Edition.
6: And not least, TacT TCS mkIII.

Wish I can afford that one...
* I just love this hobby.
