Is Marantz AV8805 good enough pre amp for McIntosh MC8207


In the market for a new preamp to hook up to my MC8207 and was wondering if the Marantz AV8805 is worth the investment. I was gonna go with the McIntosh MX-122 but that thing is already outdated when it comes to new features and it costs twice as much. I don't have a store to go to to listen to the AV8805 and this is gonna be a blind buy for me this time. This setup is gonna be for my new home theater room that I am about to start building and planning to add another McIntosh amp down the road for the rest of the speakers and probably it's gonna be another MC8207 to be able to fully use the 8805.

Sorry cause first I didn't know what your speakers were. My bad. Yes, what you currently have are more than good enough for your B&W 683 S2. I think the Mac is somewhat overkill for your speakers. The Rotel amp will do just fine for your 683 S2. 
@auxinput I still haven't gotten it yet, it will be few days until it comes to my house. Once I get it and install it I will let you know my thoughts and I think that I will like it because I am coming from a very old almost 20 year old receiver which is Onkyo that was paired with some shitty Polk speakers. Few months ago I upgraded the speakers and got the B&W's 600 S2 series speakers, I got a pair of 683 S2 Floorstanding, HTM61 S2 Center and 2 pairs of 685 S2 bookshelves to give me that 7.1 surround. I will be upgrading my sub and will get 2 of them and think that i will go with REL or JL. Also looking for suggestion for my Atmos speakers I want to get 4 of them for the Tops/Heights.
I have had the 8805 in my video room for over a month now. It is a very nice sounding piece. It is significantly more open and better sounding than my twenty year old Theta Casanova. It integrates well with my rotel/ Focal setup. I recommend this piece for those who want a hybrid, both 2 channel listening and want a state of the art theater room. The Audysey Platinum software makes tuning a room a breeze. 
I have been using the  8802A for about 18 months with Bryston amps . I cannot say enough about the Marantz.  very musical in 2 Channel and 7.1.  the connectivity of the Marantz is endless and easy to set up.  new ones are selling for approximately $2200 now.  
you will not notice or hear any difference between the 8802A and the 8805.  unless youre into having the latest and greatest, Save yourself $3,000 and get the 8802A IMO.
