Thoughts on potential new system?


Just went to a Magnolia Design Center and did some looking and listening. My wife and I started with the Sonus Faber 2.5 and 3.0. 3.0 was a big step up from 2.5, but still not great. (For reference, our stereo system is Magnepan 20.1 with AR Reference 3 and Cary Monoblocks). Anyway, tried the B&W speakers and liked them but my wife's ears found the treble a bit harsh at times. I thought they were good, but a bit sterile and brighter in character. Eventually settled on Sonus Faber Olympia 3 as our favorite. Thinking of the Olympia 2 in a HT setup to save a few dollars. Here is their recommended system with the TV (75" Samsung 8550).

Sonus Faber Olympia 2 fronts, Olympia Center, and some in ceiling rears (necessitated by room, unfortunately).
McIntosh 5 channel amp, 200wpc
Marantz pre/pro
Oppo 105 player
REL S3 sub

Any thoughts? I am pretty confident on the front speakers and the Oppo as being a good versatile player. However, I have never owned McIntosh gear and close to $7k for an amp is not cheap. The Marantz is under $2k so is reasonable. I have a Rel Britannia B1 sub in our stereo system for30hz on down so am pretty happy with Rel tho not so confident on HT use. My main concern is the McIntosh and whether I could get similar or superior performance for fewer dollars.....

Thanks for any thoughts or suggestions.

I'd consider one of the Class-D multi-channel amps from Wyred for sound... they will be significantly lighter, much more energy efficient, and will likely sound as good or better than any of the amps mentioned above.

They have a model that offers 5 channels with 221 Wpc into 8ohms or 368 Wpc into 4 ohms for $1999. Unless the other power-hungry amps or the aesthetic appeal of the McIntosh is worth another $5000, of course...
Planning on a Samsung 75" 8550 4K TV. Price is just under $5k. I thought about the 85", but we will only be about 9' away so not realley "needed" and wife thought 85 too big. I am waiting for a quote on rest of system to see how much room they have in pricing. They won't discount the TV, but should give 10% or more on the rest depending on the piece. I think 12% on speakers, but not sure on the electronics (I hope more). The amp is the hardest decision. Thx for the suggestions. Keep me coming! I was trying to stay to $25k but suspect wight the above equipment, I may be looking closer to 30k. This is at the tail end of a major (for us) home renovation. Been bleeding money for the last six months. At least this money will result in more fun than a new roof.....;)
I think the Marantz is the 7702 but not 100% sure. They were quoting $1699 so it might have been the 7701 and, if so, I know Crutchfield has them for 1199.....

Anyone have any thoughts on SF Olympica 2 versus 3? I am thinking with a sub, the extra 5 hertz may not be worth the extra money $3,500 more).
I like the Butler TDB5150 that my brother is using.

For what its worth, I went from Wilson Duette's to the Sonus Faber Olympia 2's for my fronts and I'm very happy with them. You could save some money on the amp by going with the Theta Intrepid.
