review my list please


Hello everyone. I am new to the high end world of home audio/video and am looking to build a system that i will be satisfied with for a long time and hopefully get it done on the first try. Music and Movies will have equal weight so i'm hoping for the best of both worlds. It will be going in our 2 story family room 23'x18'. The back wall is half open to the kitchen and the left side (facing the tv) is open partially to front rooms and upstairs rooms. I know this isn't a great room but I'm hoping it can sound great with only modest acoustic help. I would welcome any comments and suggestions in regards to the list of components I have so far. Thank you.here is my list.
TV- Samsung 85in. Q90
Mcintosh MX123 Processor
Mcintosh 8207 AMP
Focal Kanta 2 towers
Focal Kanta center channel
Focal 300-ILWCR6 surrounds
2X REL S-510 SUBS
Panasonic DP-UB900 Reference Blue Ray Player
Sonos Port Audio streamer
Audioquest cables

I've tested the 8805 in my system.  It's an excellent processor for the cost.  Large power supply and discrete analog output stages.  Very good bass, punch and midrange body and fullness.  However, it is voiced slightly warm with slightly rolled off high frequencies.  It's a great product.

I haven't heard the MX123, but it's also very well built.  I don't know if it's similar to 8805 or if it has better high frequency response.  Either product will likely,

I wouldn't recommend Audioquest HDMI cables.  They did not perform well for the price you pay.  Audioquest interconnects and speaker cables are good.  So are the power cables.  There will be a million different opinions on the best cables and this is a "can of worms" question, lol.

I would recommend older WireWorld Series HDMI cables that do not have the DNA Helix design.  The older Silver Starlight 5-2 or Starlight 5-2 or 6 are excellent.  If you're on a budget, the Neotech NEHH-4200 HDMI is excellent for under $100 and will perform as good as the much more expensive WireWorld 7 Silver Starlight.

Thanks for the feedback. I’m leaning more and more towards the 8805. The savings would allow me to bump up to the kanta 3. I will definitely research the cables to make the best choice I can. 
I like Samsung but some of the larger tvs have an odd connection setup with all connections into a remote box (power too) and a scary thin umbilical cable to the back of the tv, like pencil thin. Saw one and I found it worrisome.
Hello everyone. I think I’ve finalized my list. I’m going with the 8805 over the Mx 123 and switching to the blue sound node. Also Focal had a flash sale of 20 percent off so I upgraded to the Kanta 3. Thanks for all the great advice. I’m looking forward to seeing how it sounds.
