On a whim I scored an amazing deal on the monolith 365C center channel. Now, it appears I am invested in a new setup. I am coming from a klipsch synergy 5.1 set I got in 2011 with an Onkyo NR 515 AVR. Since then, my tastes have changed...\n\nI'm going to start with 5.1 for now. My listening will be 50\/50 movies\/music. Atmos is out of the question because of my vaulted angled ceilings. However, will be moving at some point and a rectangular HT room is a requirement for new house.\n\nI'm going back and forth on getting the monolith 365Ts right now, or waiting for the 460 towers. Don't care about Atmos unless it's discrete speakers (will do in new house). \n\nAlso, I am thinking dual monolith 10" or 12" subs, or SVS 2,000 or 3,000s. I generally prefer sealed, but am open to new things.\n\nFor the AVR, looking at Denon 3600 or Onkyo rz840. Both seem somewhat future proof and allow me to upgrade to atmos when the time comes. The monolith towers\/bookshelves are 4 ohm rated.\n\nDenon is nice because it allows you to separately amp the front three when all other channels in use and has the discrete dual sub outs. However, the Onkyo appears to have more power and some features I like - mainly more power and the ability to go into a "stereo only" mode where it shuts everything off except for what's needed to drive the 2.1 music. This seems really cool to me.\n\nFor surrounds, I am just thinking NHT super zero 2.1s. I might be out to lunch, and please let me know if I should go bigger here... The room is very large and open to the kitchen, etc. but the couch is also close to one wall, so it's not ideal at all for surround speaker placement. I will need to wall mount the left surround. Right surround will be placed on a bookshelf much farther away. This is my life for now... I'm thinking the nhts because they are so cheap and I can upgrade later at little cost when my space is better. They also are on theme with the 5 speakers having good mid-high range and then just doing good bass management with dual subs to round it out. I'm not going in wall speakers.\n\nLet me know your thoughts. First time poster, long time reader. Thanks!
