Looking at after market audio options and have gone through many posts reading about Reuss, NVX, and BA Design, and and LH. I am looking for pros/cons of each system though and what would be best for my profile. I am not an audiophile, I do not have FLAC files, but feel the standard audio on my 2016 S 85d, CPO (black nose type) is very flat. Its definitely super flat when EQ is 0-0-0-0 and then I changed EQ to 5.5, 3,0,3,6 and it was better, but still doesn't feel like my Cadillac ATS. I used to have Cadillac ATS 2013 with Bose Audio and the Tesla system is just bad compared to that one. I want to at least have Bose Experience. My mornings I listen to slacker, and tune in, and a lot of CNBC (yes talk radio, listen to business and stocks). I am thinking I just need a Sub, and Amp and connect to current speakers and that might be fine. I was looking at the: NVX Powered BOOST Kit for 2012 and Up Tesla Model S (PBK-TSLAS-VCW104) Would this be enough to make the audio experience I am looking for? Reuss at first glance appears to be a lot of money. Ideally I'd like to spend like 1500 to 2k -- maybe Reuss at 3k is okay, but not sure. I am not the audiophile and dont listen to flac USB, I'm more the typical audio person and listen to lots of talk radio like CNBC. I also really wish had XM I had that in my Cadillac and liked it a lot. I also look at LH and BA Design. Nxt vs BA Design ? What would you choose? I was learning towards NXT cause BA design seems to also have mixed reviews. Would you suggest another setup, or car installer? I am in Arizona and do not have the luxury of all the CA shops. If you suggest installer in Arizona I can go see them as well. Or suggest other sub/amp combos. I am thinking I just need the sub / amp and plugin into existing speakers. I can always upgrade other speakers later if needed. Thanks.
