Stereo Preamp suggestion


I intend adding a Stereo preamp with HT bypass and subwoofer out to my setup below
KEF R900 mains
KEF R600C Center
KEF T301 surround
Pair of SVS SB3000 Subs
Mains are connected to Parasound A21+ poweramp and the rest is connected to Marantz AVR 7011.
Im looking to get a stereo preamp with HT bypass so as to enhance the music listening experience.
Any thoughts on which brand/model of preamp I could go for considering that I want the subs also to be activated while listening to music. 
I am looking at the following models of Stereo Preamp:
1. Parasound P6
2. Parasound JC2BP
3. Anthem STR 
4. Rotel 1590 MkII

I am using the Marantz AVR for both music and movies. 
Fronts are connected to the Poweramp and yes the subs are connected to the Marantz AVR. Since the AVR is the only source for both music and movies, subs are on when the AVR is on.
I thought by adding a stereo pre, it would sound more musical rather than listening thru an AVR.
@elliottbnewcombjr 
thank you for the elaborate response. I intend going for the second option of adding a preamp in between the AVR and power amp.
as for subs (sealed ones) location they are adjacent to the L and R mains so that is not a concern as such.
From the posts so far I believe only P6 or Anthem STR would fit the requirement. Unable to decide which one to go for since STR has the ARC which is being raved about. 

@tony1954Thank you for the response. Yes I have read this link earlier
My source is predominantly Tidal, Spotify and youtube. Let me know your thoughts around Anthem STR if you have come across since it has the ARC and If i understand it right, it has the flexibility on tuning the subs suitably.
Thanks everyone for the responses. Truly appreciated.
I am now deciding between Parasound P6 and Anthem STR as only these two fit all the requirements. While Im inclined towards Anthem, it costs twice as much as P6. Not sure if its worth the spent on Anthem only for the ARC and the stereo sub option which is not in the P6.
Further, since my source is Tidal and Spotify, Need to go for an audiophile grade streamer to go with my system.
Any thoughts would help. Im thinking of Node and Cambridge CXN V2 as of now.
