Help! Receiver or preamp? Im overwhelmed...


I need some help. Been gone for years and much has changed and Im just overwhelmed with the years of info on the forums. I dont want to make a foolish decision and would so appreciate the communities gracious knowledge and assistance.

Im 75% music and 25% HT. 

Gear:
Paradigm Studio 100 v4 mains Paradigm CC690 center 
Paradigm V2monitor surrounds
SVS PB13 Ultra Sub
Emotiva XPA 5 amp (200x5)
Keeping all the above

The old 5 channel Rotel HT1055 receiver (no HDMI) needs to upgrade even though I love the sound! Im fine with 5.1 and not interested in Atmos. Im also fine with a used item. What do you reccomend for some killer sound and updated HDMI?

Love my Pioneer SC LX81 but depressed looking at what they're worth now; sounds great with 2 ch and 5.1.

My LG is OLED but pre 4K and still does it for me- still a fantastic easy to watch tellie
The Anthem MX 520 cost me about $1100 when purchased from my dealer.  There may have been a slight price increase in the year since, but it should be close to enough to your budget to justify a little stretch and the advantage of owning a new component.  I greatly prefer Anthem sound without Room Correction to Marantz and Denon.  With ARC, it’s not even close, imo
@mahler123 How would you describe Anthem, vs Marantz and Denon, or Rotel for that matter? 
The Oppo suggestion would be good if they hadn't been out of production for at least two years, with used units going for 2x (or more) of the original purchase price.  The new Anthem multi-channel units look good, although if you're keeping your 5-channel amp not sure why you want a unit with internal amplifiers.
@Fatdaddy I guess because AV processors seem to be over the budget and receivers that have internal amps seem to have a lot going on for a reasonable price. You would think units without amplification would be less than those with...go figure.
