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?

What's your budget?   This will probably dictate what we recommend.  Such as under $1000.  $1000-3000.  $4,000 or more. lol.
