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?

I’m thinking pre-amp/processor as well Russ. No worries brother. I’m in desperate need of advice as I’m 200 miles from any pro audio places. Much appreciated!
jsbranham7 - I think you may have mentioned some options that might really work for you.  For starters, that Marantz SR7012 just might do it for you.  We happen to have a den w/ Paradigm Studio 100s up front, Paradigm Studio center & surrounds, and an SVS sub.  We've gone both ways w/ an external amp - B&K or Odyssey.  And right now it's neither of them - we're bi-amp'ing the front channels directly from the 7012.  Got that SR7012 on an absolutely super deal (so that may help a little to make things sound darned decent to one of us).  Anthem is good stuff, too - that's prob. my next choice (but it'll never beat the price for our 7012).  If you can get such a deal or try 'em either could be highly recommended.
With your budget, I would recommend a used Marantz AV processor. I've had one for about 6 years, never had a problem. A used Anthem, a better piece, is over your budget.
I’ve had several Marantz ‘s they held up great I only got rid of them because I decided I want to separates. You can always find a good deal on one used

I noticed you said 75% music 25% HT. I am sort of going through the same thing I have separates Integra 80.3 processor and Sunfire Cinema Grand series II 5 channel amp. Thinking of going back to a new receiver also something in the middle to catch the 25% HT but a looking for a used higher end integrated amp to get the 75% music i am getting more interested in. So some choices.
