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?

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.

I have a Rotel prepro, and if you like the sound you’re getting now I wouldn’t recommend Marantz, which has a very different sound profile with a softer and less detailed treble but a fuller, richer midrange.  If you’d like to keep the basic sonic traits you have but just improve it across the board I’d go with Anthem.  There’s a used MRX720 on US AudioMart for $1600 (I’d offer $1300 as Anthem just introduced their new models) that would provide better 2-channel performance but also much better multichannel processing and room correction.  It’s a bit over your budget but a nice step up if you can swing it, but if not you can probably get a used MRX520 for around $1000 but I think is a step down in their ARC room correction.  Personally, if I’m you I’d buy the MRX720 as it’ll give you great all-around improvements and I think you’ll be thrilled.  Anyway, FWIW and best of luck.

You say that an Oppo 205 would do the trick - but can it control volume with the analogue outputs? I ask this because my top end Panasonic 9000 can't - I needed to get a volume control with a remote - so I just caved and bought the best sounding processor I could find used. That was a Classe 800 - it sounds amazing, but can't do 4K - which is why it didn't cost $15K. Compromises, compromises ...
