Help w/ preamp

Hey guys!

A while back I posted about my search for an amp...I got a ton of great suggestions and had decided on demo'ing Parasound and Anthem. I found a local Parasound dealer here in Pasadena, and I was FLOORED. I have been using a Marantz SR 7011, connected to a full Martin Logan setup: Ethos fronts, motif x center, motion 40 rears. I felt like I had never really heard my speakers once they cranked up the Parasound. I told them my budget and they introduced me to the KRELL CHORUS 5200....man, oh man. They had a floor model for sale, as they were making room for a new 7 channel. The sound was similar, but I felt like the bass had more punch, and they made me an amazing deal - something I have yet to find online (lucky me I suppose).  So, after that long story...here's a few questions:

1. I am currently using RCA instead of XLR, as the Marantz AVR doesn't have both. I am sure I am losing some audio quality here correct?
2. I am thinking about adding the Martin Logan AFX (atmos) speakers soon - but since the Krell is 5 channels, I would have to run them through the Marantz - is that a "bad" idea?
3. The store I bought the Krell from recommended I swap to the Marantz 8802 as a pre, and use a 2 channel amp to power the atmos - something like a Parasound A23, which I see fairly cheap on here. Or, I could just sell my 5200, and buy a 7200 (there's a good one on here).

I guess, my main concerns - will the sound seem "different" or "uneven" getting amplified from different sources? Whether it be Krell + Marantz, or Krell + Parasound. And, would I be losing quality running anything through the AVR (I know they are just atmos speakers, but still) as opposed to using a dedicated power amp?

Any and all advice is appreciated. Thanks@

@auxinput, thanks for the response. The 7011 does HEOS, but I don't use it really, so I'm not too worried about that. Budget wise, after buying the Krell and doing other upgrades, the 7703 is more in my range right now....of course, I could wait. What would be the main difference between the 7703 and 8802? 

And would switching over from the 7011 even make a substantial difference? Or is not even worth the trouble of selling my unit and buying another, installing, etc? Thanks again!

@auxinput, yes, I would consider used. would just need to sell my 7011 as well :) 

@randy-11, i have a very short cable run - the AVR is one shelf above the Krell - so I could be okay w/ RCA?

i am thinking of doing some room treatment - its a living room w/ all wooden floors and several big windows...though, they're typically covered by drapes when watchign movies. i am thinking a good first addition would be a floor rug. think that would help at all?

@auxinput, I've heard that too and have no problem using them. But that will come when/if I swap to a pre instead of AVR. Which is my big dilemma. Maybe a more immediate fix would be cabling and adding a rug? I'm using AQ rocket 44 cabling that I got from Magnolia..

@auxinput, I have also considered switching to the Anthem AVM 60. Do you have thoughts on that pre? I have seen nothing but stellar reviews, but when I demo'd their power amp, I wasn't blown away. Granted, this would not be doing what the amp was supposed to do.

I have honestly had some 4K pass through issues w/ the 7011, which is partially why I also want to upgrade/swap. For some reason, NONE of the rear HDMI inputs will support 4K from my Oppo 203 or PS4 Pro. When I use the front HDMI port, it works. But on the PS4, it only allows one of the 4K resolution types to display...its quite odd. Neither Marantz nor Sony has an answer. I figured upgrading to a pre that solely focuses on video could alleviate the problem. 

Sorry for all the questions - I almost bought an Anthem a while back, but I have no way to demo it....

@auxinput, wow thanks for all the info! You are much more versed than I could ever pretend to be! 

I have axfuallt turned away from the avm60 because it doesn't have the USB or hdmi ports on front - which I actually use quite often. 

In my research, a few people gave mentioned the McIntosh MX-122. Looks amazing, but obviously a much higher price point. That would be something much further down the road, as I have already invested a ton of money in a relatively short time.

 I love the sound from marantz, and I had actually actually swapped to denon a few months because of the previous 4k issue I mentioned. Well, that lasted 2 weeks. Missed the marantz warmth I was used to. So I swapped back and never looked back.

I'm wondering if upgrading to the 8802 from 7011 would provide a noticeable difference in sound? I know it's always a good idea to have better components whenever possible, but I'm curious if I would clearly be able to tell the sound apart? Thanks again!
