Combining home theater with two channel


I have a 7 channel home theater system. In my system, I have Marantz 7706pre amp, Emotiva XPA-Differential 3 channel(450 wpc) driving my golden ear R1s and center channel, XPA-4 (275 wpc) driving surround speakers. When I switch to 2 channel to play music, I’m just not impressed with the emotiva.
My dealer suggested that I add an integrated amp to the system to play music.  The krell K-300i. I just have a hard time understanding how can a 150 wpc amp pack more of a punch than a 450watt amp.

Hi Peytoni,

I had the same experience as you while back and went the HT Bypass route.  Here are a couple of my discussion threads for reference:
https://forum.audiogon.com/discussions/optimizing-ht-setup-for-analog-where-to-begin
https://forum.audiogon.com/discussions/best-integrated-for-my-purposes-help-me-choose-1-of-3

I wanted to retain the mostly good HT performance, but didn't want to compromise any 2-channel listening.  I realized early on that my setup just wasn't optimum for the LS50s.  In the end, I went with a Parasound Hint6 - I couldn't be happier.  I was even able to sell my phono pre as the hint6 was better all around.  Just awesome.  There is a bit of inconvenience (for the family... not me :) when having to switch the hint6 into 'bypass' mode, but other than that, just a great setup.  Can also be solved with a smart remote.  

Anyway, no matter which way you go, a fully dedicated analog signal chain is where it's at! 
I prefer two separate systems.  The only commonality between my AV and audio systems are the main speakers,

When I want to switch from one to the other, I just take the speaker wires out of one amp and insert them in the other - I have a tube audio set up and a solid state video set up.

I have played music through the video sources but the sound from a mass market AV preamp, while quite decent (I also use a Marantz) is inferior to the stand alone audio set up.
You can’t get around the two system part. toasted my 25 year old Bose Lifestyle HT system. I’m about to go with a Nad t778 and pass through the additional back surround channels. I don’t really need the video switching though as the TV handles that fine. Started wondering about a tube amp as an old Sansui (smoked it) was so smooth. The money to power dual 15 JBLs with tubes is too much so I’m sticking with a Crown for the stereo. I personally just love the club sound levels and the JBL bass. I’m also getting addicted to the MQA (albeit less pure than analog , but convenient). Any insights into a sound only system that will process MQA and provide for HT pass through without the video? The Nad seems like one of few choices. MQA/ HT pass through and atmos are my hot points.
I also just purchased an NAD T778 and Monolith x5, with the intention of adding a Holo Spring 3 DAC KTE, and switch between them with a Goldpoint SA2 https://www.goldpt.com/sa2.html

The Spring 3 KTE can be ordered with a discreet, hardware Class A preamp module and I think that will be a wonderful setup.

This will allow me to hookup a REL T/7x subwoofer using both the LFE to the NAD, and the high level speakon connector directly to the Monolith.

Just got the nad t778 out if the box. The

JBL SR4732 don't even need the Crown when hooked

up directly to stereo. Normally I'd have configured this six ways to Sunday by now but I'm paralyzed with the excellent sound. When I get better configuration experimentation I'll post back. BUT this Nad has the power solo if I do choose. So HAPPY 😎
