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.

I just purchased the parasound JC 5 stereo amplifier and the JC 2Bp pre amp to add to my HT. I hope it’s worth the money I spent . In the beginning, one can waste a lot of money on this hobby because of plain old ignorance ,but im learning. thanks to site like this one im getting a better understanding. Thank you all for your help.
Always keep it separate...two different animals. You are compromising two channel by combining out of convenience. Great sound is not always convenient or easy, but worth the effort. Don’t ask what I think about adding a sub to a two channel set up....🙄 it’s "2" channel, not "2.1"...buy speakers that do bass...you do not need to get all the way down to 20 hz to be satisfied..at minimum 35 to 40 hz will be fine. 
Hello,
I have been where you are. I dont mind your purchase. But I feel like you wasted money that you did not have to. Your not buying more speakers so you are combining HT and 2ch together. Emotiva makes a fully differential linear balanced 2 channel preamp. XSP-1. It has HT pass through, subwoofer management, and even matches your amps. It sells for $800 used. It does not have a DAC. I bought a used XDS-2 DAC to go with it for $300 used.  I own this and is very good for the money. But. As long as the Parasound has HT bypass, which I believe they do you did solve your problem very well. HT processors have so much DSP sound manipulation you won’t even notice the front two amps are different. Now that you have two extra amps I think you should add some height speakers. In fact you might get two more of the model you have and do a 5.4.1 system. Or keep the original 7.1 layabout and go 7.2.1. If you don’t have two rows of seating I would go 5.4.2. Yes, get another sub if you don’t have two. I am doing the same you are doing but with the 7704 model. I hope this helped.

A good start in separating the two. The JC2 has bypass. Also, I think the Parasound equipment is pretty neutral, very good quality, and in general, pretty good ‘bang for the buck’. When I was going through this, (after getting more and more into vinyl), I purchased a very inexpensive Parasound ZPre3, with bypass, and am pretty amazed by that little pre. Transformed my system in getting the HT ring out of my 2 channel listening. I would imagine the JC2 will be a big step up. I’m actually awaiting a new Belles Aria Signature preamp to replace my ZPre3 right now.

I really do think you may consider condensing your current HT pre and amp at some point, as your JC 5 will be driving your GoldenEar even in HT mode.
