Combining 2 channel audio and home theatre


Hi, i'm trying to find out ways to maximise audio quality from my system. So basically i'm running a 5.1 system connected to my Denon AVR. Even though i'm pretty satisfied with the overall movie experience, i'm still trying to find out if there's anything i could do to bring out the most out of my system within my budget to improve the quality of 2 channel music experience. All my sources are digital (TV, TIDAL via Nvidia Shield) and i have to do it in the same room.

My setup:
Triangle Borea BRO3 for my front left and right. ( 100W, 90db sensitivity )
Denon X3700
I've set it all up in my bedroom, pretty small space. (Roughly 2.5 m distance from the speakers.)


Alright, so here's a few things i'm considering .

1. Getting a separate Power Amp: Since these AVR's power ratings are not so reliable and i've read from several sources that it's good to separate the amplifying and pre processing to get a clean signal.If i do this i'll still have my Denon as a Preamp and i'm not sure if it'll have any impact for Music. If i do, how much of improvement will i get in terms of audio quality (Not loudness as my listening space is pretty small) and is it worth the extra expense?

2. Getting an Integrated Stereo AMP: Okay so this is a bit tricky for me. Since my music source is only TIDAL via NVidia Shield connected Straight to Denon, is there anyway to practically make both my AVR(For movies) and Stereo AMP(For Music) work together? I understand that i have to connect using the Preout from AVR to Stereo AMP, but it will basically make the Integrated Stereo AMP work like a regular Amplifier right? As in, the audio pre processing will still be done by my AVR since my music source is connected to the AVR. I wanna keep all my sources connected to the AVR and fully make use of the Stereo AMP(both it's preprocessing and amplifier) when listening to music, as well as switch to 5.1 while watching movies. is that possible? Even if it is possible, will it bring a big difference to the audio quality?

Among these 2 options, which is the best way to go? Or is there any other ways to get an even better result? My budget is around 700$ .


I have been trying to find this info everywhere to integrate hifi stereo with a 5.1 setup and all i could get is by connecting the audio source, ex Turn table, directly to the stereo amp and making the connection to AVR via Preout. I wanna keep my AVR as the main hub and listen to music via TIDAL. I'm pretty new to this and It'll be really helpful if you guys could help me out!

FYI, i don't wanna change any of the equipments i'm using as i just got them recently. I'm very satisfied with my Denon for movies and the sound signature i get from my Triangle BRO3's are really good too, it's just i wanna know if i'm missing out on anything to bring out the full potential of these speakers.

Your partially right you should get an integrated with a built in streamer and take the left and right outputs of the receiver into the integrated creating a much purer way to derive the best possible performance outof your main loudspeakers
Thanks for the reply! 
Built in streamer as in like, the ones with spotify streaming from the phone? What are the available options out there? 

But even if i go that way, it'll be a wireless streaming and reduce the audio quality right? Anyway i. could play the master audio's from Tidal? 
@audiotroy Okay i've found a few Integrated Amp's with built in streamer that supports tidal. Thanks for the suggestion! i'll definitely consider this. 

But how about my first step? if i just connect a 2 channel Power Amp to my AVR, will it have a noticeable good difference in the audio quality? Since, through this method, i’ll be giving a good quality dedicated power amp to power my L/R rather than the low grade ones from my AVR. Basically, through this method i’ll be turning my AVR into a pre amp. I'm just confused that if the pre amp function in Denon AVR is good enough and match that of an Integrated stereo amp? 

and one more question, adding an integrated amp or a Power amp brings major difference in the audio quality? that leads to my previous question, is the preamp function in an AVR as good as the ones from an Integrated stereo amp. 

Sorry for asking too much questions, I'm pretty new to this.
