share 2 CH speakers with HT set up or use separate speakers for front end of a 7.2 HT?


My TV/Listening room currently has 2 separate front ends.
One for music and one for HT/TV.
The 2 channel set up is a Lyngdorf TDAI 2170 into Dali Helicon 800s towers.
The HT set up is Denon X3500 into an AV1213 front end utilizing book shelf speakers for L&R

The room is only 13’ wide and the speakers are kind of close to each other.
I’m wondering if I should ditch the cheaper AV123 book shelf speakers from the HT set up and use some kind of switcher, as long as it doesn’t degrade the signal I get out of my Lyngdorf / Dali 2 CH set up.

I was switching speaker cables for a while (with just one set of speakers for the front end) and I found myself not using my 2 channel set up much because the cable swap was a pain.

I'm sure the Lyngdorf has a HT bypass but my brain is having a hard time figuring out what that actually is, even after reading a few blogs on it,  or if I should be using it. 

What do you folks think?

Thank you so much everyone.  I'm really looking forward to simplifying and bettering my audio chain.
I sort of jumped the gun on the Lyngdorf info. I actually just got it today, about 2 hours ago.
So it’s still not even the chain, but it’s the first pre/amp I’ve had that had HT bypass in it.
@imhififan I really appreciate the breakdown. Do you own the Lyngdorf? You sound like you’re speaking from experience with the unit.

No, I am not a owner, but I had some experience setup a TDAI 2170 when my friend got his unit.
Since your Dali Helicon 800 are full range, so my suggestion is not to connect subwoofer to the Lyngdorf to simplify setup.
Hi,
when in stereo bypass mode, can you still see tv video on tv, absent sound of course, and can you change channels? If yes, is functionality quick and convenient?  Denon has a video select function, does it continue to work?

i like seeing video when listening to stereo and can do this with marantz avr, when I use a streamer.  I press the cd source button to switch to streamer and channel being viewed stays on.
I use my 2 channel set up for TV and theater every day. I only get positive comments on the sound. It is a very big system with 4 subwoofers but I have no rear channels and do not feel the need for them.
