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?

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.
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.
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.
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.

Since you already setup and calibrated the Lyngdorf for stereo playback, all you need to do is add HT bypass to it:

1. To setup HT bypass, disconnect front L/R speakers on the Denon and using a pair of interconnect cable connect the Denon front L/R pre-out to the Lyngdorf one of the unused analog RCA input. Enable that input and set it to HT bypass.

2. Power up both Denon and Lyngdorf, on the Lyngdorf select that HT bypass input. Turn on the setup manual on the Denon, use the calibrating mic and do the 'auto setup'.

3. Now your systems are ready for HT and 2 channel stereo playback.

4. For HT playback, power up both Denon and Lyngdorf, on the Lyngdorf select that HT bypass input, at this point the Denon will take over all control functions such as volume control, channel level, surround mode...

Hope it help, and enjoy...

I had the same dilemma sometime back. I was using an AVR to drive Kef LS50s but wanted to get into 2 channel. I was limited to a smallish room. I picked up a used Peachtree Nova 150 which has HT bypass as suggested by the folks above. 

I connected the front out of the AVR to the Aux/HT Bypass input of the Nova 150 and it worked like a charm. As Erik mentioned; when the Nova was in HT bypass mode, the AVR controlled the volume.

My scenario was further complicated by the need to share my subwoofer between the two systems (love the LS50s but not very much bass) . I used a Schiit Sys to share the sub. It worked a treat but required manually flicking the Sys between the AVR and Nova 150.  

Your Lyngdorf has HT bypass and the owners manual walks you through the configuration. Just pick up that interconnect @imhififan mentioned. 
HT bypass means that the Lyngdorf gives up the the volume control.

No matter what level you were listening to music, when you use HT Bypass the volume gets taken over by your HT processor.
My suggestion is go for HT bypass, what you need is a pair of interconnect cable.
