Replacing surround with sound bar

I think I would use surround more if it were provided automatically by the TV.  I haven't used the eARC/HDMI converter enough to know if it transmits surround.  I do use HDMI from the Ayre DX-5 DSD to the Bryston SP3 for Blu-rays.  In my OP I didn't mention that I'd like to end up with the single 4-tier rack of Ayre gear and KEF Reference 1s I have now -- a fine sounding setup, or KEF LS60 with the Ayre DX-5 DSD as the approach to my simplification goal.  In either case, gone are the SP3 and NAD amps.  At 87 I feel the need to downsize and simplify.

I switched to the Sony soundbar added the bigger sub and smaller back channel loudspeakers and have been very happy.  I was using a 2 channel with single subwoofer setup run through a Roksan analog preamp.  I took the analog audio output from the television.  It sounded good.  I then got a bigger, newer TV with very limited analog outputs and thought I should do something.  The sound, particularly dialog, is much better with the Sony soundbar, but the setup and convenience are far, far superior to the previous 2 channel movie playback.  It's all wireless with automatic room optimization and I can use a single remote for all television/streaming viewing.  Unless you're trying for some sort of statement multi-channel viewing experience I would highly recommend the Sony soundbar.

I have not used the Sony for music playback.

The model I got was the HT-A7000.  It's being discounted right now.  Could be a new model coming?

Several years ago I replaced NAD T765 with PSB speakers and Mirage sub for a Bluesound sound bar to down size. 
 

I haven’t regretted it though I use my tv as a monitor for Roon probably more than for tv or movies. 
 

It’s an option and if aligned with your priorities can be worthwhile 

There is a big difference between a real surround system and a soundbar, even a cheap surround system. I would do what you have to do to keep it. I’ll be honest, I’m not sure I understand the eARC issue. The last time I upgraded our TVs… suddenly all the TVs and surround systems and sound bars suddenly started working together under the eARC input. I only had to upgrade my HDMI cable to 2.0 or something like that.

But I understand. My partner is disabled and bedridden, so we have a 65” and a soundbar in the bedroom. I think it is pretty easy to show ~ best is the Sennheiser Ambeo. Add a small sub and you have really good natural sound, but not surround.

@ghdprentic Sadly many early generation HDMI processors have no ability to take sound from the TV.

If you only use external sources like Roku, a BD player or a cable box then it can go through the HDMI processor without a problem. It’s when you use, for instance, the Netflix app on the TV that you are pretty much out of luck.

Of course, one other alternative is to use the digital out from the TV which normally supports at least 5.1.
