There is a lot of information about things that can impact audio quality if you search online. There is no way this issue can be explained in a few paragraphs here.
The sound levels you obtain when using an analogue or Bluetooth input depend on the source. If the sound from the soundbar is not loud enough, increase the sound level at the source.
Again, audio quality also depends on the source material. If you are listening to old MP3 files, it doesn't matter what type of connection to the soundbar you have, the audio quality will be poor.
Most TVs will pass through audio from one of its inputs to the HDMI-ARC as-is without converting it so while the HDMI-ARC (or eARC) has a much higher bandwidth than other connections and can support higher quality audio, it can't improve or change the audio quality it sees on its other inputs.
If you are listening to audio only from external sources, you are better off connecting those sources directly to your Cinema 600 using the Digital (optical) input if you can. If not, use the analogue or Bluetooth inputs.
You will get the best audio quality from your TV using the HDMI-ARC connection. This will allow you to use your TV's CEC functions to turn the soundbar on/off and control the volume using the TV remote.
The Cinema 600 supports "Dolby Audio" but there are many types and only the most basic one, Dolby Digital, is supported. Dolby Digital can provide 5.1 surround sound via the HDMI-ARC or Digital connection but it cannot be considered high quality audio. Dolby Digital Plus can provide "CD Quality" audio but only via HDMI-ARC or HDMI-eARC. Unfortunately, the Cinema 600 cannot decode Dolby Digital Plus.
If you want higher quality audio and higher sound levels from your Surround 3s, you might want to consider a Cinema 800.
It will work with your existing Surround 3s.
It has two HDMI connections on the soundbar so you will not be restricted by any limitations your TV may have.
It supports Dolby Digital, Dolby Digital Plus, Dolby Atmos, Dolby HD, and more.
It supports HDMI-eARC so if your TV also has HDMI-eARC your soundbar will be able to process higher quality audio from your TV.

The Cinema 800 does not support any up/down positioning and there is no way to connect additional speakers needed for full Atmos positioning but it does support Dolby Atmos, provides better positioning of sound than does Dolby Digital and provides much higher quality audio.
I hope this helps...
My name is zak and I am writing from Italy. I would appreciate it if you could help me locate the original firmware for my Klisch Cinema 600. I purchased it with a firmware version of 65.0.0, but now I have 31.0.0, which I want to return to the original firmware version. Can you help me? I would appreciate any help you can provide.
