I happen to like the sound bar a lot. It has more than enough bass for my area that I watch TV and listen to music. Although the Surround 3's are very low volume. I had one fail recently. It started having far lower than usually volume. It was barely audible with a lot of hissing static noise. I've spoken to Klipsch and I'm wait for them to verify my purchase from Amazon. For a replacement. Hopefully the new ones will have louder audio than the ones I had. I could barely notice them until I hit about 50% volume which is much to loud for my living situation. I rent in a smaller house the whole second floor of a nice home. It makes the paintings shake on the walls downstairs at that volume. The people I rent from are elderly and don't really watch TV. It is way to loud for them at that volume. I even used acoustic panels to lessen the volume perceived downstairs. I can't turn up the adjustment any more than 4 dots on the soundbar for the Surround 3's. Is there any way to improve that? I was also curious about improving my input audio to the soundbar. I use a pretty decent HDMI cable that's speed is 48gb per second from my computer. Is there an HDMI DAC with video pass through or am I stuck only using a DAC with the 3.5mm aux input. If using a conventional decent but no where near high quality balanced 3.5mm cable. It made for a much lower volume output from the soundbar compared to the ARC audio connection. I use it from my desktop PC into my TCL QLED TV. Then into the soundbar to take advantage of the TV's remote since I'm limited on desktop space. I have no expansion options on my desk due to the unusual cut out area built into the home I rent from. Is the aux 3.5mm input on the soundbar low quality or is it an inferior cable and DAC? I know the PC integrated DAC sucks but I made a small improvement using Equalizer APO using the Peace GUI and HeSuVi plug in software. It's short for Headphone Surround Virtualizations for Equalizer APO. Works great on headphones but with the quality of the connection to 3.5mm input on soundbar. Be it the cable, integrated DAC, or the aux jack to the soundbar is way to low compared to ARC HDMI. I do have plans to put a high quality sound card into my PC in the near future. Although it doesn't have HDMI and using that companies software will make a ton of improvement. Given no HDMI output. I seriously doubt the software will make much difference on the integrated HDMI output from the PC. What are my options using a DAC? I don't think many. I could only find 2 or 3 HDMI DACs. I'm hoping the low volume through aux was due to Realtek crap DAC from PC & a crap aux cable was the cause. I can use that connection via other devices and it plays loud. Hopefully the 3.5mm aux input on the soundbar isn't low quality as well. If anyone has a better way to improve my audio please let me know other than replacing it with component audio. Which isn't really much of an option in this location. It has all wood paneling along with the roof slope makes for an usual room geometry. Even the ceiling is wood paneling that I really don't want to damage or hang speakers from. I can't use Dolby Atmos speakers that bounce off the ceiling because it will reflect in an off sort of way. Ceiling speakers aren't an option either because of the depth between ceiling to roof area is only 6 to 8 inches at best. I am hoping others have gone down this road so that I may benefit from their experience. Regarding audio quality improvement for the Cinema 600 in the 5.1 configuration. Thank you for your help in advance, Larry D
