My Soundtouch 300 sounds better in the shop than in my home
I have a ST300 sound bar and Acoustimass 300 that I have purchased last 21st October 2017.
I just realized yesterday when I went to a Best Buy shop and tried their demo, that the sound quality coming from their demo setup (same system ST300 plus Acoustimass300 - no VI300s) was sounding better than my system. The sounds were very much brighter and crispier. Difference can obviously be felt. I also tried playing the shop's system without the Acoustimass 300 - same audio quality difference.... Initially, I was playing their default demo music and movies, so to have the same reference point, I played music and videos via youtube using my phone and connecting via bluetooth.
Also note that I have calibrated my system a number of times and played around with the Bass settings and Center level settings of the sound touch app, but I couldn't get the same quality coming from the shop.
Can you please advise? I recon there is something wrong with my system or maybe there is something else I do not know regarding the settings. By the way, I can still replace my system right? My 90 day purchase does not expire until tomorrow, 18th January 2018.
