Tinnitus worries...

Racer, if your willing to pay the price and explore diet, I have evolved over the last 30 years into a now gluten-free, flour free vegan. Research suggested to me that any flour restricts arteries for about 8 hours after ingesting. I forget the %, but it's over 25 for sure. Could it influence hearing? I'm not sure because I do not have this issue. Simply put, stick to veggies, fruits, nuts, seeds, beans and gluten-free whole grains for a week and see where you are at. It clearly helps my air flow among other things.
Apologizes to all who might feel this is off topic.

As far as diet and tinnitus, its not fat, its salt/sodium, alcohol and of course caffeine. And maybe what lpretiring mentioned but I have not gone down that route yet...
Sodium was the big one for me. You would be surprised. Cut it out as much has possible for a few days or more, then eat a pizza or big meal out or something high in sodium (most american or asian food) and then see what you hear... I now keep all meals down to 500mg or below...but thats just me. It helps.

As far as your system and room affecting it...YES, this can indeed be the case. I went through this very thing. My system sounded great but there was this almost 'unheard' high freq resonance that would set my ears off within moments. Ridding my system of glare and harshness on the power side helped but it wasn't until I properly treated the room --especially the back wall in my case-- then it was gone! I of course still have tinnitus BUT sitting in my listening chair with music no longer exacerbates it. 

I would bet your tinnitus is not actually worse in the last month, you are just concentrating on it more. Although, I have gone though three 'upticks' of it over the years and then there is a new learning curve to get to the point of not noticing it again... But do not dismiss the system and the room. Glare from your systems power and the room acoustics have a huge affect on what yo are hearing. It worked for me. And my systems sounds even better, too. 

Great, caffeine and alcohol, the only things I drink.

when your young, you can get away with just about anything.

Unfortunately lpretiring, I'm at the other end.
