Stuck point!

Hi, 
I am returning to the experts to get an opinion. I sold my PS Audio M 700 mono blocks thinking I was ready to pull the trigger on the Wellsenton R800i. I know their are great similarities between some of the Line Magnetic amps. around the same price point of just under $3,000, almost identical except for tubes. So, their are options if I chose to go with another well known brand. Here are the issue/s..  I have a fairly small treated room and I keep hearing it will “heat the room up.” I don’t know if it will be problematic or an overstatement. Plus the issue of bass. It may not produce good base which is a problem since I loved the class D amps bass. Lastly, speaker sensitivity, most of my speakers have 87db and up except for the LS50’s. Thanks, don
