Do your research but don't let it overwhelm you. In the end, find something that makes you happy. There will always be something out there that'll be "better".
With that said, there are two companies I think you should take a look: Emotiva and SVS.

https://www.svsound.com/
Both have a direct to consumer model. Both companies have been around for a long time. With Emotiva, I have personal experience with them from when they first hit the market with their amplifiers. I still run their first gen XPA-2 two channel power amp in my main A/V system. I recently purchased their BASX A2l+ to use with a Carver CT-17 I have laying around. They have great customer service and have branched out into many different products to include speakers, receivers, CD players, and surround processors. You can always get a hold of someone there via phone and they're more than happy to talk things over with you before buying to make sure you're getting what you want.
SVS has also been around for a long time. They built their reputation on the subwoofers but have also branched out. I don't have personal experience with them other than listening to a system that was set up at the owner/president of the company's home. By that time, I had already built out my home systems so didn't need anything they had to offer.
One thing I will say is your room is the most critical part of how your system will ultimately sound. Many people forget this and don't factor it in. It really depends on how picky you want to be. I spent the time, money, and effort in having a room built out for my main A/V system which includes acoustical treatments. You mention bass being a priority. Having a sub(s) will get you there. Positioning of the sub(s) is critical in the bass performance. Moving a sub into a corner of the room will provide the benefit of helping boost bass in certain frequency ranges. Being able to move a sub around the room to get the best performance is one step. With the room correction technologies now present in lots of surround processors/receivers and even the subs themselves, this makes fine tuning the ultimate sound so much easier. And if you want to go another step further, adding acoustical treatments in the form of bass traps will also help get you there.
