Get wireless headphones for gaming and movie's.
Do a TV system with a AV receiver and a studio system for your guitar stuff.
Most of what I do is on the desk, computer, guitar, Genelec monitors, gaming, etc
I watch TV like 10% of the time and that's to watch my favorite shows or older shows I like to rewatch like the X files and I don't feel like sitting. I could watch them on my computer as all these streaming apps can be used on the computer as well, but I watch it on the TV so I can lie down as my TV is on the wall.
I don't even have my cable box connected to it, though is included with my maintenance fee. I literally just use my TV to watch X files and other nostalgic shows, whenever I watch lie down and give my back a rest from sitting.
For guitar, there are 2 paths for a bedroom player
A conventional guitar amp, there are 2 types, solid state, and valves. The valve is what the pros use, more expensive, but extremely loud. You will NOT get good tones at low volumes, they need to be driven hard. Even the solid-state amps are very loud as well. I had a 15w guitar combo amp and that thing was so loud, anything more than volume 2 was loud and crappy tone at that.
You have guitar amp modelers, they model the real amps, is like a simulation, you can get decent tone at low volume, but most of the physical ones, do not come with a speaker cabinet. The ones that do suck.
For a bedroom player, the best option is a studio monitor and either a physical guitar modeler or a software DSP modeler.
Right now, I use something called Neural DSP, is a software amp modeler. It works and has a decent tone, but I'm bound to the computer, the computer always has to be on.
Ideally, and eventually, I will buy a physical amp modeler, such as Axe FX or FM3, and put it on my desk.
I went the studio monitor route because you get good tone at very low volumes, the only downside of it is that it doesn't move air like a guitar cabinet would
I could do both options. Purchase a physical amp modeler and a powered cabinet for it and play guitar that way. Then, use my speakers with an AV receiver for everything else. I wouldn't need an audio interface anymore, but of course, that path is more expensive, I would need good powered cabinet and the good ones cost at least $1000, then I would need to buy an AV receiver, and the money I spent on my audio interface, i wont need it anymore
From a financial perspective, it made more sense to buy quality speakers, so I can use them for everything including guitar thanks to the DSP guitar software
If I had gone the guitar cabinet route, I would've needed a powered guitar cabinet and a physical amp modeler, and I would still have a ****** soundbar for my PC which is I had before the Genelec lol
