I love that I do the same thing I'll just lay their and let the music take me with it until I start nodding off.
Like you that can take a couple hours for me as well
Last time I had looked at my phone it was 8:30 am and thought I had plenty of time to just lay there. .. next time I looked it was pushing 11! This happens a lot. If the system in my bedroom was as good as my main system, I'd probably have bed sores by now.
The last couple months I have taken to falling asleep listening to smooth jazz but very quietly. When I wake up it's still on but then something good comes on and I'm turning it up little by little until it's pretty loud, and this with just a pair of 6.5" two way full range bookshelf type with an F3 into the mid 30s. The tweeter ( Vifa BC25TG15 ) is no slouch either and it's ability to pleasantly expose all the little details is half of what lures me into these now frequent, horizontal listening sessions.
Only difference is, I have mine on the end my head is on playing at me like headphones (bedphones?) with my head centered between them and they are 7.5 ft apart. When I put them on the opposite end, it created a rather unpleasant bass mode right at my headboard, unless I turned the bass almost all the way down. This way here I get that great phantom center and the bass is somehow just right.
I am sure you will have a lot of fun with the new system and congrats on the good score.
