I learned at some point in my life that I am not responsible enough for nice things. I prefer to have less expensive items, I'm not very careful with them and it doesn't matter so much. I cannot be so careful. I think it's about objects or material goods, that I just cannot treat things so preciously, it's just shoes or a coat, or a car. You might think that would be different with a guitar, that I'd have some custom ax with a name that I baby but no, I actually prefer something a little less needy, something I can kick around a little and something I won't mind if there's a scratch or ding, cause I've known myself for a long time, there will be a scratch or ding.
I say all this to preface that I don't have much experience with very expensive acoustic guitars but from what I've seen and all I know, spending more money will not really help you sound better. High-end guitars are built better, with better materials so they will last longer, and they definitely play better. You can feel it in your hands immediately. The fretboard feels easier, and that may help you play better. I can make a slight exception for soundboard or top of the guitar. There is a difference between a solid top and a laminate - pieces glued together - for sound and projection, though this is not a very expensive level.
Nothing will change the sound of your instrument like new strings, or a different type of strings. It's such a journey to find the right strings for you and for each guitar, the ones you like, the sound you like. First, you need to try 20 different types of strings. Reviews will help narrow down the search, but as usual, you have to put them on your instrument and listen, feel, to know what you like. And you can't just pop them on and off, switch them out quickly and hear the difference. It's a long process. You have to know what sound you're looking for of course, but then you have to see what's available, and hear all of them. All strings sound a little bright at first, then they break in or wear in a little, before eventually going flat. So if you have strings for 2 months, *anything* will sound much much better.
I knew a guy who played electric, like 80's shredder guitar, and he said, "you shouldn't have to fight your instrument", which made sense to me so I started with light strings. But it turns out, I like to fight my instrument. I like to pluck and bang the strings like some think wound bass wires. Eventually I moved to 12s and now to 13s, heavier and a thicker, more projecting sound. It took some time for the strength in my hand to catch up but I love this gauge now. Then everything I had was so bright, my plastic pick probably doesn't help that, but I like the dead sound. Not flat but not super bright and fresh. Finally in some dark corner of the internet I found a recommendation for Royal Bronze strings from SIT. I'd never heard of them but I found them locally, on sale as a bonus, and this is what I've been looking for. Who knows for other guitars or later in life but now, on this instrument, these are the strings I didn't know I was asking for.
After that, playing style, intonation, rhythm, these all influence your sound more than spending 2 g's on a beautiful piece of wood. If I had the extra cash lying around perhaps I'd consider, but I always prefer used stuff, it's already got a few dings and I can put a few of my own scratches in it too.
