Bro, take it easy, you should better check all the options and mainly enjoy your gear, a couple of weeks ago you got your new set of n3ap, a terrific set tbh, with the Zx300 it’s a bomb, mainly in the balanced setting. As someone who has walked that path, try to check as much info as you can and get familiarized with your gear, believe me, if I could go back, I would save myself a ton of money. How are you liking your current set? Tbh, it’s hard to dislike the wm1a signature, for me it killed all my Other daps, mainly cause of sq and battery life, sound wise, I know there are better things, but they cost around 2,000 usd and upwards, fiio makes really good stuff... but I don’t like the lack of organic feeling in the sound. I had m11
And tested m15, m15 is amazing, but not my cup of tea, even the zx300 has a “lively” vibe rather than some modern daps. Right now I’m using it with my Sony’s xb75, all I can say Is that I could have saved so much money... but there’s people who could argue, i use simple things when at work and at home I pull my high end gear
