Need advice on desktop setup with bookshelf speakers

Looking to upgrade my speakers on my desk looking to spend $500 or less. Not sure what to buy was thinking about getting the klipsch rp150m. Would be nice to have powered speakers but I am willing to purchase an amp/dac. I am unfamiliar with them though and prefer not to spend another 500$ If I can avoid it. New to audiophile setups so any advice is much appreciated.

You could get a Topping E30 and a pair of Adam Audio T5V for about $530 total.
