If you have the room, I would consider a small amp and DAC (perhaps even an integrated one), and some quality bookshelf speaks. You'll have far more choices and improved SQ with that type of config, than limiting yourself to powered speakers.

Really don't want disturb your topic, but please guys, anyone can tell me how i contact the Forum's Admin? can't find the option... i created a topic on "Amplification? and really don't know why it was simply erased... there was. nothing irregular with the topic... what's happening? i'm a new user...
Thanks, sorry for disturb you guys...

In passive speakers, you could pick up a pair of Klipsch bookshelfs well within your budget, such as the RP-150M's - https://www.amazon.com/Klipsch-RP-150M-Bookshelf-Speaker-Ebony/dp/B00RXHEIHE
