Hi, yes i can suggest an amazing DAC for you in your price range. I have owned it for about a month now and it is the third DAC i have owned and by far the best, read the reviews. OK, it's a Cambridge DacMagic Plus. The price is $350 on Amazon and do get the optional BT100 so you can wireless stream to it, that adds another $75, so $425 total. It's not an extreme "Hi End" component but as a number of reviews state, it should spank anything in the price range you mention,
Happy listening!
