The auratones are a piece of crap. You could build a better speaker with a cheap driver and a plywood box.

The NS10s are a pretty good near field studio monitor sealed speaker but a little too bright and the mid range is pronounced. I don't like many Japanese made speakers of that era but NS10s are good.

Having said that, for the NS10s, you will need a quality amp(high wattage), because they just don't sound that good with crap components(IMHO). I suggest you find a used/new stereo store and audition a number of amps.

Personally, I like my vintage JBL 4311s and 4312s much better but I use them for home stereo, movies and PC sound.

Happy Listening, the Prisoner.
