I personally don’t think you’ll find MUCH better at 1k.
You could get slight improvement in aesthetics, tonality, and naming.
SQ? Hard to find a more linear speaker.
Lovinthehd brings up a good point too. There’s a reason Ascend sells the Sierra 1 and NRT for a higher cost. Whether it’s worth the extra money to you is completely up to you.
Edit: Do you have the 170SE or the 170?
