There are many, many better ways to spend $1K especially if MUSIC is your main focus.
First off:
1. Will it be 2-channel music or multi-channel music you'll be doing?
2. Room dimensions? Totally enclosed or open plan?
3. How far from the speakers will you be sitting?
4. Which music genres do you listen to the most?
5. Where did you find the DT fell short with the most?
6. How important is FORM FACTOR and WAF? Do you HAVE TO HAVE something tiny like those SVS sats?
