I'm open to suggestions. Around this range I also found the xDuoo TA-22. It seems like it's a well regarded hybrid tube amp, that might inject a little 'spice'.I've tried nan7 with L30ii. L30ii certainly can drive nan7 to ear bleeding level, but the sound is very dry and sterile. Maybe try nan7 with something less "clinical".
What did you end up using it with to make it less dry?
EDIT: I'm also seeing an open box EF400 for $300.
