Amp for JBL 250 Ti

you should use Reyaudio mono amps(top model) never heard thise jbl's better period.

I responded to your post on AK for a Mac amp. For other potential amplifiers you may want to consider an with a higher current high headroom amp like a Mark Levinson 23.5 or a Jeff Rowland model 5. Super high current and I think better bass control. Both can be had at a more manageable price point

I would use McIntosh amps.......
