I'm not familiar with your speakers. Amps and speakers require more attention when being matched than most other combinations. I mention this because my experience with B@K components lead me believe that while the ST-140 has some nice qualities the larger ones with more current out put are amongst the best deals in audio. The M200's offer tremendous value. No, they are not as good as the very best but they come fairly close and at a steep discount. They do sound different than the ST140 in that they are not as warm (in fact perhaps a bit cool) but are so much better balanced as a whole, without the sloppy bass that plagues the St-140. I can't help but think that improving your amp rather than your pre-amp would give you more satisfaction. By the way I like Sonic Frontiers pre-amps with the B&K amps.
B&K vs. Aragon
I presently have a B&K Pro10MC Sonata preamp and ST140 amp combo. I like the warm sound with a Rega P32000 and Dynavector cartridge, Paradigm Sudio 60v2s. What would an equivalent Aragon system sound like (18K or 24K) preamp with
4002 or 2004 amp sound like in comparison? I do not have the luxury of auditioning. I listen to mostly jazz, rock and folk.
