Sounds like what you are looking for is definitely a tube setup. With those speaker choices you are in good shape. Lots of good info provided already. I will chime in with my two tube experiences. I had a Jolida 502 brc (entry-level for sure) with 6550 tubes pushing about 60 watts. Loved the imaging, soundstage, and midrange texture. But, not enough oomph for my Snell speakers. So, went up to a Rogue Atlas 100 watt amp using KT-120 tubes. Much better dynamics and bass but not as good in the imaging, soundstage, and midrange dept IMO. Still very enjoyable though. I have heard el34 based systems that blew me away with their midrange and palpability so maybe that is where you should look.
