I don't know about "final", but I am happy with what I have and don't see changing anything in the foreseeable future.
Main equipment:
Classe CP800 preamp
Classe CA2200 amp
Emerald Physics 2.8 OB speakers
Rythmik G22 Dual-opposed 12" sub
Yamaha CD-S2100 CD/SACD
Synergistic Research cables/fuses/etc...
My go-to artists would be Rush/Yes/Pink Floyd/DeBussy/Beethoven/etc....lots of classical, but pretty much anything that's exceptionally recorded, especially on SACD.
