hi,my system is naim uniti ,speakers kef ls 50 with concept 20 stands,and n.a.s Western digital.I m happy of it,but really need more soundstage and dynamics.I added nap 200 and i noticed a small jump,and for me doesnt worth the money extra on the nap 200.My thinking is upgrade the speakers,and on my radar pmc 22 or proac studio 140 or spendor a6r.Please any help or suggestion!
