i have spoken with Dan Way back when 1988 we hit it off hung out a few times got together at the Listing Room Scarsdale NY & at his Factory in Orange CT Solid State is what he is very good at & had no interest in tubes even its its just output stage I too have tried to Mix & match my Krell Amps With AR tube preamp and a few other big name tube preamps as far as i am concerned it just does not match up i will keep my KRELL Amp & pre amp anytime over tube I do love VAC tube Equipment but then comes the tube insanity of rolling tubes & it just never stops it s one or the other i am all in Solid state M L , J R , Krell will do just fine good night
