I would say it depends on the particulars of the components you would like to
put together; some match well, some don't; and that is true for tube or sand.
System synergy is always important, but I don't think it is correct to
generalize tube vs. solid state.
My Pass First Watt solid-state amp is closer to a Fi X tube amp in sound than
a Linn solid-state amp, for example. The same can be said for tube and sand
preamps and tube vs. sand CDPs. I currently use a tube CDP (AA prima) into a
Fi Y tube preamp and Fi X tube amp, and everything seems to come together
quite well, no exaggerated tube softness.
The only consistent thing, I realize with every additional piece of tube
equipment added to my system, is a certain sense of realism to instruments,
whereas solid state can be slightly flat in that respect. But then
again...excellent ss stuff out there as well.
Just my 2c...
