There is such thing as too much. I once made the mistake of recording a singer with too much tube gear and it was a massive headache trying to mix the tracks. The chain was a Cathedral Pipes Regensburg Dom > Manley Force pre > Tube Tech PE 1C EQ > Urei 1176F > LA2A > Cranesong HEDD192. I basically got a lot of unwieldy 2nd harmonic buildup. Some tube mics pair up well with tube pres, like the Neumann M149 or the Brauner VM1, but I'd rather run a U47 style mic into a solid-state preamp, especially if I'm going to go through the old LA2A.
