Absolutely the Quicksilver. I have a Sonic Frontiers SFL 1 and it is a great preamp but it was built in 1994. Some have had extensive mods through Parts Connexion and they still repair them so it's not a bad choice. The reason I say Quicksilver is because their stuff is all point to point wired. Plus it's built like a tank.
I have had Quicksilver Mid Monos since '15 and they have been rock-solid reliable. I have their headphone amp, also huge bang for the buck.
#1 Quicksilver
#2 SFL 1 , you could do a lot worse. Also built like a tank
#3 VTL. STAY AWAY !!!!!! HORRIBLE SERVICE, HORRIBLE PEOPLE
