It depends what sound you are looking for. Any Amperex from the Heerlen, Holland factory will have the widest soundstage, nice mids and sound sweet in a Rogue preamp. Cleartops have excellent high-end extension, are detailed and open.
RCA Blackplates are a different direction to go...warmer, yet very open (a classic NOS tube sound).
I've also tried Siemens, but found them too analytical.
NOS Amperex are expensive and in great demand, RCA are affordable and very high quality.
