Tube pre amp

Most tube pres use tubes like 6SN7 or 12AX7. 

Some more exotic pres use direct-heated triodes like the 300B or 2A3. I’ve heard here and there that these DHTs are the best for their soundstand / imaging capabilities — is this true?

@madavid0 I think those qualities you are describing are typically applied to DHT amps, preamps using those tube types are fairly rare.

Thanks guys trying to get as much information on the tube preamps mated to a solid state power amp!

Rogue Audio RP-1 or you could find a used Rogue Metis both are very good at affordable prices. I have the Metis and have been very happy with it.

How about a used Herron Audio VTSP-1?  VERY GOOD performer.  Doesn't sound tubey, just very clean.
