It is a good idea to purchase a vintage tube pre-amp.

The Harmon Kardon Citation 1 preamp is excellent when properly restored. To find one like that would probably be more expensive than the preamps listed, but it can keep up with them easily. A very competent circuit!

The Dyna PAS-3 is not a particularly great preamp, but it lends itself very well to update and modification! I've seen them be giant-killers on many occasions. We've done mods on them for decades and our UV-1 is heavily based on those mods. You can find used PAS-3s for $200-$400 depending on condition- and likely they will need refurbishment at that price.

Our own MP-1 has been in production since 1989. So I guess that can qualify as vintage; it features a direct-coupled output that allows it to be quite transparent; the real issue is whether you can find one.

One Classic pre that I don't believe has been mentioned is the
conrad johnson Premier 3. While its some 30 years old, the sound was excellent when paired with solid state amps.

Another happy owner of a Don Sachs Model 1 6SN7 tube pre!

Don will customize his preamp to ensure it integrates well with your amp, and offers a large choice of upgrade options.

Well worth checking out!

I have heard that ARC drove the tubes really hard in the SP-10 but not so hard in the 11, but do not have personal experience.  For the same money if you are patient you might find a CAT SL-1, with which I have had over 25 years experience.  It's a wonderful preamp with a first rate phono section.  All I've had to do to it is replace one capacitor in the power supply and that only about two years ago.  And I bought mine used.
Happy shunting.
