The Creek is a very good option. The DLC is also quite good. I like the Chase because of all it's capabilities even though it is a passive design. I've actually used it as a line stage while my tube pre was away for mods.
I have used both the Creek OBH-12 and the DLC in the manner you intend to use them, although not with vintage gear. The DLC suited my system better, especially for the used prices.
