Help, which preamp to buy from my shortlist?

Looking to buy a "near vintage" preamplifier. Between these, which of these do you recommend based on experience (sound quality and build quality)? Or which of these wouldn't you buy based on previous experience? I like all of these based on price, condition and compatibility (input & output impedance, etc.) but can't decide on one (or even two). My source is strictly line level (computer based with DAC).
