You would notice the difference between the Yamaha C2 and the C2A preamplifier. The C2A was a major improvement over the C2 and is reflected in used prices. This old stuff sounds great with one caveat: it is approaching 30 years old and you have to assume that service is required on all of this old stuff. I have been there and done that and it is not cheap unless YOU do the work yourself.
There are so many excellent values on the used market made within the past ten years that a piece that is 25 years old has to be rather exceptional to be of interest (think McIntosh MC225, Bedini 25/25).
A new Antique Sound Lab tubed phono section at less than 300 new with some basic mods can sound very good is what people in these forums have reported. Used preamps such as an Audible Illusions Modulus 3 (say 700, 650) or an Audio Note M2 Phono (around 900 used) are good values and very, very good.
