unclechoppy, a few thoughts based upon some decades of experience.
First, the term "bookshelf speaker" has an unfortunate evolution. It is true it connotes speakers of a size and weight that could fit and be supported by a bookshelf. But very few of them sounded as good there as compared to placement on stands and out away from the walls. Your 4th point includes imaging and only a few speakers have been designed to image well close to a wall and surrounded by other objects on bookshelves.
Second, with your appreciation of "vintage audio", understand that some repair/updating will be likely. Many woofers and some mid-range drivers were built with foam surrounds which may not survive even 20 years. Fortunately surrounds can be replaced. Crossovers will likely include parts which benefit from upgrading, particularly capacitors. A number of "vintage" speakers included tone switches with two to five positions. Those too may require replacement. Cosmetics are a personal choice but finding 30 year old speakers with good finish on the cabinets and speaker cloth which is not soiled or ripped may not be easy. Of course they can be restored too.
Third, I've never owned any of the speakers you listed, though I have heard some specifically and others in similar models. From my experiences I can recommend two choices if you want to pursue this. The Dynaco A-25 (or rare A-25XL) if deep bass is not too important, and the Large Advent if bass is important. The A-25 can be driven by smaller amps (20 - 60 wpc) and sound good with either tube or SS of reasonable quality. The Advent will need more power (50 - 200 wpc). I've never heard those driven by tubes but something with KT-88, 6550, or the new KT-150 may be fine. Also, both are 2-way systems, thus easier to restore.
Lastly, the danger in recommending any old/used component is it will depend on what you can find in your price range. I could suggest you get the Blast-off X 1000 but while looking for that you might miss the QRD which would be just as good or better. Therefore, having a list of candidates rather than one specific model will be best. And allow some $ out of your budget for restorations mentioned above, just like that vintage auto.
Good luck, and let us know what you find.
