Need suggestions on bookshelf speaker upgrades

Google search turns up nothing on a "Delco 65 recv" (receiver, I assume)?

Hard to say anything meaningful without knowing what will be driving things.

I'm assuming this is not the old GM DElco car audio stuff, right?

Upgrade to floor standing!! HELLO!!

I'm assuming Peachtree decco 65?

Floor standing aren't aways better. It completely depends on the speaker. I have heard tons of monitors sound better than their floorstanding brethren. I'm sure I'm not the only one who will say that. I do like full range better, but floorstanding doesn't mean full range either. There can be many trade offs by adding the much more baffle. Just ask any speaker designer. There is a designer in this thread who has only monitors (I think he only has stand mounted). I'd honestly would love to hear his take on this as there must be a reason he went that route.

Get yourself a pair of Harbeth P3ESR'S and it will be the last stand mount you will ever buy!
