Wow, great to know that your 104.2's are still working. Mine died after 30 years of sweet sounds. I preferred the 104.2's out from the front wall and away from the side walls as much as possible. I prefer this for most speakers but furniture placement and being able to walk in a room can affect the best placement of speakers. I would say as most others, since you have them, place them where they sound best to you in your particular room. All the best with your 104.2's. I loved those speakers.
