Speaker Placement Nirvana

My Spendor S8e speakers are on the short wall of a 15.5 x 18 room. The faces were about 4’ from the back wall, and about 5’ from the sides. I changed amps from a NuVista M3 to a Cary v12, and at 50W the Cary seemed like it was having trouble controlling the bass. It was a little boomy on some albums. After moving them around laterally, I decided to pull them further out from the back wall so the face is now about 5’ out. Wow. What difference that made. The boom is completely gone and everything sounds terrific. The change was NOT subtle. So my question is, what happened and why did the bass respond that way? I could see it if I’d had the speakers placed very close to the wall, but they were pretty far out to begin with. Any thoughts?

Mustang is Ford Mustang, a muscle car.
Schwinn is famous bicycle manufacturer.
I don't think that Grimace solved his problem since he does need current. Changing speaker position is only tweek(valuable I admit).

I'm not sure I'd equate the Cary to a Schwinn...

don't worry what he says
the Cary has low feedback which allows spendors to
project Strings voices and acoustic instruments in a very natural way.
Many a 1200 dollar amps may beat it in the bass but
grain out with the above by comparison playing a violin.
Try marking the top center of your speaker and taking it out from the wall in odd increments 1/3 1/5 1/7 1/9 into the room.
Measure the front wall of the room to the back wall in inches. then divide by 3 5 7 or 9 Place the speakers center mark on these grids with your preference on toe in.
Most odd increments should not disturb room nodes
Enjoy Cheers Johnnyr

Oh! Now I get it!

Of Course, that was the part I got, but since I didn't grasp the analogy to audio, thanks for the clarification.
