1961 bookshelf vs 1723 Bookshelf S Thx?

The LS3/5a has been in production over 40 years.   There are still about five companies making them.   But they don’t play loud.  And they don’t have any bass.

But people like the big image.

The 1961 bookshelf has the big image and people do like that about it.

When you bump up to the 1723 S bookshelf you get a little move bass.  And a little more volume.

My question for those of you who have heard both:

When you go to the 1723 do you lose more of that ‘huge image’ than you gain in bass and volume?   Do you lose something in the ‘big image’ department when you go to the 1723 from the 1961?

Are the gains in bass and volume with the 1723 meaningful?

I sure wish I could hear both.

Any comments welcome.
