If you really want a terrific bottom end it doesn'y cost anywhere near ten grand but it does involve 4 subs. $3k will get you there easy. And I know, because I have that terrific bottom end- both the speakers and the cart/turntable. Which by the way you left out the other key ingredient, the phono stage.
I just upgraded from Koetsu Black Goldline / Herron VTPH2A to Soundsmith Strain Gauge and it is head and shoulders better in every way except the bottom end. Koetsu/Herron simply was fabulous. Will be upgrading the power supply to hopefully get me there.
This is all by way of explaining everything matters. You could get my Koetsu/Herron, we know it produces absolutely superb bottom end. With just your two speakers however you will hear only a fraction of it. I know. My Moab have superb bass. Probably because the woofers are so far apart. "Distributed" being the key word in Distributed Bass Array. Even so, turn on the subs, it is a whole different experience. Not so much because "more" but mostly because better.
If you go this route do yourself a favor and disregard the "get a sub" people. One sub, or even two, only worth doing if en route to four. Do your research. You will find the only ones arguing with that have no experience on which to argue. While every single one of us who has a DBA knows.
Hopefully you can take all that put it together and figure out what will work for you.
