LOOKING TO UPGRADE FROM BW 805 NAUTILUS TO COMPACT FLOOR STANDERS


I have a pair of BW 805 Nautilus speakers and was looking for a change which would give me a bit more bass than the stand mounts I currently have in a compact floor standing set.  

My current set up is a McIntosh D100 preamp with a McIntosh MC 2105 power amp.  I've been considering ProAC and Spendor.  Any other suggestions would be greatly appreciated.

I'd be willing spend up to $4000 but am unsure whether there's anything out there that would make a significant improvement in a compact floor standing set vs the 805's.

My room dimensions are 15' wide x 20' long.

The proac D20r are excellent speakers but I'm not sure how they would pair with your McIntosh solid-state amplifier. They are a easy load to drive with a amplifier problem is they do like tubes. They have plenty of bass if their positions correctly. Happy Hunting
I went from a pair of B&W Signature 805’s to the Proac D-30R’s. As nice as the B&W’s were the Proac’s were a huge step up. I find the D-30R to be a much more engaging and musical speaker. Also they are easier to drive and a bit more room friendly than the B&W’s.

Good luck
How about a pair of Dynaudio Confidence C1s? They are no longer made, but they can be had used for less than your price. I've never owned them, but heard them once in a store demo and was astonished by how much bass they delivered. (I used to own B&W Signature 805s.)
Just a thought.
