Rogue Dragon VS PS Audio BHK VS Carver 350

I have a rotation of speakers.  Some more efficient than others.  Most of them are 4ohm nominal.  Adding Magnepan to the mix.  So I can expect 1-4 ohm.  My Arcam is good.  But,  If I bridge for power it it may not survive. 

The LSA looks very interesting!

Would be useful if you post photos of your system / space under your ID. Helpful in understanding your needs.

I saw a Voyager yesterday for $1700! Hurry before he wakes up and increases the price

If you want flabby/uncontrolled bass but nice midrange, go tubes. I have the BHK signature because it sounds great and it has input tubes with solid state output.
I will always use a higher powered amp in my dedicated room no matter if the speakers require it or not. I have always found that providing a powerful amp (250 watts or more with good reserve, not class d) will get the best out of the speaker.
