Paradigm Reference Studio 100v2. anybody listening?


Looking for advice. Not getting the low end that I feel the 100v2 are capable of. Where am I going wrong? Syztem has tons of clean volume, soundstage. Here is what Im working with: 
Sudiotech stand, shelves are spiked, CD player is on Nordost Pulsar Points, and a Gutwire Note Pad rests on the transport. 
Nordost Shiva power core cor CD player
CD player - Rotel RDC991AE BALANCED 
Straigtwire Crescendo balanced 
PREAMP - CLASSE CP35 balanced 
Audioquest Cheetah balanced 
AMPLIFIER - Mark Levinson no 334 balanced 
Audioquest Gibralter  single biwire 8'

The system sounds lean. Anyone have an ideas?

Yes, I also question the room. Have you had other speakers in this room and or with this equipment that performed well?
Thanks for the replies. It's been bookshelf speakers and receivers up until now. It has to be the room. Going to move some furniture and reposition the speakers. I used the Stereophile test cd and I have a lot of work to do. I repeated the bass warble and while moving around the house to various areas, the bass response was better than in the room? Any ideas?

keep working that Stereophile test CD for best results.
Keep me posted & Happy Listening!
I think I have found the solution. Read the Cardas website for room setup. Moved some furniture. I have the speakers on a different wall and new and improved spacing. Low end is much better. 

I'm thinking of making a change in 
Thanks for the guidance!
