Upgrade to Maggi 3.7i or Tekton Moab?


I’ve got a dilemma. The audiophile bug to continuously tweak and upgrade has got me wanting more and bigger sound out of my system. I’m currently running Maggi 1.7is with a single SVS SB2000pro, driven by Parasound A21+. What I’m finding is in my large room (20x18 with vaulted 18ft ceiling, leading into open kitchen) it just does not deliver the uumph that I am wanting when I want to "feel" the music hit me. I am debating what my next step should be when I am ready to make the jump. Should I go with a bigger Maggi (3.7i) or should I abandon planars and go with the very alive sounding Tekton line. What I have read so far is that the DI and Moab sound very alive. That I think is that sort of thing I feel is a bit thin with my present system. I am expecting to hear (fairly so) that if i want to feel music hit me in that chest, a planar speaker is not for me and I need to go with dynamic driver. That said, I do love the transparency and cohesive sound of the Maggi, so I want it all I guess? =)

Welcoming any advice or food for thought on this.

Like anything where you will spend some coin, it would be worth an audition.  Having said that I love my Magnepan 3.7is.  I have them paired with a couple of subwoofers (L/R channel).  As you probably already know, Magis work best with  a high-current amplifier (I’m driving mine with a Musical Fidelity NuVista 800 integrated amplifier).  Good luck on your purchase!

I have two friends with large listening rooms with high vaulted ceilings. Both with large speakers and subwoofers.  No bass.  Personally I think you run into a problem that it is very difficult to pressurize a big room to get adequate bass and dynamics.

As others have already said, in light of the above the answer to your dilemma is Moab, without a doubt! 
Your Parasound seems more than adequate to drive a pair of Moabs.
