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.

I listen to all kinds of music. Don’t get me wrong the Magnepans are wonderful. The Moabs are way more dynamic. The bass is the best I have had. The high efficiency of the Moabs, affords the use of some very special lower power amplifiers that simply did not work with the Magnepans. Soundstage, imaging and dynamics on the Moabs is first rate
If you want slam-me-in-the-chest bass like you used to hear at hard-rock band concerts, you need two stacks of 24" woofers about 30 feet high.

Other than that, the Maggies are transparent, so garbage in, garbage out. I suppose you can add a few Hartley 24" woofers if you want that old-day BANG you are seeking.

Funny, I wonder where everyone making box speakers today got the idea for "tall" speakers?  It couldn't be from Jim Winey, right?

Of course not.  Before Magnepan, people listened to Klipschorns, I think.

Enjoy!

I have no listening experience with the Tekton Mohabs but I recently auditioned the Maggie 20.7i and 3.7i.  I chose the 20.7i, but the 3.7i were very similar in tonal quality and the holographic soundstage lots of folks equate with Maggies.

I decided on the 20.7i's because of the large mid-bass panels and I thought they may not need a subwoofer.  Well as many Maggie owners do I ended up adding a subwoofer and happy I did so, 

I keep the sub volume very low and a low pass frequency of 50Hz and a slope of 18 dB so as not to interfere with the terrific mid-bass sound the Maggie's produce.  This produces the uumph that you may be seeking.

I mention this as adding a sub to the 3.7i's will likely get very close to the overall sound I get from the 20.7i's as they share the same ribbon tweeter and the mid bass panel size is close.

Hope this helps.
