Wilson Audio WATT/PUPPY or Gershman Grand Avant Garde?

Great.

Both Gershman AG and Wilson Watt/Puppy became available within driving range from where I live. I'll make a decision by the end of the week.
Again, thanks for all input.

I bought Gershman Grande Avant Grade.
I appears to be power hungry.
To crank up, I need to turn the volume to over 12 o'clock on my 100w, 125w, and 150w amps.
I don't have such wow feeling that I had with Wilson Watt/Puppy a long time ago at audio show. Also, its sound stage and image is not as good as Diva. It lacks liveliness too. 
However, it still sounds better than my Harbeth 7ES-3 and Tyler Linbrook signature. Anyway, it has to be since it costs 2~3 times retail.
I could have gone for Wilson Watt/Puppy 5 used for less price, but due to its size and the need for professional setup, I chose Gershman. It is quite light and I have no problem of carrying it by myself.
Even though I cannot say that I am 100% satisfied, I will stick to Gershman at least for a while (a couple of years) and enjoy the music.
Again, thanks for all your input.

Hi. My room in feet 8.5W/15L/9H, the Grand Avant Garde could play nicely in my room? Thanks for advice. 

I think 8.5W is a bit too narrow. Mine is close to 15W. This speaker may easily overwhelm the room. 

@ihcho are your Amos stereo Amps? I just pulled the trigger on a pair of girshmans. I have tube monoblocks , KT120 tubes and each tube puts out 150 watts per channel. Hope that’s okay and enough power
