Spacial Audio Lab X3 and Pure Audio Project Quintet 15

The Quintets fill a huge room, mine is 16x 27 and vaulted.  Using the Vox 1.6 widebander recommended to me by Ze’ev, and can’t pull myself away. Amp is the LTA Ultra Linear. As DS above, next is the active XO. I’ve also heard the Spatial at the LTA factory, in maybe less than ideal conditions and could happily live with them but they didn’t lure me in like the PAPs. The OB’s appear to take some of the room out of the equation, especially the bass. I have less need to manage the low end energy. FWIW, I also believe that the transformerless amp doesn’t induce vibration into the chassis so vibration management is also less of an issue. If the Covid thing diminishes enough, maybe you’ll have the opportunity at a show to listen in the near future. Best of luck and you are on the right path.  

I think there’s a return policy on the Spatials. I was interested too but have never liked built in subs for whatever reason, so I hope one day to try the M3.

I have a pair of X5’s in a rather large room, 25 x 25 x 8, and they are wonderful. My Rowland mono blocks have way more power than they will ever need, but the image is large, immersive, and refined.
