Tube preamp integration

Stacking sub-woofers
Separating subs can cause cancellation of the bass waves. Stacking the subs works much like the stacked mids in a d' appolito speakers design. Wide dispersion horizontally and narrow dispersion vertically. This is the way the subs are arranged in ... 
Gallo 3.5 vs Merlin VSM-MXe
The gallo tweeters are indeed leean/bright/crisp. Lots of glass in your room is no help either. Placement out in the room will help some. Obviously, window coverings as well. The size of the Strada is not going to give you the musical weight no ma... 
Meridian 596 with msr+
It should work right out of the box. Try turning the power switch off/on on the 596. Contact your dealer or Meridian direct and ask for a tech.

Should I use 2 different Power Conditioners?

Speakers for a large vaulted room?
The PSBs are going to be totally different than the Magnepans. I would say a bigger amp or bigger Maggies. Not sure if the bigger ones are more efficient. Other choices would be Soundlab Dynastat 88db or Emminent Technology LFT8 still 83db though....
