With regards to the original topic, I've owned Merlin VSM-MXe (bought used) and currently own Gallo 3.1 (bought new).
Which do I prefer? It's hard to say, they have different strengths and weaknesses, but in my experience they are both truly excellent speakers.
Merlins
Strengths:
* Most coherent and "clear" sounding speakers I've ever heard probably
* Incredibly transparent
* Reference quality tonality for music with mid to smaller ensembles
* Great imaging and staging
Weaknesses:
* With the disclaimer that in my personal system, my room, my preferences, IMHO ,etc. and everything, they were ultimately a bit on the lean side for me, in the lower mids and upper bass. I used a Cary Sixpac EL34 amp.
* Macrodynamically challenged with bigger music, ie. orchestral and big rock compared to speakers with more and bigger drivers
Gallo 3.1
Strengths:
* Excellent Macro and micro dynamics (beats Merlin in Scale)
* Staging and imaging at least as good as the Merlins (for me)
* Very holographic and airy presentation
Weaknesses:
* Not quite as clear and crisp as the Merlins in the mids and highs.
Ultimately these are two speakers in similar camps - they are both ultra high resolution speakers capable of sounding very very good. Both are created by very talented designers. If you want a bit more meat in the lower midrange and the bass, go for the Gallo. If you want more clarity and open-ness in the mids, go for the Merlin. No losers here IMHO
