I am glad to hear you had that opportunity @charles007100
You described pretty well what I consider the Volti house sound.
Also glad you got to compare them with some Klipsch. They may look similar on the surface, but surely sound different. My pair of Volti Razz replaced a pair of Klipsch Heresy IV's. The difference is stunning. The volti's never shout or hoot at me, they remain sweet and smooth, even at high volumes.
In comparing the Razz to the Lucera or Rival, the bigger brothers carry the house sound, just bigger and wider in my opinion.
I have yet to hear my Razz paired up with anything other than tubes, (a Cary SLI80HS to be exact). I've heard the Razz sound great with First Watt, and PASS amplification as well.
Listened to them once with border patrol SIT amp, maybe 5 WPC.. still amazing.
