Hey Rooze,
Well, I thought I will stick with my Legacy Whispers for life. I have always been curious about the Avantgardes and when a local dealer had a preowed Duos for sale, I rushed to audition it. After the first few notes on Chuck Mangione's Feels So Good cut, I knew right away that I had to sell my Whispers. I sold the pair immediately and then a very nice pair of preowed Trios became available here and, after a prolonged negotiation with my wife (to divert some of the money due for my kid's college funds into these monstrous speakers), I was able to pick the pair up in New York and I know I am set for life with these fantastic loudspeakers. The Duos will make you feel a sense of connection with the music. Forget being over analytical and just really enjoy the music being played. You will be immersed with sheer musical pleasure with the performers having the "Breath of Life" right there in your presence!
Also, I just marvel at the fact that a mere 1 watt can power the Duos to room-filling levels. I am used to owning monstrous high-current, high-wattage amps and it took a while for me to accept that a few miniscule watts can produce such a magical experience that envelopes your whole body and caresses your soul. Again, just a suggestion for your consumption! All the best!
