Tbg, Yes, they do those little Zilplex bowls. They are amazing and flexible. You must know what you are doing but there is almost a positive effect. When I got my (All Ceramic) Contrivas, I didnt install them to get used to the Tidals. Later I reported that the results are lesser then with the Avalon Opus. But now with little readjustments of the ceiling Zilpex, I got the disappearing walls again in the same way as with the Opussen (4-way). The setup must be in order, the Zilpexes cant do wonders but then they connect with the music and the musicians are surrounded with air and space. Listen to Eva Cassidys: Autumn Leaves (Live At Blues Alley) and she is there
Not a perfect album in the audiophile sense but very very involving. Like the Tidals slogan We Build Emotions you became emotional connected with the music.
Another hit is Patricia Barbers Yesterday and also her interpretation of Autumn Leaves from Nightclub.
There is something else what I sense with the Contrivas more then with other speakers: There is a specific volume (plus or minus a few dbs) that is perfect for a specific song or title. Sure it has to do with your room and whats in it. But when you reach this level then PLOP, youre transported to the musicians or they are transported to your room, depending on the recording and or mix. All these thing happens also without the Zilpexes, but they make everything much more easy. The do a little bass control, lift the height of the voices, makes your podium wider without loosing dept and many more.. Its Magic and its NOT.
