However, the Bluetooth sound quality left much to be desired. Compared to pairing the Golden Ages to my iPhone 14, the ECHO MINI over Bluetooth had a noticeably lower resolution and a sibilant, less refined presentation.

The dynamics felt flat, the bass lost texture, and the highs sounded grainy and metallic. Vocals and mids also lacked depth, making them sound one-dimensional.

Presence with the music is an element I cherish, along with resolution and transparency. Presence is the end product of a lot of variables — probably most of them. Think dynamics, inner detail, timbre, shading, and proximity to the soundstage. The result is that the musical image reaches out from behind the plane of the speakers all the way to my ears with a continuous sense of reality. The Synergistic Vibratron goes a long way toward bringing that image forward, but the sound from the speakers has to be excellent to begin with. In lesser systems, the music is confined behind the plane of the speakers and the reality of the recording venue fails to break through that plane to reach the listener. The music is ‘back there’ behind the speakers and not in the room in front of the speakers. The PowerCell 14 brought most of my music right into the room with me. I could play it softer than normal because of the greater resolution and transparency, and I could rock the joint because it was so clean and dynamic. With some listening sessions lasting several hours, I never tired or became irritated unless the recording was really bad — and there is an easy cure for that.
