I have been listening with the Voce and the new to come out, Linear Tube Audio, Z10e (brand new and current model). The Z10e uses EL84 tubes in the power section with 12AU7 and 12AT7 or the excellent 7062.
The sound of the Voce, with well recorded music, for me, get to the heart of what sound can be. I listen to a lot of live music. Hearing timbre that truly represents the sound, making it identifiable as to source, isn't always easy and is often glossed over. Either things are hyper presented, as Dan notes in his HiFi definition, or the individual sounds that make up the whole, are not discernible and grounded in reality. That is one reason, among many others, I enjoy the natural sounds from the sources, as a gauge, rather than listening to a lot of recorded music and making up my mind from that. My wife plays flute, I used to play sax and violin and currently play harmonica so the enjoyment of the "sound', is what I am always after.
The Voce, I am finding, is able to reach this pinnacle. The layering, imaging, when it is there, air that carries the notes, timbre, and breath of life are there. I have to say that the finalized Z10e goes a long ways in giving the Voce what they need and both are world class. One thing that does stick out, as I normally prefer live performances that are well recorded, for their acoustical properties, is the combination here, is able to make studio recording so much more enjoyable. There is a drive and momentum to the beat that gets you there, both on well recorded live and studio recording, rather than "wishing" you were there.
