Veloce Audio makes or at least used to make an upscale "Lithio" series rechargeable battery powered amp and preamp. They were fantastic with YG Carmels. Their price has since bombed on the used market. I would love to own them but afraid they would be boat anchors pending battery replacement availability.
Why no high end battery powered wireless speaker systems?
I would love to have a set of wireless battery powered high end speakers and subwoofers. With so many high end powered speakers and subwoofers around these days, it would seem to be the logical next step to make them battery powered and eliminate all the cables. I'm a little surprised that Sonos hasn't created a wireless system yet with their Play 5 speakers -even though I don't think they have any interest in cultivating the audiophile market. What are the hurdles standing in the way of this? Are there any in the works?
