Know before you buy
Yes. With four gain levels and a maximum output of 15Vrms in balanced mode, the CA1000 is designed to power even the most demanding audiophile headphones and IEMs with ease.
The CA1000 is a hybrid device that functions as both a high-performance headphone amplifier and a standalone Digital Audio Player. You can store and play music directly from the device or use it as a DAC/amp connected to your computer or smartphone.
It offers excellent versatility with four output ports: 3.5mm and 6.35mm unbalanced jacks, as well as 2.5mm and 4.4mm balanced connections to accommodate almost any headphone cable.
While it features a built-in battery for portable use, it weighs approximately 919g and is quite substantial. It is best described as 'carryable'—ideal for moving between rooms or taking on trips, rather than for use while walking or commuting.
The Crossfeed function mixes a portion of the signal from one channel into the other, simulating the natural soundstage of speakers. This helps reduce listening fatigue during long sessions by making the audio feel less 'in your head'.
Yes, the device supports Wi-Fi connectivity, allowing you to access high-resolution streaming services directly through the interface.
