These are Eversolo's top-of-the-line power and digital preamp, DAC, streamer and DSP components. They are designed to work together and to keep all electronic noise to an absolute minimum. The A10 uses dual power supplies - one for analog and one for digital. Its volume control is a stepped-ladder R2R. And, has a built-in proprietary clocking system. The signal-to-noise ratio is over 130Db!
The F10 power amplifier uses dual differential power modules, dual power supplies and a proprietary DC filtering system. I run two of them as monoblocks for an incredible 950 w/ch and 70dB of current
With the Aerial 20T V2 speakers these components present a huge soundstage that is silky smooth and powerful.
