I have an Ayon Eris. It is a preamp. No complaints. It is not as silent as two other Preamps I own - a Daniel Hertz M6 and an Emm Labs Pre2. This is minor and the 'noise' when one puts one ear to the tweeter is vastly less than surface noise from even a finely fettled vinyl rig. It has 6H30 tubes and they are liquid gold. Reliability: 100% after over two years. It was a store demo so it has been operational in excess of three years.
