The Reference Series, was the first series ever introduced by Vitus Audio, back in 2003. The initial two products were the very well reviewed and awarded battery power supplied:
RP-100 Phonostage & RL-100 Linestage
Even though the Reference Series represent the entry level products, they incorporate many specialist/custom parts. This has proven an expensive but necessary must in order to keep their highly regarded musical performance - an area in which they refuse to compromise. While the battery power supply is history, the overall goal of the Reference Series remains unchanged - setting a new standard for sound quality at the price point. A bold, but for us - a true statement.
Once you have heard the performance of this amplifier, they are convinced you will agree. The RI-100 is the first new product in the Reference Series. It is a fully integrated amplifier, which includes an optional phonostage and dac. In it's full configuration, the RI-100 will act as a standalone control center, which takes both analog and digital sources of any kind. It also incorporates a full bypass function for use with external surround processors.
Although the RI-100 does not have the Vitus usual class A mode, it's class AB setting is adjusted for maintaining the same musical performance as our class A amplifiers.
